Turbo Hoses, Vacuum Lines & Clamps

High Performance Silicone for High Performance Street and Off Road Vehicles

The silicone hose preferred by those who know the difference!

High Performance 4 Ply Aramid Silicone Hose

“High Performance Series, High Temperature hose”

When the heat is turned up, the last thing you want to be thinking about weather or not your connections are going to hold. The limiting factor in a high temperature, high pressure, silicone hose application is the reinforcing fabric layer. Polyester typically starts to melt around 375ºF. This limiting factor restricts the use of polyester reinforced silicone hose to intercoolers and intakes. The inherent high temperatures of today’s high performance turbo and superchargers require a hose that can stand up to the job.  This is why we have reinforced our high performance line of silicone hoses with 4 plies of Aramid fabric.

Aramid is a very unique fabric that has an incredible resistance to temperature. Aramid has been used in extreme applications such as firefighter turn out gear and fire proof racing suits. We chose to reinforce our high performance line of silicone hose with this fire resistant fabric due to its amazing high temp resistance of 500ºF. You may be thinking why not use fiberglass in lieu of Aramid for the temperature resistance? Well we have found that when exposed to colder climates, fiberglass becomes brittle and stiff. Any excessive vibration or movement in low temperatures may become a problem for fiberglass-reinforced silicone hose. When we compared these two fabrics side by side, we found that the extra 50º we could achieve with the fiberglass did not out weigh the pitfalls of a cold weather malfunction

Production starts off with 100% U.S. manufactured silicone bases that are formulated to resist chemicals, ozone, cracking, peeling and extreme temperatures. Our hose is manufactured to meet SAE J20 R1 Class A. Each production lot has been burst tested per the spec and has been inspected for visual defects prior to being released from production.

Applications:

Primarily used on turbochargers, this hose can also be put to work on Intercoolers and intakes, where the extreme temperature range of –65ºF to 500ºF can be utilized.

Recommended clamp/s: Stainless Steel T-bolt clamps, Constant Torque clamps

3 Ply Polyester Silicone Hose

“High quality, affordable intercooler and intake hose”

The majority of all intercooler and intake systems are manufactured using mandrel bent pipe. Weather your pipes are made from steel, aluminum, stainless steel or titanium you will need to join these sections with a semi-flexible connection. High Temp Silicone’s 3 ply polyester hose and couplers fill that gap by providing a high quality affordable bridge between your connections.

Our intercooler hose is reinforced with 3-plies of woven polyester fabric and is manufactured with a standard wall thickness of .195”. This heavy wall construction is more than adequate for most of the intercoolers and intake applications. The limiting factor with this hose is the temperature range of –65º to 350ºF. Although our silicone intercooler hose is quite an improvement over the OEM rubber connections, the temperature range will max out around 350ºF. This limiting factor prohibits the use of this hose directly connected to your turbo, or in very close proximity to exhaust components.

As with our High Performance series silicone hose, manufacturing of the polyester reinforced intercooler hose starts off with 100% U.S. manufactured silicone bases that are specifically formulated to resist chemicals, ozone, cracking, peeling and elevated temperatures. Our hose is manufactured to meet SAE J20 R1 Class A. Each production lot has been burst tested per the spec and has been inspected for visual defects prior to being released from production.

Applications:

Primarily used on Intercoolers, intakes and cooling systems. Temp range –65ºF to 350ºF. Turbo applications should use our high performance series hose.

High Performance 4 Ply Aramid/Silicone Transitions

“High Temperature Silicone/Aramid Transitions”

High Temp Silicone transitions are made to stand up to sever punishment. Unlike non-reinforced silicone transitions, you can mount these directly up to the hot side of a turbocharger. Reinforced with 4 plies of Aramid fabric, our transitions have a temperature range up to 500º Fand are included in our

High Performance Series of silicone products.

Our High Performance Transitions are sold in several different configurations listed below.

Applications: Primarily used on turbochargers, this hose can also be put to work on Intercoolers and intakes, where the extreme temperature range of –65ºF to 500ºF can be utilized.

Recommended clamp/s: Stainless Steel liner clamps, Stainless Steel T-bolt clamps

High Performance 4 Ply Aramid/Silicone Hump Hose

“High temperature vibration solutions”

cHigh vibrations or any movement between your connections could mean you are constantly checking and re-checking your silicone couplers to make sure they are still in place. Misaligned pipe connections could spell an installation disaster. Instead of tearing your pipes out and starting over, we have an alternate solution for you.

High Temp Silicone hump hoses can be installed with a slight misalignment and compensate for a wide range of motion and/or mechanical vibration. Reinforced with 4 plies of Aramid fabric, our hump hoses have a temp range up to 500ºF and are included in our High Performance Series of silicone products.

Our High Performance Silicone Hump Hoses are sold in several different configurations listed below.

Applications: Primarily used on turbochargers, this hose can also be put to work on Intercoolers and intakes, where the extreme temperature range of –65ºF to 500ºF can be utilized.

High Performance 4 Ply Polyester  Silicone Elbows

“High Performance engineered elbows”

During the design of your intercooler, intake, turbo, or supercharger pipe layout, you can rely on our 45º and 90º elbows to help make the turn. We chose to use a 4 ply polyester construction in lieu of an Aramid reinforced construction for these items because they are primarily used on intercooler pipes. The use of polyester still allows for substantial improvement over the OEM rubber elbows with maximum temperature resistance of 350ºF.

Our intercooler elbows are manufactured with a heavy wall thickness of .220”. This heavy wall construction is made to stand up to extreme internal pressures associated with high performance intercoolers and intake applications.

As with all of our silicone hose, manufacturing of the polyester reinforced elbows start off with 100% U.S. manufactured silicone bases that are specifically formulated to resist chemicals, ozone, cracking, peeling and elevated temperatures. Our hose is manufactured to meet SAE J20 R1 Class A. Each production lot has been burst tested per the spec and has been inspected for visual defects prior to being released from production.

Applications:

Primarily used on Intercoolers, intakes and cooling systems where the temperature range –65ºF to 350ºF can be utilized.

Recommended clamp/s: Depending on application Stainless Steel liner clamps and/or Stainless Steel T-bolt clamps should be used.

Platinum Catalyzed Silicone Vacuum Hose

“Outstanding physical properties in a brilliantly colored silicone vacuum hose”

You may be thinking to yourself, what is platinum catalyzed silicone? Why do I need platinum catalyzed silicone? I thought silicone was just silicone? Are there more types of silicone? The short answer is that platinum cured silicone is “the best silicone money can buy”. However instead of just using that old cliché, let us go a little deeper into what it is.

When silicone is in its raw state it is known to be “uncured”. At this stage it is pretty much the consistency of Jell-O. In order for the silicone to take a shape it must be cured with a catalyst. The catalyst can be one of several different chemicals, but the two most commonly used are dichlorobenzoyl peroxide and platinum. The majority of the silicone hose you have seen for sale at the corner auto parts store is made with a peroxide curing system. Most manufactures use this system for a couple of different reasons. The first of which is that it is much cheaper to produce. On average a peroxide system will cost about 40-50% less per pound than platinum. The second reason has to do with the manufacturing aspect of the silicone itself. Peroxide silicone has a mixed shelf life of about 6 months, whereas a platinum silicone must be put into production within hours of mixing.

This very short shelf life, accompanied with the higher cost of the silicone, can create a large amount of scrapped raw materials. Therefore it is much easier for manufactures to make peroxide silicones.

Now here is where it is a benefit to you. Platinum silicones are far superior in physical properties over a peroxide system. In some cases you may see increases of up to 60% in tensile, elongation, and tear strength.  Platinum silicones are less prone to kink or collapse. Because of the tighter cure, they always want to return to the original shape it was cured in (straight). That means when you want to run a vacuum line with a tight bend or corner to turn, you wont have to worry about HTS Silicone Vacuum Hose collapsing on you. They are brilliantly colored, remain shiny and are easy to clean with alcohol. When you add up all of the benefits of using platinum silicone, you can see it is “The best silicone money can buy”!

“Reliable and proven design for heavy duty, high pressure applications”

100% Viton Vacuum Hose

“Amazing fuel and oil resistance accompanied with high temperature resistance”

When it comes to the resistance of fuels, greases, and oils, nothing even comes close to Viton Fluroelastomers. Viton has the capability to withstand the torturous environments associated with the fluids in todays high performance vehicles. Fuels and oils degrade other organic materials at expedient rates. EPDM, Neoprene, and silicone offer little resistance to fuels and oils and start to swell or crack in very short periods of time. Viton vacuum hoses provide that extra level of security due to its amazing fluid resistance.

The excellent high temperature resistance also makes this wonder material a good choice when the application will be installed in a location where excessive heat will be seen.  We are so confident in our Viton vacuum hoses, we offer a 3 year replacement, limited warranty agaist swelling and cracking due to fuel or oil contact.  VVH (Viton Vacuum Hose) is available by the foot in several different ID’s, or you can purchase one of our Viton Vacuum Hose kits at increased savings!

Stainless Steel T-Bolt Clamps

Our Stainless Steel T-bolt clamps have been designed for today’s high performance vehicle in mind. T-bolt clamps offer the protection against “blow-off” without damaging the hose. High Temp Silicone T-bolt clamps provide higher tensile strength, durability and corrosion resistance over typical worm gear clamps. When Installed side by side with worm gear clamps, our T-bolt clamps provide twice the band tension with the same amount of installation torque!

HTS Stainless Steel T-bolts have been manufactured out of 300 series stainless steel to provide a worry free installation.

Applications: Medium to Heavy duty, high-pressure turbochargers, intercooler, and cooling systems.

Stainless Steel Silicone Liner Clamps

“Maximum protection to silicone and other soft hoses while providing a true concentric seal.”

Although silicone is the ideal material to use for your intercooler, intake and turbo application, there are four important things you need to remember about silicone hose. It is soft, hard to seal, expensive and durable when combined with the proper clamp. Our silicone liner clamps were developed to offset the first three and to compliment the durability.

To protect silicone hose from extrusion and shear, an inner liner is used to cover the worm-gear slots.  These inner liners are integral extensions of the band, not separate welded or riveted extensions that won’t lie true to the clamping axis.  There are no bumps under the housing to jeopardize the concentricity of the seal, and no laminated coverings to disintegrate under heat, ultraviolet, chemical or corrosive attacks.

Additionally, our liner clamps are available with .500” wide band to spread the sealing pressure over the widest possible area.  They come in 100% stainless steel, which is important because silicone hose has a service life up to 10 years or more.

Applications: Low to Medium duty, medium pressure intakes, intercoolers and radiator hoses.
