Overview
PRL Motorsports' 4 - Ply Silicone Couplers offer top - notch performance!
- 4 - Ply Silicone with Polyester Reinforcement and 70 Durometer for great strength.
- Wall thickness is nominally 0.200” (ranging from.170” to.220”).
- Works well in temperatures from - 65°F (- 53.9°C) to 350°F (+ 176.6°C).
- Resistant to electrochemical degradation, ensuring long - term durability.
- Standard silicone hoses aren't for pressurized oil or fuel, but we have special liners for chemical resistance. Contact our engineering team for details.
- Meets and surpasses SAE J20 R1, SAE J20 R1 H.T. Class A, TMC RP303B Grade I and Grade II, Mil Spec A - A - 52426, and other OEM specs.
- Outstanding ozone and UV resistance for outdoor use.
- Aramid reinforcement available for up to 500°F high - temperature needs. Check our website or contact engineering.
- Commonly used in air intake, supercharger, turbo, intercooler, radiator, and heater core connections in high - stress conditions.
- Used globally in aerospace, performance vehicles, marine, commercial trucks, agriculture, and more.
Using the 4 - Ply Silicone Straight Coupler is straightforward. Just connect it to the appropriate parts in your system, like air intake or radiator connections. Make sure to check the temperature range of your application to ensure it's within the - 65°F to 350°F limit. If you're dealing with pressurized oil or fuel, don't use the standard hose; contact our engineering department for a suitable alternative. For maintenance, regularly inspect the coupler for signs of wear, such as cracking or degradation. Clean it gently with a mild soap and water solution. If you need to use it in high - temperature environments above 350°F, consider the aramid - reinforced option. Keep an eye on the wall thickness, which should stay within the.170” - 220” range for optimal performance.
