Overview
PRL Motorsports 4 - Ply Silicone Couplers are top - notch products. These couplers feature 4 - ply silicone with polyester reinforcement and a 70 durometer. They have a nominal 0.200” wall thickness (ranging from.170” to.220”).
- They can work in temperatures from - 65°F (- 53.9°C) to 350°F (+176.6°C), and are resistant to electrochemical degradation.
- Our standard silicone hoses aren't for pressurized oil or fuel, but we offer special Fluorocarbon and Fluorosilicone liners for better chemical resistance. Contact our engineering department for details.
- They meet or exceed various industry standards like SAE J20 R1, SAE J20 R1 H.T. Class A, TMC RP303B Grade I and Grade II, Mil Spec A - A - 52426, and many heavy - duty OEM specs.
- These couplers have excellent ozone and UV resistance. For high - temperature applications up to 500°F, aramid reinforcement is available. Check our website's “4 Ply Woven Aramid Reinforced” section or contact our engineering department.
- They're commonly used in air intake, supercharger, cold - side turbo and intercooler, radiator or heater core connections, and any high - temperature or extreme - condition applications.
- They're also used in aerospace, performance motors and vehicles, marine wet - exhaust, commercial truck and bus induction and cooling systems, agricultural and off - highway vehicles, all turbo diesel applications, food and beverage connections, and general manufacturing industries worldwide.
Using these 4 - Ply Silicone Elbow Couplers is straightforward. First, make sure the connection areas are clean and free of debris. Then, simply fit the coupler onto the appropriate parts. When it comes to temperature, remember these couplers work best between - 65°F and 350°F. If you need to use them with pressurized oil or fuel, contact our engineering department for special liners. For high - temperature applications above 350°F up to 500°F, consider the aramid - reinforced option. To maintain these couplers, regularly check for signs of wear and tear, especially in extreme conditions. Keep them away from sharp objects to prevent damage. If you notice any degradation, it might be time to replace the coupler. And always refer to our website or engineering department for any specific product - related questions.
