Overview
PRL Motorsports 4 - Ply Silicone Couplers are top - notch. They feature a 4 - ply silicone construction with polyester reinforcement and a 70 durometer rating. The nominal wall thickness is 0.200” (ranging from.170” to.220”).
- They can handle working temperatures from - 65°F to 350°F (- 53.9°C to + 176.6°C).
- These couplers resist electrochemical degradation, ensuring long - lasting performance.
- While standard silicone hoses aren't for pressurized oil or fuel, we offer special Fluorocarbon and Fluorosilicone liners for better chemical resistance. Contact our engineering team for details.
- They meet or exceed SAE J20 R1, SAE J20 R1 H.T. Class A, TMC RP303B Grade I and Grade II, Mil Spec A - A - 52426, and other heavy - duty OEM specs.
- They have excellent ozone and UV resistance, making them durable outdoors.
- For high - temperature applications up to 500°F, aramid reinforcement is available. Check our website's “4 Ply Woven Aramid Reinforced” section or contact engineering.
- Commonly used in air intake, supercharger, cold - side turbo, intercooler, radiator, and heater core connections, especially in high - temperature or extreme conditions.
- Widely used in aerospace, performance motors, vehicles, marine wet - exhaust, commercial trucks, buses, agricultural and off - highway vehicles, turbo diesel engines, food and beverage connections, and general manufacturing globally.
Using the 4 - Ply Silicone Reducer Coupler is easy. First, make sure the surfaces where you'll attach the coupler are clean and free of debris. Then, simply slide the coupler onto the appropriate pipes or connections. Remember, this coupler can handle a wide range of temperatures, but it's important to note that the standard version isn't suitable for pressurized oil or fuel. If you need chemical resistance, reach out to our engineering department. To maintain the coupler, regularly check for signs of wear, like cracks or tears. Clean it with a mild soap and water solution. If you're using it in high - temperature applications, keep an eye on its performance and consider the aramid - reinforced option if needed. This coupler is versatile and can be used in many different industries, so use it according to your specific application's requirements.
