They are made to be strong and durable, with five plies of polyester reinforced fibers. A chemical, oil, fuel, UV, and ozone-resistant fluorocarbon lining gives PPE silicone couplers the strength to withstand the exposure to heavy usage and bring reliable, long-lasting performance. Their silicone rubber construction ensures constant boost pressures from -76 degrees F to 437 deg
