Pacific Performance Engineering knows the huge stresses that drag racing and sled pulling put on your diesel's parts. Their silicone tubing couplers were designed to handle the rigors of long-distance towing, racing, and pulling competitions! 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 degrees F. They won't blow out like stock hoses will! In short, Pacific Performance Engineering silicone tubing couplers are a smart choice for your high performance diesel!
