Universal Silicone Couplers
HPSI manufactures a complete line of silicone couplers. These are ideal for turbocharged or supercharged vehicles requiring couplers that can handle high boost and high temperatures. Our reinforced couplers, elbows, and large diameter straight pieces are the highest quality silicone products available. Our silicone is 100% silicone with dense fiberglass matting reinforcement, which provides high tensile strength and temperature limits (-65F-600F).
