Boost Products USA silicone couplers are reinforced with textile layers to be extreme pressure resistant, and also to vacuum in your Air Charge System. The hose tubing couplers are suitable for your intercooler system, intake system, water lines or similar, as they can withstand up to 5 Bar and temperatures up to 220 degrees C (not to be used as fuel or oil line). Boost Products silicone hoses have achieved, and many times even exceeded the quality of silicone hoses, compared to ones made by other well-known manufacturers in quality tests. The silicone is durable and flexible, stable, and color-proof for many years.
