What is silicone coupling?
Silicone couplers (heavy duty pressure connections) prevent liquids and gases from bursting at the connection site, and they can facilitate the flow of chemicals, oil, and water–even when dealing with extreme temperatures. They can be used on intercoolers, superchargers, cold air intakes, and radiators.
