Tired of blowing intercooler pipe connections off? So were we! Our Serrated Hose Ends are designed to be welded onto each end of an intercooler pipe connection where your silicone coupler will connect. The serrated end will bite into the coupler just enough not to damage it but make it impossible for the connection to blow off. You can use regular worm gear clamps with them but T-Bolt style clamps will work best.
