Need a way to mount your water/meth nozzle into a silicone rubber coupler or plastic intake tube? The original spec Snow bung gets the job done. Made from Delrin material, you can't apply huge torque, but you don't need to. Simply drill a 3/4" hole using a spade bit, insert the inner adapter piece from the inside, and crank the the nut down from the top. Metal tube applications can use our weld-on bung available in steel or aluminum. Threads are standard 1/8" NPT.
