Need a way to mount your water/meth nozzle into a silicone rubber coupler or plastic intake tube? Go with our new CNC-machined bungs. They're made from sturdy aluminum and then anodized for methanol resistance. Far more durable than the oldschool plastic parts they replace, these do not require a gentle touch during installation. 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.
