Need a way to mount your injector nozzle into your aluminum or steel intake tube? Use our methanol-resistant weld-on adapter! Simply drill a 1/4" hole, place the bung, and weld it into permanent position. As always, these bungs feature 1/8" NPT threads. Alternately, if you prefer to mount in a silicone rubber hose, coupler, or OEM plastic intake pipe, choose our Sandwich Nozzle Bung
Newsflash: Our top-selling aluminum bungs have been improved. They now feature a raised ring in the center to better locate the part during welding. -a little touch to make fabrication that much easier.
