The Aeroflow Performance line of premium quality weld-in bungs are CNC machined from solid aluminium billet (6061), CS1030 steel or 316 Stainless Steel. These female NPT weld on fittings have a precision-machined taper to exact tolerances for trouble-free installation of NPT fittings. Applications include, but are not limited to: oil or fuel tanks, radiators, valve covers, manifolds and rear axle housings. Note: NPT threaded fittings should always be sealed with Aeroseal Thread Sealant (AF98-2023) or similar PTFE thread sealant.
