Filler Caps and Weld in Bungs

We have been selling weld in filler caps and bungs from the beginning, we have been adding new variations over the years to help fit the ever changing needs of our customers. We have weld in filler neck bungs for most any type of fluid container whether you are making it from mild steel, aluminum or stainless steel.

We have filler caps that are made from aluminum or brass and both are available in either vented or non vented versions. All of the caps and bungs carry the same thread pitch, this makes all of them interchangeable with each other. These weld in filler necks have been used most commonly for gas tanks, oil tanks, and overflow tanks, but can be used for just about any other fluid container. All of these can be found at:

Our new addition to the lineup is our tall style filler neck bung. It has the same 1 1/4″ x 12 thread pitch as all of our other filler caps and weld in bungs so it can be used with any of our previously purchased products. The tall filler bung came about for those of you who wanted to stand the filler neck higher out of your tank with out welding a seperate piece of tubing to the original bungs we already carried. The taller bung can be used just for looks or for proper filling for your application.

These new tall weld in filler bungs also have a small counterbore section for the o ring to seat into. This makes this filler neck better suited for those who need to use the caps in a pressurized system. The counterbore helps retain the o ring from being forced outward from pressure and thus creates a more leak tight seal. The counterbore also shrinks the gap between the cap and weld in bung for better looks. A small gap is still created to keep the cap and bung from making contact apart from the o-ring surface. This will keep the painted surface on your tank from being harmed each tme the cap is tightened down and keep you looking good for years to come.
