AN5 / JIC-5 weld bung — a less common but important size for specific OEM and hydraulic applications. The WB37-AN05 delivers a permanent 1/2"-20 AN flare port for fuel systems, hydraulic circuits, and custom fabrications requiring AN5 fittings. SS304 construction provides corrosion resistance in fuel, oil, and chemical environments. Ideal for builders who need a precise, weld-in AN fitting port.
Stainless steel 304 weld-on bung for installations in corrosive environments. Threaded for standard AN (JIC) male threads with 37 degree flare.
Need to cap an unused AN port? Pair this bung with one of our stainless steel Allen Key Slotted Plugs (PLG series) using an AN-to-metric adapter, or browse our full fitting lineup to find the right cap for your build.
