Tall Weld-In Filler Neck with Aluminum Cap – Vented or Non-Vented

This tall weld-in filler neck and aluminum cap kit offers added height and versatility over our standard filler bung setup. Designed for custom applications like oil tanks, gas tanks, or other steel fluid reservoirs, this taller neck provides extra clearance and can be trimmed down to fit your specific build style.

The kit includes a 1.25" x 12 threaded weld-in bung made from 1-5/8" diameter mild steel and a matching aluminum filler cap—available in your choice of vented or non-vented versions. The cap seals tightly with a replaceable O-ring for a leak-free, hassle-free installation.

This setup is perfect for fabricators looking to blend form, function, and customization into one easy-to-install package.
