The Mittler Bros. 2-1/2″ Steel Weld Bung is the weld-on bung from the 2-1/2″ fill cap assembly (SKU 1000-302), sold here separately. MIG weld it into your rear-end housing, weight bar tube, or other fabricated component to create a threaded fill point for the aluminum cap (SKU 1000-302A) to thread into.
Ideal when you need to add a new fill point to a custom build, or replace a damaged bung without buying the full assembly. Sold individually. Made in the USA.
