BTF Diff Cover Fill Plug & Bung BTF11042
The "BTF Diff Cover Fill Plug and Bung" was designed for use in our line of "Kryptonite" diff covers. The Bung installs and welds in from the inside of the cover so no weld is visible from the exterior of the cover. The Bung is machined on a lathe from cold-rolled bar stock. It fits into a 1 1/2" hole. The Plug is machined to a pipe thread for a positive seal. The opening is approximately 1" in diameter.
