If you own a Humvee or HMMWV, you know keeping that beast running right means paying attention to the little things.

This oil filter adapter seal kit is one of those little things that makes a big difference.
It's a brand new, direct replacement kit that includes all the seals and gaskets you need to stop those annoying oil leaks around the filter adapter.
The part number is PB-HEOFAS01, and it crosses over to OEM numbers like MS28775-236, MS28775-20, and 12339409.

Made in the USA, so you know it's quality.

Installation is straightforward—just remove the old seals, clean the surface, and pop these in.

Comes with a 30-day warranty from the manufacturer, so you're covered.
Oh, and quick heads-up: California residents should check out the Prop 65 warning link in the listing.
But if you're anywhere else, just enjoy a leak-free engine and get back to doing Humvee things.
