All mechanics should have a dozen of these in their toolboxes for when they need to break into a system and dont want it leaking all over or getting contaminated. Dont forget the mating AN806-4D plugs!

Capped fittings to test fuel tank. Good fittings, good service.

good product.

good price

Works as advertised .

These caps work great to keep critical plumbing and hardware clean and FOD free during service and storage.

These caps (inside plug) are deformed from manufacturing process and DO NOT SEAL! Too much trouble to send back for refund. Exchange would have same problem.
