These WIX 24003 / NAPA 4003 filter caps allow you to attach a WIX / NAPA filter assembly directly to your muzzle thread without the use of an adapter. They are made form 416 Stainless Steel, use the same o-rings and are much more corrosion resistant and durable than the original aluminum caps. Weight 6.8oz. (193grams)
The center hole of the 1/4-NPT cap is drilled thru to .453" diameter and threaded with female 1/4" National pipe threads so you can attach a 1/4" pipe plug or valve with 1/4" NPT thread.
You can also purchase a solid cap with no hole in the center if you don’t need a drain.
These caps are for Wix 24003 / Napa 4003 filter tubes only and may not fit metric Chinese after market filter tubes.

I am a machinist by trade, and the workmanship and the precision machining that went into these products is outstanding.

Top quality and craftsmanship. Just as I expected. These are very high quality . Highly recommended.

Emphasis on the heavy. The machining is nice and it fits perfectly but it is way wayway heavier than will be useful for any Form 1 builds .
A substantial amount of material needs to be removed from the underside to make it a viable non solvent trap part. Otherwise it is a really nice piece!

I've worked in a Tool & Die shop 2 different times and I know quality work. This is not an easy piece to manufacture, requiring several processes.
A beautiful piece
