Reckon this would fit right on my older equipment? I'm using a 1/4-18 female NPSM right now.
Answer by: Customer Support on Jan 13, 2026, 6:50 AM
This adapter is compatible with equipment using a 1/4-18 female NPSM thread, as it features a corresponding male connection adhering to SAE J476 standards. Just make sure the other end, the 1-1/16-12 male SAE O-ring boss, fits your other connection.
Question by: Terry H on Dec 30, 2025, 9:07 PM
thread on the female end is NPSM 1/4-18 -- does that mean it'll hook up to standard 1/4 inch pipe fittings or is NPSM something different I gotta watch out for?
Answer by: Customer Support on Jan 1, 2026, 6:38 AM
NPSM runs on the same 1/4-18 thread pitch as standard NPT pipe fittings, but there's a real difference worth knowing. NPSM is a straight mechanical thread, not a tapered one like NPT. That means it won't seal the same way a tapered pipe thread does. The connection on this adapter relies on the thread engagement per SAE J476, so you'll want to make sure whatever you're mating it to is also NPSM spec and not a tapered NPT port, otherwise you're going to get a poor fit and likely a leak.

trying to swap out an adapter on a machine, is this one male ORB to female NPSM and what thread sizes are we talkin?
Answer by: Customer Support on Feb 1, 2026, 8:49 AM
You are looking at a straight adapter with a male SAE O-ring boss on one end and a female NPSM on the other. The male ORB side is 1-1/16-12 per SAE J514, and the female NPSM side is 1/4-18 per SAE J476.
