Hi all.
Looking for male quick disconnect fittings. Looks like your average fitting that you can get anywhere,such as from PPE, part # pn-352,but can"t seem to locate the correct thread. The od is 12.5 and has a coarse thread. only 3 threads per.337.Any ideas for a supplier?
Sounds like 3/8"G or gas thread. That's same as British straight pipe parallel. Does the fitting have a sealing ring that looks like a washer under it or o ring? If you measure the end of the thread and the top they should be same size. The thread pitch is one thread less than NPT.

no sealing ring,thread same,top to bottom. this mold came from either japan or china. trying to find fittings in case one breaks
Get a thread pitch gauge so you can determine pitch then measure the OD with calipers to figure out what thread they are. Some G threads have an aluminum, plastic or copper seal ring that looks like a washer under them. Others have an O ring molded onto the bottom of the fitting. The area under the fitting will have a flat machines area for the seal. I've never seen a metric fitting from Asia so now I'm curious.

PPE (Plastic Process Equipment should have them, as Rick says, get a thread gauge.
