    Alrighty, cant find it locally, or in any of the normal places, hoping someone on here knows where I can get a brass reducer, from 1/2"x20 to 1/8" NPT.

    Extremely oddball I know, just wondering if its out there. Heck, doesnt even have to be brass, could be any metal, just not plastic.

    so you're talking a 1/2" UNF hole to a 1/8" NPT female? A bushing then? I'll be the first to say I'll bet you it doesn't exist.

    Now a few questions. What is the application this is in. What kind of circuit? Air water fuel oil hydraulic?

    Next, how are you planning to get the 1/2 straight fine thread to seal?

    Next, Are you certain that its 1/2" fine? Could it be British straight pipe, or metric?

    naw, its a friend of mine wanting to put a temp sensor in place of his tranny drain plug. Drain plug threads are 1/2"x20 (bolt threads, I dont know what all the little 3 letter prefixes besides NPT mean), and the sensors threads are 1/8" NPT. So it needs to be threaded 1/2"x20 on the outside, and 1/8"NPT on the inside.


    Just to be clear, something that looks like

    Drill and tap the plug to 1/8" pipe, don't tap it too deep, reuse the original copper washer. easy fix man. I drill and tap 1"-2" 90* fittings regularly for 1/4" guage lines. or other applications.

    A -5 ORB fitting has 1/2-20 threads. You could buy a -6 JIC to -5 ORB adapter fitting and then drill & tap an -6 JIC cap with the 1/8NPT threads. Screw the -5 x -6 adapter in with a crush washer instead of the o-ring. Use the JIC cap for draining the pan.

    You could use AN fittings in place of the JIC (they are identical except for material), but for that location I'd highly recommend sticking with steel fittings.

    Sure, but for all that he could drill and tap the plug hes got.

    other ways..

    I've seen oil drain plugs with a "piggyback" plug in the center you remove to drain the oil--they are 1/2"X20 thread(possibly oversized to make up for stripped threads though)--the center plug is a 1/8" pipe thread...thats one way to get what you want..:laugh:

    But for all the hunting you'll do to find one,I think brazing a 1/2" fine thread nut into the pan would be easier and faster..probably cheeper too!..:crazy:

    Yeah, I've actually bought these before for marine water pump applications:

    part #32-5-2. These are steel, not brass though.
