Hard to find fittings

Used several of these when I set up my shop with air line hookups. Used these to go from 1/2 copper to standard 1/4npt coupling.

1/8 Copper fitting adapter delivery

I ordered (2) 1/8 Copper fitting of an induction coil. I received one 1/8 fitting and one 1/4 fitting. My order was useless and had to use compression fittings which I had in hand but preferred sweat connections. Very disappointing. I also had to pay for shipping for an Item I did not order to return.

I buy a lot of copper fittings and yours are always quality

The product was what I needed, but the descriptions and photos on the web site leave a lot to be desired. Pictures and descriptions on mixed sizes are confusing. Perhaps a link to a 2d cad drawing (ala McMaster Carr) could help.

excellent quality

EPC has always made the best copper fittings imo. Heavily built and with nice large flats to put a wrench on, this copper sweat female adapter is made better than Mueller and some other brands. It even has slightly more threaded area than Nibco. EPC is just better overall.

This fitting (part WP3-08) has 1/2" female thread and is designed to fit over 1/2" copper pipe on the sweat side.

Neither! The female threaded end is 1/2" pipe thread. The 1/2" is a nominal size, you'll find it measures a little larger than 0.5", and it's tapered so it tightens up as it's threaded onto a matching male pipe threaded fitting. With pipe thread joint compound (pipe dope) and proper tightening, it'll hold high pressure. There's lots more detailed info available, search for "pipe threads" on the internet. BTW, the other end of that fitting is designed to be soldered onto a matching male 1/2" solder fitting, and its size is also a "nominal" 1/2", not 0.5". Sent from my Verizon Wireless 4G LTE DROID

Typically when a fitting is listed with only one measurement, the threaded portion is the same diameter as the listed diameter, so in this case, it would be a 1/2" female National Pipe Thread (NPT).

1/2" ct to 1/2" iron pipe. The treads are 1/2" pipe.

Hi, Rossco, the one I got was a 1/2" sweat to a female 1/2" npt. Robert.

It is neither, the female thread is ½” NPT. It is intended to interface between ½” copper and ½” threaded pipe (steel, brass, PVC)

There is no single fitting that can accomplish this, but you could use part WP3-16-08 along with TB12-08-04.

Q: With these copper x female adapters, is the listed size (1/2", 3/8", etc) the ID or the OD?

Asked by 15 years ago

Add your answer

* Required Field
Verified Author and ReplyVerified Reply- PexSupply Staff

The listed size is the nominal size. It is neither the ID nor the OD. The nominal size is the size of the copper pipe that will fit inside the adapter. A 1/2" copper pipe will fit inside a 1/2" C x F adapter, for example.
