Most Liked Positive Review

35 purchased, all looking good.

I used these to make a DHW heat exhanger going into an old propane tank used as hydronic water storage coupled to a froling boiler. I used a 5/8 reamer in a drill press to cut the shoulder out of the fittings to allow 1/2 tube to pass through & be soldered to together, this leaves me with 8" of pipe coming out of the tank to connect to a manifold and the remainder of the tube to go into the tank as a heat exchanger. These fittings are threaded into a blind tank flange & the pipe flange is welded into a hole in the tank.

It's been a challenge but the only part available

I bought these fittings to step down from a 1" brass tank tee assembly to 3/4" copper lines. I had to redo these connections over a dozen time to get them to stop leaking air during my pressure test. I did pipe dope, teflon tape, combinations of teflon tape and dope. I also tried various thicknesses of tape and varied the number of wraps. The only combination that would work was first coating the threads in a light application of dope. I wiped off the excess to ensure dope was only in threads. I did 5 wraps of thick tape with a lot of tension when wrapping. I did a final layer of dope on the tape. Finally, I tightened to moderate pressure. I don't know if these threads are not machined correctly, or they are not compatible with my tank tee, but getting these threads to stop leaking was a significant challenge. All that being said, this was the only part/supplier selling this part so beggars can't be choosers!

Maybe store them better?

They were packaged OK as usual but the threads were in sorry shape from handling prior to shipping. I had to chase them with my Dremel to even make them go halfway home.

Trash casting

Maybe I've just been unlucky, but this is the second Elkhart copper part I've got from Supply House where the casting has been absolute trash. The start of the thread was missing making it impossible to thread into anything.

I would buy this again if I needed it.

I needed this copper adaptor for the air line I was installing in my garage. The fitting was perfect, and I was happy to find it at Supply House, as they seemed to be the only place who carried it. Unfortunately I only needed one of them, but they were sold only in packages of 5. I would have been willing to pay more for just one of them than the resulting cost from buying a package of 5. Now I have 4 of them that I will probably never need again. They will probably sit unused in my garage until I die.

3/4 inch copper x 1/2 inch NPT copper adapter

The fittings were of high quality. The thickness of the fittings was good. The NPT threads were cut correctly, not too deep, with sufficient taper.

Q: I have a question about this product: 3" Copper X Male Adapter SKU:WP4-48 Brand: Cello I have 3" ID copper pipes with 1/16" wall thickness. Does this product fit inside the 3" ID copper pipe? Outside? Neither (it abuts and needs a slip-slip coupler)? Thanks.

Your pipe will fit inside the WP4-48 . What is your application? The above fitting is a pressure fitting for water piping and is $ 53.88 but if your application is either a plumbing drain or vent the fitting below will do the job and is a little less costly!  SKU: WD84-48 is $ 36.51

A standard plumbing 3" C x MIP Adapter will be 3.125 ID on the copper side. Standard copper pipe will be 3.125 OD and will fit inside the adapter. Based on the type of copper, K, L or M, only the ID changes. The OD does not change and all copper types will fit inside this adapter.

Q: I suppose the street size 3/4" means the tube size that the actual OD size is 7/8". But about the thread size, 1" IPS, does it mean 1" NPT ? Thank you !

The WP4-12-16 copper fitting is designed to fit over nominal 3/4" copper. Since 3/4" copper has a 7/8" OD, the fitting has an ID slightly larger than 7/8". IPS thread is interchangeable with NPT.

IPS refers to iron pipe size, same as NPT. It basically translates 3/4 ID copper X 1" male pipe thread. Sent from my iPhone

IPS stands for Iron Pipe Size. All Iron is NPT or national pipe thread. Hope this helps

3/4" x 1" Copper X Male Adapter IPS means iron pipe size in your case you have 3/4 copper sweat X 1" male adaptor NTP means national pipe tappered ( the thread on the fitting is tappered

Was this review helpful to you?
- Another PexSupply Customer

IPS (Iron Pipe Size) can be Straight or Tapered thread, but generally is considered Tapered unless otherwise stated. NPT (National Pipe Tapered) is Tapered. So, yes, in this case 1" IPS is the same as 1" NPT. FYI, NPSM is the designation for National Pipe Standard Mechanical which is a Straight (non-tapered) thread.

Plumbing sizes are in listed in “ID” and refrigeration sizes are listed in “OD”, the ¾” plumbing size will be 7/8” OD. The word street in plumbing means that the ¾” size will be the same as the pipe OD such as a street ell or street 45. The IPS means Iron Pipe Size and is the same as NPT or National Pipe Thread. Bob

Right: 3/4" copper is 3/4" on the inside, 7/8" on the outside (which means that the copper sweat end of this adapter is 1" in diameter on the outside, since it's a fitting). IPS, NPT, and MIP are all equivalent here, since all modern fittings use NPT for iron pipe size equivalents. Regards, Scott

It means INTERNAL pipe thread...the same tapered pipe thread referred to as NPT Sent from my Verizon Wireless BlackBerry

The outside diameter of copper tubing is 1/8” over the “Call-out” size. International pipe standard and national pipe thread refers to the same standard pipe thread. Also, MPT refers to male pipe thread and FPT refers to female pipe thread No virus found in this message.

I already replied about the thread question...but I think you may be mistaken about the copper sweat end of this fitting.  In my experience if a fitting like this is intended to fit into another fitting (meaning that it measures the same diameter as the copper pipe itself...7/8") then it is referred to 3/4" male fitting x male adaptor...the "male adaptor refers to the threaded end.  The one shown below would  get a copper pipe soldered into it (or the street end of a street 90 for example)...does that make sense?

To my understanding these are made in Canada by a union company. If they are imports you would not be able to tell by the quality.

Q: Does this 1" NPT measure 1" diameter on the inside threads or 1-1/4" It starts getting confusing when some people go by the I.D. and others go by the O.D.

There is no I.D. or O.D. for thread sizes. The thread size is 1" NPT and will connect to any 1" female NPT connection.
