Elkhart Products 102 1" 1-Inch Copper by Copper Unions

Fast delivery, great price compared to big box stores, installed and worked well.

Just what I needed!!~

I have installed all types of plumbing unions for many years, although I am not a Pro, just an advanced homeowner. This is the first one I ever installed that had a leak, although extremely slight within the union itself. I had 2 6 inch stubs already soldered in to the union before i put the assembly in place. I had the union snugged up just a touch more than hand tight to make sure the alignment was correct before placing the assembly in and sweat soldering it into place. The union leaked like a drop every 30 seconds or so even though it was tightened sufficiently. Before I even went to use the union at all, I had looked at the parts to make sure the finishes of the mating parts looked good, and they did. I drained the system, used some Permatex RTV gasket maker according to the package instructions and let it cure for 24 hours before letting water into the system again, and it was fine. I would have given it 5 stars otherwise because it looks very well made, but I cannot. Maybe mine was defective, but it looked fine without using any instruments.

Good price - doesn't leak. There isn't too much else to say but it seems like decent quality and the ones at the box stores have less than stellar reviews.

Purchased 4 1" units for a main line water filter project I built on the bench. Cut in and pressurized all 4 leaked steady drip. Made miltiple attempts to reseat, add teflon tape etc. Closer inspection of parts showed male faces not good.

Excellent quality. Leak free seal on the first try, which can be a trick if the surface is not perfect.

Exactly what I needed high quality copper union. Thank you! :)

if you are installing filters that screw in, you will need one on each end . no leaks!
