I had to add a supply valve for my refrigerator in my house. It's my first time working with pex. I added some Pex B to my existing Viega cold water line and used copper crimp rings with the appropriate tool. All of my crimps were checked with a go/nogo gauge.

My concern is that one of the crimps (the bottom one) is slightly off centered from the front as you can see from the image. I have no leaks in the system and it's working great so far, but I was curious if it warrants a re-crimp or if it will hold just fine if it's holding now.

I'd prefer to not have to re-crimp it, because there's only so much extra pex pipe under there and I'd prefer to not add too much complexity by adding another coupling to put some new line in and re-crimp the tee.

Your crimp ring looks good to me as well. It takes a lot of crooked to make a pex fitting leak. I've only managed a leaking pex fitting once, but I'd say if you're more than about 10 degrees off, you risk leaking.

However, for future reference, when I'm working in tight spaces where I'm concerned I might cause a leak, I use sharkbite fittings. While they are expensive, they are easy to add on and do not need a crimp tool. Sometimes it is difficult to get these large crimpers in small spaces and crimp straight. The cost of the fitting is well worth it if you prevent a leak.

As long as the crimp ring is correctly positioned over the brass barbs, you should be fine with it slightly crooked like that.

I don't have a source to back that up though, so maybe I shouldn't have answered.

  • i agree with , Mr Dotes not the worst crimp i have seen. If it was plastic tee maybe. You used a good fitting. – user101687 Jun 25 at 18:25
