I am looking for something like this, but for polyethylene tubing. Do you know of such a product?
gray c on Jun 15, 2012
BEST ANSWER: I am not sure why you would need this for poly. This is used on pvc when you have a break in a straight run of pipe. With PVC there is no way to spread the broken ends apart to get the fitting in to repair it. This solves that problem.

With Poly, you have enough flex to put a double nipple connector in. If the line does not come together you would need to cut enough out that you can use two double nipple connecters with a new piece of poly in between.

This is a link to the double nipple fitting I am talking about.


I probably don't understand your application but this seems like what you are trying to do.
Will this work for pool plumbing repairs?
Robert Z on Apr 15, 2015
BEST ANSWER: I had difficulty with the INT-1112 connector and it failed because I did not follow the instructions precisely (glue end, lock in place and do it quickly). I only had one so I couldn't re-do it.

I replaced it with the CPC-1500 (King Brothers) unit which was much easier to install but compression fittings must be ABSOLUTELY rigid because if it wiggles, the compression fails. Tne irrigation system gets up to about 50# so I am not sure what pool systems require.

Moral of the story, compression fittings are great, easy to install and do not require glue. Again just make sure the pipe is straight and does not wiggle.

What is the length of your 1 1/2" slip repair INT-1112?
A shopper on Nov 26, 2015
BEST ANSWER: I've since thrown away the header card but I believe the cutout was about 6 1/2". The final repair end-to-end is about 10" long.
