“I ordered a bag of these connectors and was very surprised at the amount of quality that these connectors were made to. Unfortunately I had to return them because although they fit perfectly in my Pex tubing, they didn’t fit tight enough into my old polybutylene that was my existing plumbing. It’s not the fault of the connectors, it is because of the 35 year old polybutylene tubing that was in my attic in about 165°F temperatures from here in South Florida. Very high quality, don’t hesitate to purchase them.”
