Product Description

The compression fittings (brass pex fitting) are among the most popular choices for pex pipe or pex-al-pex pipe systems. This tubing typically features two rubber o-rings positioned over the barbs.

Each fitting includes an insert that fits inside the tubing, a compression ring split diagonally, and a compression nut. The insert resides within the tubing while the compression ring stays on the outside under the compression nut. This unique PEX fitting design does not require specialized tools—simply use a wrench or pliers to tighten the nut over the compression ring. As it tightens, the diagonal cut closes, forming a secure, compressed seal.
