The compression fittings (brass pex fitting) are among the most popular fittings for PEX pipe or PEX-AL-PEX pipes. This tubing usually comes with two rubber O-rings positioned over the barbs. Each fitting includes an insert that goes inside the tubing, a compression ring that is split diagonally, and a compression nut.
The insert goes inside the tubing and the compression ring on the outside with the compression nut over it. This is the only form of PEX fitting that does not require special compression tools. All you have to do is use a wrench or pliers and tighten the nut over the compression ring. As the ring is tightened, the diagonal cut closes, forming a secure compressed ring.
