Graco 622142 Seal, Piston

The Graco 622142 Seal, Piston is an essential part to prevent leaks while at the same time ensuring correct operation in using Graco spray painting equipment. In other words, it’s a specialized seal that goes around the piston in the pump and keeps a tight and reliable seal. The common seal is normally created from a heavy duty as well as flexible product like polyurethane or nitrile rubber. The seal, in this case, is constantly compressed and expanded as it moves with the piston, in and out of the cylinder. The betterness of this prevents air or fluid from getting pushed past the piston making the pump functional and efficient.
