PE pipe compression fittings, designed specifically for use with polyethylene piping, offer a uniquely practical joining solution that stands apart from thermal fusion methods by providing a secure, mechanical connection achievable with nothing more than common hand tools. This clever separation of gripping and sealing functions is what gives PE pipe HDPE compression fittings fittings their remarkable reliability, as the mechanical grip does not rely on the seal's integrity to prevent pull-out, and the seal is not compromised by the biting action of the gripper. The installation of PE pipe with compression fittings is remarkably swift and straightforward, making these components a favorite among maintenance crews and contractors who need to complete jobs quickly and without the logistical burden of heavy equipment. The fitting is then disassembled, the nut and gripper are slid over the pipe end, and the pipe is pushed firmly into the fitting body until it seats against the internal shoulder.
