PE Compression Equal Coupling

PE Compression Equal Coupling is a straight, tool-free connector used to join two lengths of polyethylene (PE) pipe of the same outer diameter. Unlike PPR or PPH fittings, which rely on heat fusion, this fitting uses a compression mechanism: the pipe is inserted into the fitting body, and a threaded nut is tightened to compress an internal grab ring and O-ring seal against the pipe surface, forming a seal without welding, gluing, or specialized equipment.
This connection method makes PE compression fittings a practical choice for field installation, where access to fusion welding equipment may be limited or impractical, or where the installer needs the flexibility to assemble and, if necessary, disassemble the joint later. The equal coupling is the most basic fitting in this range, used simply to extend or join two same-diameter pipe sections in a straight line.
