MODEL XGQT4 PUSH-ON COUPLING The Lede Model XGQT4 PUSH-ON rigid coupling is a truly rigid grooved pipe coupling which, unlike other grooved couplings, does not allow for any axial movement, angular movement and or rotational movement under normal service conditions. Lede push-on coupling (patent pending) allows the pipe to move into the couplings directly without loosing components. Support and hanging reguirements correspond to ANSI B31.1, B31.9 and NFPA 13. Caution: Pipe ends must be cut square so that the pipe ends but together. Applications: Sizes available: 32mm-200mm / 1-1/4’’~8’’ Working Pressure: Up to 20 bar / 300 psi
