Description

The Alpine universal coupling provides a flexible, restrained connection for plain-ended pipes. The wide-tolerance sleeve accommodates OD variation across different pipe materials and the central stop ring ensures equal engagement on both pipe ends. Suitable for buried repair joints, expansion joints and connections where slight axial movement or angular deflection must be accommodated.
