Top Quality Galvanized Pipe Coupling - Pull rod clamps – Grip

Technical Parameter: 【VIEW】

PRODUCT DETAILS

The GRIP-LM pipe coupling including three to four pull rods which can effectively reduce the axial pull strength of pipes. The perfect combination of pull rods and coupling greatly lessen vibration, lower noise as well as provide ideal compensation. Easy and quick installation make GRIP-LM a reliable choice for you.

Suitable for pipes O.D φ304-φ762mm

GRIP-LM only can be used on metal pipes.

GRIP-LM is the deformation of G type, based on GRIP-G to improve better performance of GRIP-G for large pipes outside diameters above 300mm, deleted two anchoring and added three pull rods, which can effectively reduce the axial pull strength of pipes.

The perfect combination of pull rods and couplings greatly lessen vibration, lower noise as well as provide ideal compensation.
