Application

Flexible coupling for grooved pipe steel. High resistance to bending and twisting. It works like an expansion joint, allows the linear movement and angular, the attenuation of noise and vibration, thermal expansion and seismic stress (for these two cases, please pay attention to the support system used).

For the right choice of the gasket, please take a look to selection "GASKET FOR COUPLINGS".
