This pipe coupling is a perfectly reliable element designed for connecting thin-wall and thick-wall pipes, both metal and of other materials. Approved by DVGW, IACS, Bureau Veritas, Class NK, Lloyds Register, DNVGL, RINA, Korean Register, ABS, Russian Maritime Register of Shipping, China Classification Society.
- Alternative to conventional pipe connections
Pipe couplings are a cost-effective alternative to conventional pipe connecting methods for both plastic pipes and metal pipes.
- Leak-tight connection
Patented sealing system provides even tighter seal when the pressure of the medium rises. The seal does not deform under pressure thanks to the special compensating design and wedge-shaped lip. The couplings remain tight even under conditions of slight misalignment or angular deflection of pipe axes up to 2°.
- Easy-to-use even in confined spaces
Couplings are lightweight, compact and handy so they can be easily assembled in a restricted space.
- Fast and easy assembly
All plain pipes can be connected fast and easily. The coupling comes pre-assembled, ready-to-fit. It is just pushed over the pipe end, aligned and adjusted to any radial position. For proper and safe assembly tighten the bolts alternately with a torque spanner.
- Effectively dampen pressure variations, vibrations, acoustic waves
