Anglepad Coupling
Rigid coupling
- The Tougue&Groove mechanism in combination with a slightly shortened key diameter provides a mechanical and frictional interlock resulting in a rigid joint which reduces undesired angular movement.
- The build-in teeth on the coupling grip the groove shoulder and serve to reduce linear movement.
- The Tougue&Groove mechanism features a slight offset at the foot of the coupling halves which serve to protect the gasket from exposure.
- With the Tongue&Groove style coupling no metal-to-metal contact of the bolt pads is required you will normally see a 1.6mm to 3.2mm gap between the bold pads when installed.
