1.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.
2.The build-in teeth on the coupling grip the groove shoulder and serve to reduce linear movement.
3.The Tougue & Groove mechanism features a slight offset at the foot of the coupling halves which serve to protect the gasket from exposure.
4.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.
