CGR – Caulked and Gasketted Recess Plates
These are recess plates with groves on the bearing surface in which a gasket fits. Below the gasket grove on the bearing surface itself, there is another grove in which the cloth is fitted through a chord. The gaskets of one plate seal onto the bearing surface of another thus providing a leak proof solution. Also since the cloth is fixed onto the plate through the grove, it does not extend onto the bearing surface at the bottom thus aiding to the leakproof design as minor seepages do not occur.
