Abstract
The disclosed principles provide for novel flange gaskets having a mesh filter and methods of manufacture thereof. Disclosed mesh flange gaskets provide a combination of quality seal, even at low clamp loads, with a filter for filtering out unwanted particulates, as well as manufacturing at a low cost. In one aspect, the disclosed principles utilize expanded PTFE, or other similar sealing material, on the outer section of a circular mesh positioned over the central bore of the flange and which is sandwiched between the two halves of a corrugated plastic gasket. The two halves of the flange gasket are then attached to each other with the ePTFE impregnated mesh therebetween. With this composition, the ePTFE impregnated mesh becomes part of the seal of the overall flange gasket. This provides low load sealing on the top and bottom of the gasket against the flanges, and prevents leakage through the middle barrier layer.
