Tear resistant EPDM rubber thin washers/sealing gaskets

EPDM rubber thin washers are custom sealing parts for interfaces with limited section height. The thin profile should lie flat in the intended seat, with its inner and outer edges supported by the mating geometry. Careful handling helps preserve those edges before the joint is closed.

Avoid dragging the washer across sharp threads or corners during fitting. A small nick can be difficult to see once the seal is installed. The assembly method should keep the part centered rather than stretch it into place. Check the closing gap and ensure that the washer is not folded beneath the adjoining surface.

Select the EPDM formulation for the actual medium and temperature; the material name does not imply compatibility with every fluid. During replacement, clean the seat and inspect for a defect that may have cut the previous washer. A thin gasket should be replaced with the specified thickness and outline rather than stacked or trimmed to accommodate an unexplained difference in the joint.
