Felt is a versatile material with cushion, resilience under pressure and its ability to seal out dust. Pressed wool felt is highly absorbent and remains uninjured by oil saturation. Industrial felt gaskets are available in SAE felts, Mil-spec felts, F-series felts (grades from White F1 felt to Grey F7) and in a variety of mechanical felts. We also supply MiI-spec grade for military applications. Temperature ranges are typically: -4°F to 100°F.
