GASKET, CLOTH RED RBR, 4.000" 150# FF

This Fabric-Finish Red Rubber Full Face FF Flange Gasket, 4 inch, Class 150, 1/8 inch Thick is made for full face flange applications where the gasket must cover the flange face and align with the specified size, material, pressure class, and thickness. The fabric-finish red rubber material, FF full face geometry, Class 150 / 150 lb pressure class, 4 inch size, and 1/8 inch thickness support gasket selection for full face pipe flange connections. Red rubber wording is included because many buyers search for rubber flange gaskets by material, finish, face style, and thickness. For buyers comparing similar products, the material, size, face style, class, and thickness details help narrow the selection without adding unsupported compatibility claims. Source notes identify NPS, .125" THK, which has been retained in the generated product context where it helps distinguish the row. The product data identifies size 4 inch, thickness 1/8 inch, and Class 150 / 150 lb pressure class. Use it for replacement gasket programs, MRO stocking, reseller catalog enrichment, and product pages that need non-branded search terms without relying on unsupported performance claims.
