GASKET, SMOOTH RED RBR, 4.000" 300# FF

Built for gasketed pipe flange connections, this Smooth Red Rubber Ring Face RF Flange Gasket, 4 inch, Class 300, 1/16 inch Thick supports industrial sealing, maintenance, and replacement programs where dimensional clarity is important. The gasket is defined by smooth red rubber construction, ring face / RF geometry, Class 300 / 300 lb pressure class, 4 inch sizing, and 1/16 inch thickness for industrial flange sealing applications. Red rubber wording is included because many buyers search for rubber flange gaskets by material, finish, face style, and thickness. The copy supports non-branded search intent around flange gasket selection, gasket kit identification, conduit sealing, and industrial sealing components. Source notes identify NPS, 0.062 THK, which has been retained in the generated product context where it helps distinguish the row. The product data identifies size 4 inch, thickness 1/16 inch, and Class 300 / 300 lb pressure class. The product details help buyers connect the part to common searches for flange gaskets, gasket kits, industrial gasket materials, and maintenance replacement components. Item 13880FF062B0400FC is included to distinguish this product from similar gasket rows with close material, size, and class attributes.
