4 900# 316L SS & GRAFOIL RW S/W GA

Built for gasketed flange connections, this 316L Stainless Steel Grafoil Spiral Wound Gasket, 4 inch, Class 900 supports maintenance, replacement, and MRO programs where spiral wound gaskets are specified by material, size, and pressure class. The row-level attributes identify 316L stainless steel construction with Grafoil, Class 900 / 900 lb pressure class, and 4 inch sizing for spiral wound gasket selection in flange maintenance and process piping support. 316L Stainless Steel wording is retained to support spiral wound gasket searches that include metal winding or ring material. The copy supports non-branded search intent around flange gasket selection, gasket kit identification, conduit sealing, and industrial sealing components. Source notes identify Grafoil filler, which has been retained in the generated product context where it helps distinguish the row. The product data identifies size 4 inch, and Class 900 / 900 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. This helps industrial buyers compare gasket options by product type, material family, flange format, and maintenance use case.
