*4" 150# 316 SS & GRAPHITE RWI

This 316L Stainless Steel Graphite Spiral Wound Gasket with Inner Ring, 4 inch, Class 150 is designed for industrial flange sealing applications that call for a spiral wound gasket construction with clearly identified metal and filler materials. The inner ring configuration, 316L stainless steel construction, graphite filler, Class 150 / 150 lb pressure class, and 4 inch sizing make the product clear for spiral wound gasket selection and replacement programs. 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 316L S.S. INNER RING - C/S OUTER S/W; graphite 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 150 / 150 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.
