GASKET, 60 DURO BUNA-N, 4.000" 300# FF

This Buna-N / Nitrile Full Face FF Flange Gasket, 4 inch, Class 300, 1/8 inch Thick provides a product-specific full face flange gasket option for plant maintenance, fluid handling equipment, and reseller catalog programs. The row attributes combine Buna-N / Nitrile / NBR material, FF flange gasket terminology, Class 300 / 300 lb pressure class, 4 inch size, and 1/8 inch thickness for clearer gasket sourcing. Buna-N, Nitrile, and NBR wording are used together where helpful because buyers may search using any of those common material terms. Common use cases include pipe flanges, gasketed flange connections, equipment maintenance, plant operations, fluid handling systems, and planned replacement programs. Source notes identify NPS, 0.125 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 300 / 300 lb pressure class. This helps industrial buyers compare gasket options by product type, material family, flange format, and maintenance use case.
