APV SPX FLOW H77303 Seal

APV SPX FLOW H77303 Seal FGN1 DN50 is an EPDM gasket replacement designed to fit APV SPX Flow DN50 valve assemblies, and it is listed as the H77303 seal type that corresponds to OEM part 58-32-427/93. This DN50 component uses the FGN1 sealing profile and is specified for use with APV SPX Flow equipment in SPX Flow instruction manuals; the DN50 designation confirms a 50 mm nominal bore compatibility with the valve geometry. Documented references in SPX Flow manuals identify H77303 as a DN50 FGN1 seal, aligning with the DN50 flange arrangement used in these valve kits and ensuring reliable leak-tight performance when installed as part of a seal replacement. The sealing compound is EPDM, a material commonly chosen for its elasticity and resistance to typical process fluids in APV/SPX Flow systems, making it suitable for a range of process applications that rely on robust gasket performance at DN50 size. Replacement seals like H77303 are distributed by authorized APV/SPX Flow parts networks and aftermarket suppliers under the APV SPX Flow catalog, with OEM mappings to 58-32-427/93 and compatible DN50 seal kits; in some listings, packs of multiple H77303 seals (e.g., pack of 4) are offered to support service intervals.
