The VALUE COLLECTION BD-C30593 is a Buna-N nitrile butadiene rubber O-ring designed for static and dynamic sealing applications across plumbing, hydraulic, pneumatic, and industrial fluid systems. With a 10-inch inner diameter and a 3-inch cross-section thickness, this is a large-format seal suited for flanged connections, large-bore fittings, pump housings, and valve bonnets. The round cross-section profile ensures consistent compression and reliable sealing contact. Nitrile rubber provides strong resistance to petroleum-based oils, fuels, and water, making it a common choice for HVAC, plumbing, and industrial service work.
This O-ring is appropriate for use in residential and commercial applications where large-diameter sealing is required. Typical installations include pump flanges, large valve assemblies, filter housings, and equipment access covers. The Buna-N compound performs well in moderate-temperature environments and is compatible with a wide range of hydraulic fluids and water-based media. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers of seals in this size range.
Designed as an OEM-style replacement or service seal for large-diameter flanged connections, pump housings, valve assemblies, and filter housings in plumbing, HVAC, and industrial fluid systems where a 10-inch ID Buna-N O-ring is specified.
Installation should be performed by a licensed plumber, pipefitter, or qualified mechanic following applicable IPC or system-specific service procedures. Depressurize and isolate the system before replacing any seal. Lubricate the O-ring with a compatible grease prior to seating to prevent tearing during installation. Inspect the groove and mating surfaces for damage or debris before fitting the new seal.
