The VALUE COLLECTION BDNA-9305 is a nitrile butadiene rubber (NBR) o-ring with a round cross section, sized at 5 inches inside diameter, 9 inches outside diameter, and 2 inches thick. NBR is a synthetic rubber compound widely used in fluid-handling applications where resistance to petroleum-based oils, hydraulic fluids, and fuels is required. This o-ring is used to create static or dynamic seals in mechanical assemblies and fluid system connections. Installation is typically performed by plumbers, pipefitters, hydraulic technicians, and industrial maintenance mechanics working on pumps, valves, cylinders, and manifold systems.
This o-ring is suited for use in residential and commercial plumbing, hydraulic systems, pneumatic assemblies, and general industrial fluid-handling equipment. Its large diameter makes it appropriate for sealing wide-bore fittings, pump housings, valve bonnets, and similar large-format connections. The NBR material performs reliably in applications involving water, oil, and many common hydraulic fluids. This part is sold individually with a minimum order quantity of 50 units per order.
Designed as an OEM-style replacement or service seal for large-bore fluid system components requiring a 5 inch ID by 9 inch OD by 2 inch thick round cross section NBR o-ring.
Depressurize and drain the system fully before removing the existing seal or disassembling the joint. Clean the groove and mating surfaces of all debris, old sealant, and residue before seating the new o-ring. Lubricate the o-ring with a fluid compatible with both NBR rubber and the system medium prior to installation to prevent tearing during assembly. Follow applicable plumbing or mechanical codes for the jurisdiction and system type.
