Value Collection BDNA-9360 O-ring 20 in Id 26 in Od Nbr

Product Description

The VALUE COLLECTION BDNA-9360 is a large-diameter Nitrile Butadiene Rubber (NBR, also known as Buna-N) O-ring with a round cross section. It measures 20 inches inner diameter, 26 inches outer diameter, and 3 inches thick. NBR is a synthetic rubber compound well-suited for sealing applications involving petroleum-based fluids, hydraulic oils, water, and many common industrial fluids. This O-ring is used by plumbers, pipefitters, millwrights, and industrial maintenance technicians wherever a large-format static or low-dynamic seal is required. Its robust construction and proven material compatibility make it a dependable choice for demanding sealing environments.

This O-ring is appropriate for large-diameter pipe flanges, tank covers, pump housings, valve bodies, and similar industrial or commercial sealing applications. Its 3-inch cross-section thickness provides substantial compression area for achieving reliable seals on wide-face grooves and glands. Minimum order quantity is 25 units, and each unit is packaged individually.

Compatibility

Designed as a large-diameter NBR O-ring replacement suitable for industrial pump housings, valve bodies, tank covers, and pipe flange assemblies requiring a 20-inch ID, 26-inch OD, 3-inch cross-section seal groove.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or industrial maintenance technician. Before installing, de-pressurize and fully drain the system, and ensure all mating surfaces are clean and free of debris or old sealant. Lubricate the O-ring with a compatible fluid or O-ring lubricant prior to seating to prevent tearing during compression. Do not overstretch or twist the O-ring during installation, as distortion can cause premature seal failure.
