The VALUE COLLECTION BDNA-9359 is a large-diameter O-ring used to create a reliable static or dynamic seal in fluid and pneumatic systems. Manufactured from Nitrile Butadiene Rubber (NBR), it measures 19 inches inside diameter, 25 inches outside diameter, and 2.5 inches thick with a round cross section. NBR compound provides solid resistance to petroleum-based oils, hydraulic fluids, and water, making this O-ring well suited for demanding industrial and mechanical sealing applications. Plumbers, pipefitters, and industrial maintenance technicians are the typical installers.
This O-ring fits large-bore sealing applications in industrial piping, fluid power systems, pumps, and hydraulic equipment where a 19-inch ID round-cross-section seal is required. The metric-dimensioned Nitrile compound suits both industrial and trade environments where oil-resistant elastomers are specified. Each order is sold as a single piece; note that a minimum order quantity of 25 units applies.
Designed as a replacement-style NBR O-ring for large-diameter static and dynamic sealing applications in industrial pumps, hydraulic systems, and fluid piping assemblies requiring a 19-inch ID by 25-inch OD by 2.5-inch thick round-cross-section seal.
Installation should be performed by a qualified plumber, pipefitter, or industrial maintenance technician. Depressurize and drain the system completely before removing the old seal or installing the replacement O-ring. Inspect the gland groove for nicks, corrosion, or debris before seating the new ring, and apply a compatible lubricant to ease installation and prevent rolling. Do not stretch or twist the O-ring during installation, as distortion can compromise the seal.
