Value Collection BDNA-9339 O-ring 19in Id 24in Od Nbr

Product Description

The VALUE COLLECTION BDNA-9339 is a large-diameter nitrile butadiene rubber (NBR) O-ring designed for static and dynamic sealing applications across industrial, mechanical, and fluid-system installations. It features a 19-inch inner diameter, 24-inch outer diameter, and a 2-1/2-inch cross-section thickness with a round profile. NBR compound provides reliable resistance to petroleum-based oils, hydraulic fluids, and fuels, making it a practical choice for sealing in demanding service environments. Licensed tradespeople and maintenance technicians working on large-bore equipment, tanks, or piping assemblies will find this O-ring sized for heavy-duty use cases.

This O-ring is suited for use in large mechanical assemblies, industrial fluid systems, pump housings, or tank covers where a robust, chemical-resistant seal is required. The round cross-section profile seats cleanly into standard O-ring grooves of the appropriate size. It is applicable in both residential and commercial settings where large-diameter gasketing or sealing components are needed, including plumbing, HVAC equipment bases, and pool or water-treatment system housings.

Key Features

• 19-inch inner diameter and 24-inch outer diameter for large-bore sealing applications
• 2-1/2-inch round cross-section for positive groove seating and compression seal
• Nitrile butadiene rubber (Buna-N) compound resists petroleum oils, hydraulic fluid, and fuels
• Round cross-section geometry for compatibility with standard O-ring groove profiles
• Sold individually per package (minimum order quantity of 50 units)

Compatibility

Designed as a general-purpose replacement O-ring for large-bore sealing applications where a 19-inch ID by 24-inch OD by 2-1/2-inch thick Buna-N round cross-section O-ring is specified.

Installation Notes

Installation should be performed by a qualified technician familiar with sealing and gasketing procedures. Depressurize and fully drain the system before removing the existing O-ring or installing a replacement. Inspect the groove for nicks, corrosion, or debris before seating the new O-ring, and apply a compatible lubricant to ease installation and prevent pinching. Do not overstretch the O-ring during installation, as deformation can compromise the seal.
