Value Collection BDNA-9308 O-ring 8x12x2 Inch Nbr

Product Description

The VALUE COLLECTION BDNA-9308 is a round cross-section O-ring manufactured from Nitrile Butadiene Rubber (NBR), a synthetic elastomer widely used in fluid and pneumatic sealing applications. With an 8-inch inside diameter, a 12-inch outside diameter, and a 2-inch thickness, this is a large-format sealing ring suited for industrial and commercial service work. NBR offers solid resistance to petroleum-based oils, hydraulic fluids, and fuels, making it a practical choice where hydrocarbon exposure is expected. Licensed plumbers, pipefitters, and industrial mechanics typically install O-rings of this size during pump, valve, and manifold service.

This O-ring is appropriate for large-diameter sealing applications in commercial plumbing, hydraulic systems, pump housings, and industrial fluid-handling equipment. Its metric-system dimensions and round cross-section profile make it compatible with standard metric groove specifications. Technicians working on large centrifugal pumps, filter housings, or flanged assemblies will find this size relevant for static sealing applications where a face or radial seal is required.

Key Features

• 8-inch inside diameter for large-bore sealing applications
• 12-inch outside diameter with a 2-inch cross-section thickness
• Nitrile Butadiene Rubber (NBR) construction for resistance to petroleum oils and hydraulic fluids
• Round cross-section profile seats reliably in standard O-ring grooves
• Metric-dimensioned for compatibility with metric groove specifications

Compatibility

Designed for use in large-diameter static sealing applications including pump housings, valve bodies, filter bowls, and flanged industrial fluid-handling assemblies where NBR material is appropriate for the media present.

Installation Notes

Shut down and de-pressurize the system fully before removing any sealed component. Inspect the mating groove for burrs, corrosion, or damage before seating the O-ring. Lubricate the O-ring lightly with a compatible fluid or grease to ease installation and prevent rolling or twisting during assembly. Follow applicable mechanical or plumbing codes for the system type being serviced.
