Value Collection BDNA-9331 O-ring Nbr 11x16x2.5 Inch

Product Description

The VALUE COLLECTION BDNA-9331 is a round cross-section O-ring manufactured from Nitrile Butadiene Rubber (NBR). It measures 11 inches inside diameter, 16 inches outside diameter, and 2.5 inches thick. NBR compounds offer dependable resistance to petroleum-based fluids, hydraulic oils, and fuels, making this O-ring a standard sealing element in fluid-handling and mechanical assemblies. Plumbers, pipefitters, hydraulic technicians, and industrial mechanics install this style of O-ring as a static or dynamic seal in flanges, cylinder bores, valve bonnets, and similar applications requiring a robust elastomeric gasket.

This O-ring is suited for use in large-bore sealing applications across residential, commercial, and light industrial settings. Typical install scenarios include pump housings, large-diameter pipe flanges, hydraulic cylinder end caps, and valve assemblies where a round cross-section NBR seal is specified. The 2.5-inch cross-section thickness provides substantial material for compression sealing in wide gland grooves. Minimum order quantity is 50 pieces; each package ships as a single unit.

Key Features

• Nitrile Butadiene Rubber (NBR) construction resists petroleum-based fluids, hydraulic oils, and fuels
• Round cross-section profile for use in standard O-ring gland grooves
• 11 inch inside diameter and 16 inch outside diameter suit large-bore sealing applications
• 2.5 inch cross-section thickness provides generous compression range in wide gland designs
• Metric-dimensioned part suitable for metric-specified assemblies and equipment

Compatibility

Designed as an OEM-style replacement or maintenance seal for large-bore static and dynamic sealing applications requiring a round cross-section NBR O-ring with an 11 inch inside diameter and 16 inch outside diameter.

Installation Notes

Installation is performed by qualified plumbers, pipefitters, or hydraulic technicians following applicable codes and equipment manufacturer procedures. Depressurize and drain any fluid system fully before removing or installing seals. Inspect the gland groove for burrs, corrosion, or wear before seating the O-ring, and apply a compatible lubricant to ease installation and reduce the risk of tearing the elastomer during assembly. Do not overstretch the O-ring during fitment.
