Value Collection BDNA-9303 O-ring Nbr 3x7x2 Inch

Product Description

The VALUE COLLECTION BDNA-9303 is a round cross-section O-ring manufactured from Nitrile Butadiene Rubber (NBR), a synthetic elastomer widely used in fluid sealing applications across plumbing, hydraulic, and industrial systems. This O-ring measures 3 inches inside diameter, 7 inches outside diameter, and 2 inches thick. NBR offers reliable resistance to petroleum-based oils, fuels, and water, making it a standard choice for technicians working on fluid handling and sealing assemblies where elastomeric seals are required to maintain pressure integrity.

This O-ring is suited for use in residential and commercial plumbing, hydraulic equipment, pump assemblies, and fluid transfer systems where a large-diameter NBR seal is specified. The round cross-section profile seats predictably in standard O-ring grooves. Minimum order quantity is 50 units, and each package contains 1 piece, making this part appropriate for service shops or contractors maintaining inventory for repeated seal replacement work.

Key Features

• Nitrile Butadiene Rubber (NBR) construction resists petroleum oils, fuels, and water
• 3 inch inside diameter and 7 inch outside diameter for large-format sealing applications
• 2 inch cross-section thickness for deep-groove installations
• Round cross-section profile for consistent seating in standard O-ring grooves
• Metric-dimensioned part suitable for applications specifying metric O-ring sizing

Compatibility

Designed as a standard NBR O-ring replacement for large-diameter sealing applications in plumbing, hydraulic, and fluid transfer equipment requiring a 3 inch ID by 7 inch OD by 2 inch thick round cross-section seal.

Installation Notes

O-ring installation is typically performed by licensed plumbers, hydraulic technicians, or qualified maintenance personnel. Always depressurize and drain the system completely before replacing any O-ring seal. Inspect the mating groove for scoring, corrosion, or debris prior to seating the new O-ring. Do not use sharp tools to seat the O-ring, and avoid overstretching during installation to prevent premature seal failure.
