Value Collection BD-9301 Nbr O-ring Round Cross Section

Product Description

The VALUE COLLECTION BD-9301 is a Nitrile Butadiene Rubber (Buna-N) O-ring with a round cross section, designed for sealing applications across plumbing, HVAC, and fluid-handling systems. Buna-N is the standard elastomer for petroleum-based fluid service and delivers reliable resistance to oils, fuels, and common refrigerants in moderate-temperature environments. This O-ring is sold individually and is suitable for use wherever a round-section NBR seal is required for maintenance, repair, or new installation work.

The BD-9301 is appropriate for residential and light commercial applications involving hydraulic connections, threaded fittings, flanged joints, and valve seats. Typical install scenarios include refrigerant service port seals, water shutoff valve seats, and general fluid-line connections serviced by HVAC technicians, plumbers, and pipefitters. Its compact form factor makes it a standard consumable for service trucks and shop inventory.

Key Features

• Buna-N (Nitrile Butadiene Rubber) material offers solid resistance to petroleum-based oils, fuels, and many refrigerants
• Round cross section provides consistent radial sealing contact on standard O-ring grooves
• Lightweight at 0.01 pounds, suitable for tight-clearance fittings and compact assemblies
• Sold as a single unit, allowing precise quantity procurement for service and repair

Compatibility

Designed as an OEM-style replacement seal for standard O-ring groove applications in plumbing, HVAC, and fluid-handling equipment requiring a Buna-N round cross section elastomer.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or pipefitters as part of valve, fitting, or flange service. Always depressurize and isolate the system before removing or replacing any O-ring seal. Lightly lubricate the O-ring with a compatible lubricant before seating to prevent tearing during assembly. Inspect the groove for damage or debris before installing the new seal.
