Value Collection BDNA-9987 O-ring Dash 212 Nbr 7/8 in Id

Product Description

The Value Collection BDNA-9987 is a Dash 212 O-ring used to create fluid-tight seals in hydraulic, pneumatic, plumbing, and refrigeration assemblies. It has an inside diameter of 7/8 inches and a cross-section thickness of 1/8 inches. The round cross-section profile seats evenly in standard O-ring grooves. The body is molded from nitrile butadiene rubber (NBR), which resists petroleum-based oils, fuels, and common refrigerants. Plumbers, HVAC technicians, and industrial maintenance trades use NBR O-rings for valve stems, fittings, pump housings, and similar sealing points where oil and water resistance are required.

This O-ring is suited for residential and light commercial plumbing, HVAC refrigerant circuits, hydraulic systems, and general industrial fluid-handling applications. The Dash 212 designation follows the standard AS568 numbering system, making it straightforward to cross-reference against existing groove dimensions. It is sold individually with a minimum order quantity of 25 units, making it appropriate for service stock or bulk replacement applications where multiple sealing points are being serviced at once.

Key Features

• Dash 212 AS568 standard sizing for easy cross-reference and groove compatibility
• 7/8 inch inside diameter fits standard Dash 212 groove specifications
• 1/8 inch cross-section thickness with round profile for consistent seating
• Nitrile butadiene rubber (NBR) material resists petroleum oils, fuels, and water
• Sold in single-unit packaging with a 25-unit minimum order quantity for service stock

Compatibility

Designed as an OEM-style replacement O-ring for any application requiring a Dash 212 standard O-ring in hydraulic, pneumatic, plumbing, or HVAC refrigerant service where NBR material is appropriate.

Installation Notes

Plumbers, HVAC technicians, and hydraulic system technicians typically install O-rings of this type. Always depressurize and isolate the system before removing or installing O-rings. Lightly lubricate the O-ring with a compatible lubricant prior to installation to prevent tearing during seating. Verify the groove dimensions match the Dash 212 specification before installation to ensure a proper seal.
