Value Collection BDNA-MP9988 O-ring Dash 213 Nitrile Buna-n

Product Description

The VALUE COLLECTION BDNA-MP9988 is a Dash 213 O-ring made from Nitrile Butadiene Rubber (Buna-N) with a round cross section. It measures 15/16 inches inside diameter and 1/8 inches thick, with a durometer rating of 70 Shore A. This O-ring is used to create static or dynamic fluid seals in hydraulic, pneumatic, plumbing, and HVAC systems. Installation is performed by plumbers, HVAC technicians, and mechanical maintenance professionals working on equipment that requires reliable elastomeric sealing under pressure or temperature cycling. The Buna-N compound provides solid resistance to petroleum-based oils, fuels, and many common refrigerants, making it a practical choice across a wide range of trade applications.

This O-ring is suited for residential and light commercial applications involving water, oil, air, and refrigerant sealing. Common install scenarios include valve stems, pump housings, compressor fittings, pipe unions, and hydraulic cylinder end caps. The Dash 213 designation is a standard sizing reference used across plumbing, HVAC, and industrial fluid-handling equipment, allowing straightforward cross-reference when sourcing replacements. Sold individually with a minimum order quantity of 10 units.

Key Features

• Dash 213 standard sizing for broad cross-reference compatibility
• Buna-N (Nitrile Butadiene Rubber) compound resists petroleum oils, fuels, and many refrigerants
• Round cross section for consistent sealing surface contact
• 70 Shore A durometer provides a balance of flexibility and resistance to extrusion
• Inch-system dimensions: 15/16 inches ID, 1/8 inches thickness

Compatibility

Designed as a standard Dash 213 replacement O-ring for use in plumbing, HVAC, hydraulic, and pneumatic assemblies requiring a 15/16 inch inside diameter nitrile seal. Verify groove dimensions and fluid compatibility before installation.

Installation Notes

Power down or depressurize the system completely before removing any sealed assembly. Lubricate the O-ring lightly with a compatible grease or fluid prior to installation to reduce the risk of tearing during seating. Inspect the groove for nicks, burrs, or corrosion that could compromise the seal. Plumbers and HVAC technicians should follow applicable IPC and IFGC guidelines for the specific system being serviced.
