Value Collection BDNA--9977-12 O-ring Dash 032 Nbr

Product Description

The VALUE COLLECTION BDNA--9977-12 is a Dash 032 O-ring with a 1-7/8 inch inside diameter and a 1/16 inch cross-section thickness. Constructed from Nitrile Butadiene Rubber (NBR) with a 70 durometer rating, this O-ring delivers reliable sealing performance in hydraulic, pneumatic, plumbing, and HVAC applications. The round cross-section profile seats evenly in standard O-ring grooves, providing consistent compression and leak-free performance. Licensed plumbers, HVAC technicians, and industrial maintenance professionals rely on NBR O-rings for their strong resistance to petroleum-based fluids, water, and moderate temperatures.

This O-ring is suited for use in fluid handling systems, valve assemblies, pump seals, and pipe fittings where an inch-measurement Dash 032 seal is specified. Its NBR composition makes it a practical choice in plumbing and HVAC environments where contact with oils, fuels, or water is expected. Sold individually, with a minimum order quantity of 25 units per order.

Key Features

• Dash 032 standard sizing: 1-7/8 inch inside diameter, 1/16 inch cross-section thickness
• Nitrile Butadiene Rubber (NBR) construction resists petroleum fluids, water, and common lubricants
• 70 durometer rating provides firm compression with reliable groove seating
• Round cross-section for uniform sealing contact in standard O-ring grooves
• Inch-system dimensions for direct use in standard Dash 032 groove specifications

Compatibility

Designed as a standard inch-series replacement O-ring for any application calling for a Dash 032 NBR O-ring with a 1-7/8 inch inside diameter and 1/16 inch cross-section thickness.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or maintenance mechanics. Always depressurize and isolate the system before removing or replacing sealing components. Lightly lubricate the O-ring with a compatible fluid or grease prior to installation to prevent tearing during assembly. Do not overstretch the O-ring during installation, as permanent deformation will compromise the seal.
