Value Collection BDNA--9977-14 O-ring Dash 034 Nbr

Product Description

The VALUE COLLECTION BDNA--9977-14 is a Dash 034 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 2.125 inches inside diameter and 0.0625 inches in thickness, with a durometer rating of 70 Shore A. NBR compound provides reliable resistance to petroleum-based fluids, making this ring a standard sealing solution across HVAC, plumbing, and general mechanical systems. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of O-ring wherever a dependable static or low-pressure dynamic seal is required at the specified dash size.

This O-ring is suited for residential and light commercial applications involving fluid or gas connections where Dash 034 sizing is specified. Typical use cases include valve bodies, pipe fittings, pump housings, and refrigerant service ports that call for an inch-system NBR seal at the 2.125-inch inside diameter. The 70 durometer hardness balances flexibility and compression resistance for consistent seating across a wide range of mating surfaces and service conditions.

Key Features

• Nitrile Butadiene Rubber (NBR) construction resists petroleum-based oils and hydraulic fluids
• Dash 034 standard sizing for direct drop-in replacement in inch-system applications
• 2.125 inches inside diameter with 0.0625 inch cross section thickness
• Round cross section ensures even compression and consistent sealing contact
• 70 Shore A durometer provides balanced flexibility and resistance to extrusion

Compatibility

Designed as an OEM-style replacement for any inch-system application specifying a Dash 034 NBR O-ring with a 2.125-inch inside diameter and 0.0625-inch cross section thickness.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or mechanical contractors following applicable codes. Depressurize and isolate the system before removing the old O-ring to prevent fluid release. Inspect the gland and mating surfaces for scoring or debris before seating the new ring. Avoid over-stretching the O-ring during installation, as this can reduce sealing integrity and shorten service life.
