Value Collection BDNA--9977-2 O-ring Dash 017 Nbr

Product Description

The VALUE COLLECTION BDNA--9977-2 is a Dash 017 O-ring with an 11/16 inch inside diameter and a 1/16 inch thickness. It is molded from Nitrile Butadiene Rubber (NBR) with a round cross section and a 70 durometer hardness rating. NBR provides reliable resistance to petroleum-based fluids, making this O-ring suitable for sealing applications in HVAC, plumbing, and hydraulic systems. Licensed plumbers, HVAC technicians, and mechanical contractors install O-rings of this type during valve, fitting, and pump service work.

This O-ring is sized to the industry-standard Dash 017 designation, which specifies an 11/16 inch inside diameter and a 1/16 inch cross-section thickness in the inch measurement system. It is appropriate for use in residential and light commercial systems wherever a Dash 017 NBR O-ring is required, including refrigerant line fittings, water valves, pump housings, and other fluid-sealing applications that contact petroleum-based or water-based media.

Key Features

• Dash 017 standard sizing: 11/16 inch inside diameter, 1/16 inch thickness
• Nitrile Butadiene Rubber (NBR) material offers broad compatibility with petroleum-based and water-based fluids
• 70 durometer hardness for firm compression sealing under normal operating pressures
• Round cross section ensures uniform sealing contact in standard O-ring grooves
• Inch measurement system sizing for compatibility with standard U.S. fittings and hardware

Compatibility

Designed as a standard Dash 017 replacement O-ring for any application requiring an 11/16 inch ID, 1/16 inch thick NBR O-ring in inch-dimensioned grooves.

Installation Notes

O-rings of this type are installed by licensed plumbers, HVAC technicians, and mechanical service professionals. Always depressurize the system and shut off fluid supply before removing any fitting or valve. Inspect the seating groove for damage or debris before installing the new O-ring. Avoid twisting the O-ring during installation and apply a compatible lubricant to reduce the risk of tearing or improper seating.
