Value Collection BDNA--9985-1 O-ring Dash 117 Nbr

Product Description

The VALUE COLLECTION BDNA--9985-1 is a Dash 117 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 13/16 inches inside diameter and 3/32 inches in thickness, with a durometer hardness rating of 70. NBR compounds offer reliable resistance to petroleum-based fluids, making this O-ring well suited for sealing applications in HVAC, plumbing, and fluid-handling systems. Licensed technicians and plumbers rely on this standard inch-series O-ring for maintenance, repair, and replacement tasks where a durable, chemically compatible seal is required.

This O-ring is appropriate for use in residential and light commercial applications including refrigerant line fittings, pump seals, valve bodies, and hydraulic or pneumatic connections where NBR material compatibility is confirmed. The Dash 117 designation follows the standard AS568 O-ring sizing series, allowing straightforward cross-reference to equivalent parts. It is sold individually with a minimum order quantity of 50 units, making it practical for stocking in a service van or shop inventory.

Key Features

• Dash 117 standard AS568 sizing for easy cross-reference and replacement
• 13/16 inch inside diameter and 3/32 inch thickness with round cross section
• Nitrile Butadiene Rubber construction rated at 70 durometer for firm, consistent sealing
• NBR compound provides resistance to petroleum-based oils and hydraulic fluids
• Inch-system dimensioning compatible with standard North American fittings and valve hardware

Compatibility

Designed as an OEM-style replacement O-ring for applications requiring a Dash 117 inch-series NBR seal in HVAC, plumbing, or fluid-handling equipment.

Installation Notes

O-ring replacement is performed by licensed plumbers, HVAC technicians, or qualified mechanics depending on the application. Always depressurize and isolate the system before removing the old O-ring to prevent injury or fluid release. Lightly lubricate the new O-ring with a compatible fluid before installation to prevent tearing during assembly. Confirm material compatibility with the system fluid before installing an NBR O-ring in applications involving non-petroleum-based chemicals.
