Value Collection BDNA--9977-10 O-ring Dash 030 Nbr

Product Description

The VALUE COLLECTION BDNA--9977-10 is a Dash 030 O-ring with a 1-5/8 inch inside diameter and a 1/16 inch cross-section thickness. It is molded from Nitrile Butadiene Rubber (NBR) with a 70 durometer hardness rating, giving it solid resistance to petroleum-based fluids, oils, and hydraulic media. The round cross-section profile seats evenly in standard O-ring grooves. This part is sold individually and is commonly installed by plumbers, HVAC technicians, and mechanical service techs working on fluid-handling systems.

This O-ring is suited for static and dynamic sealing applications in residential and light commercial systems. Typical uses include sealing pump housings, valve bodies, fittings, and fluid line connections where petroleum-based or water-based media are present. The NBR compound performs across a broad service temperature range, making it a reliable choice for HVAC refrigerant-adjacent components, plumbing connections, and general mechanical assemblies that require an inch-system Dash 030 seal.

Key Features

• 1-5/8 inch inside diameter fits standard Dash 030 groove dimensions
• 1/16 inch cross-section thickness with round profile for consistent seating
• Nitrile Butadiene Rubber (NBR) compound resists oils, fuels, and hydraulic fluids
• 70 durometer hardness balances flexibility with compression resistance
• Inch-system measurement standard for compatibility with US-dimensioned components

Compatibility

Designed as a standard inch-series Dash 030 O-ring replacement for use in pumps, valves, fittings, and other fluid-handling components requiring a 1-5/8 inch ID NBR seal.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified mechanical service personnel. Shut off all fluid supply and relieve system pressure before replacing any O-ring. Lightly lubricate the O-ring with a compatible fluid or grease prior to seating to prevent tearing during assembly. Do not roll or twist the O-ring into the groove; seat it evenly to ensure a proper seal.
