Value Collection BDNA--9984-8 O-ring Dash 130 Nbr

Product Description

The VALUE COLLECTION BDNA--9984-8 is a Dash 130 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 1-5/8 inches inside diameter and 3/32 inches thick, with a durometer rating of 70 Shore A. NBR compound provides solid resistance to petroleum-based fluids, hydraulic oils, and fuels, making this O-ring a standard choice for sealing applications in HVAC, plumbing, and fluid-handling systems. Licensed technicians and tradespeople use this part as a replacement or maintenance seal wherever a Dash 130 O-ring is specified.

This O-ring suits a broad range of residential and commercial applications, including refrigerant line fittings, hydraulic couplings, water valves, and pneumatic connectors. Its inch-system sizing aligns with standard Dash 130 specifications, so it drops into any fitting or groove calling for that designation. HVAC technicians, plumbers, and mechanical contractors will encounter this size frequently in valve bodies, union fittings, and pump housings across both new installation and service work.

Key Features

• Dash 130 standard sizing: 1-5/8 inches inside diameter, 3/32 inches cross-section thickness
• Nitrile Butadiene Rubber (NBR) construction offers resistance to petroleum-based fluids, oils, and fuels
• 70 Shore A durometer provides a firm yet compressible seal suited for moderate-pressure applications
• Round cross section ensures consistent compression and sealing contact across the groove
• Inch-system dimensions match standard Dash 130 O-ring specifications used widely in trade applications

Compatibility

Designed as a standard Dash 130 inch-series O-ring replacement suitable for use in any fitting, valve body, or housing that specifies a Dash 130 NBR O-ring with a 1-5/8 inch inside diameter and 3/32 inch cross-section thickness.

Installation Notes

O-ring installation is performed by HVAC technicians, plumbers, and mechanical contractors during service or new construction. Always depressurize and isolate the system before removing the old O-ring and installing the replacement. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before seating it in the groove to prevent tearing during assembly. Inspect the groove for nicks or debris before installation to ensure a proper seal.
