Value Collection BDNA--9995-3 O-ring Dash 207 Nbr

Product Description

The VALUE COLLECTION BDNA--9995-3 is a Dash 207 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 9/16 inches in inside diameter and 1/8 inches in thickness, conforming to standard inch-series O-ring dimensions. With a durometer rating of 70, it provides firm sealing force suitable for moderate-pressure fluid and pneumatic service. NBR compound offers reliable resistance to petroleum-based oils, fuels, and hydraulic fluids, making it a go-to sealing element for plumbing, HVAC, and general mechanical assemblies where hydrocarbon exposure is expected.

This O-ring is commonly used in residential and light commercial plumbing fittings, HVAC refrigerant circuit components, hydraulic connections, and pneumatic assemblies. Technicians install it wherever a standard Dash 207 inch-series O-ring is called for, including face-seal fittings, valve stems, pump housings, and pipe unions. Its NBR material is well suited for water, air, and oil service within typical operating temperature ranges for that compound. It is sold individually per package with a minimum order quantity of 25 units.

Key Features

• Dash 207 standard sizing: 9/16 inches inside diameter, 1/8 inches cross-section thickness
• Nitrile Butadiene Rubber (NBR) construction for resistance to petroleum oils, fuels, and hydraulic fluids
• Round cross section for consistent seating and even compression in standard O-ring grooves
• 70 durometer hardness for firm sealing with controlled deformation under load
• Inch-series dimensioning compatible with standard Dash 207 groove specifications

Compatibility

Designed as an OEM-style replacement or service O-ring for any application requiring a standard Dash 207 inch-series NBR O-ring in plumbing, HVAC, hydraulic, or pneumatic systems.

Installation Notes

O-ring replacement is performed by licensed plumbers, HVAC technicians, or qualified mechanics depending on the system involved. Always depressurize and isolate the system before removing the old O-ring. Lightly lubricate the O-ring with a compatible fluid or grease prior to installation to prevent tearing during assembly. Do not overstretch or pinch the O-ring during installation, as this can compromise the seal and lead to premature failure.
