Value Collection BDNA--9977-9 O-ring Dash 028 Nbr

Product Description

The VALUE COLLECTION BDNA--9977-9 is a Dash 028 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 1-3/8 inches inside diameter and 1/16 inch in thickness, conforming to standard inch-series O-ring dimensions. With a durometer rating of 70 Shore A, this O-ring provides firm sealing performance suitable for use with oils, fuels, and hydraulic fluids. It is commonly installed by plumbers, HVAC technicians, and mechanical service professionals in a wide range of static and dynamic sealing applications where NBR compound compatibility is appropriate.

This O-ring is suited for residential and commercial plumbing, HVAC refrigerant and fluid systems, hydraulic assemblies, and general mechanical equipment where a standard Dash 028 inch-series seal is specified. The NBR compound performs reliably in petroleum-based fluid environments. Each package contains one O-ring, with a minimum order quantity of 25 units per order.

Key Features

• Dash 028 standard inch-series O-ring for broad cross-application fitment
• Nitrile Butadiene Rubber (NBR) compound rated for oil, fuel, and hydraulic fluid compatibility
• 1-3/8 inch inside diameter with 1/16 inch cross-section thickness
• 70 Shore A durometer for firm, reliable sealing under compression
• Round cross section for consistent contact and uniform seating in standard O-ring grooves

Compatibility

Designed as a standard inch-series replacement O-ring for plumbing, HVAC, hydraulic, and general mechanical applications specifying a Dash 028 NBR seal with 1-3/8 inch inside diameter and 1/16 inch thickness.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified mechanical technicians. Depressurize and isolate the system before removing the existing O-ring and inspect the groove for damage or debris prior to seating the new seal. Lightly lubricate the O-ring with a compatible fluid or grease before installation to prevent tearing during assembly. Do not overstretch the O-ring during installation, and verify the replacement compound is compatible with the system fluid.
