Value Collection ZBD9977-7X O-ring Nbr Dash 025

Product Description

The VALUE COLLECTION ZBD9977-7X is a Dash 025 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 1.190 inches inside diameter, 1.310 inches outside diameter, and 0.0625 inches (1/16 inch) thick. With a Shore A hardness of 70 and a working temperature range of -40 degrees F to 275 degrees F, this O-ring is suited for sealing applications involving oils, fuels, hydraulic fluids, and water. It is a standard replacement or maintenance seal used by plumbers, HVAC technicians, and mechanical service professionals across a wide range of fluid-handling systems.

This O-ring is appropriate for use in residential and light commercial plumbing, HVAC, and general mechanical assemblies where a Dash 025 NBR seal is specified. Typical applications include pump housings, valve bodies, fitting connections, and fluid manifolds where moderate pressure and temperature cycling are expected. The NBR compound resists petroleum-based fluids and many common refrigerants, making it a practical choice for service work in both wet and refrigeration systems.

Key Features

• Nitrile Butadiene Rubber (NBR) construction resists oils, fuels, and hydraulic fluids
• Dash 025 standard sizing for direct cross-reference and drop-in replacement
• Round cross section ensures consistent sealing contact in standard O-ring grooves
• Shore A hardness of 70 rated Hard for reliable compression under moderate load
• Wide temperature range: -40 degrees F to 275 degrees F for use in hot and cold service environments
• Lightweight at 0.01 pounds for easy handling and bulk stocking

Compatibility

Designed as a standard Dash 025 O-ring replacement for any application requiring a 1.190-inch ID, 1.310-inch OD, 0.0625-inch thick NBR seal in pump, valve, fitting, or manifold assemblies.

Installation Notes

O-rings are installed by plumbers, HVAC technicians, and mechanical service professionals. Before replacing an O-ring, depressurize the system and drain or isolate any fluid. Lightly lubricate the O-ring with a compatible fluid or grease before seating it to avoid tearing during assembly. Inspect the O-ring groove for nicks or debris that could compromise the seal before installation.
