Value Collection ZBD9977-8X O-ring Dash 027 Nbr

Product Description

The VALUE COLLECTION ZBD9977-8X is a Dash 027 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 1.31 inches inside diameter, 1.44 inches outside diameter, and 0.0625 inches thick. With a Shore A hardness of 70 and a working temperature range of -40 degrees F to 275 degrees F, this O-ring provides reliable sealing in hydraulic, pneumatic, plumbing, and HVAC applications. Licensed tradespeople and maintenance technicians use this part as a static or dynamic seal in fluid and air systems where NBR compound compatibility is appropriate.

This O-ring suits residential and commercial applications involving petroleum-based fluids, water, and many common refrigerants where NBR material is chemically compatible. It is a standard Dash 027 size, commonly used in valve bodies, fittings, manifold connections, pump housings, and other sealing points found in plumbing, HVAC, and hydraulic assemblies. Each package contains one O-ring. Minimum order quantity is 25 units.

Key Features

• Nitrile Butadiene Rubber (NBR) construction for resistance to petroleum-based fluids and water
• Dash 027 standard sizing: 1.31 inches ID, 1.44 inches OD, 0.0625 inches thick
• Shore A hardness of 70 rated as hard for stable compression set performance
• Wide working temperature range of -40 degrees F to 275 degrees F
• Round cross section for consistent sealing contact in standard O-ring grooves

Compatibility

Designed as a standard Dash 027 O-ring replacement for any fitting, valve, or assembly that accepts a 1.31-inch ID NBR O-ring with a 0.0625-inch cross section.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. Always depressurize and drain the system before replacing any O-ring to prevent injury or fluid release. Inspect the seating groove for nicks or corrosion before installation, and apply a compatible lubricant to ease seating without rolling or twisting the O-ring. Confirm that the replacement compound is chemically compatible with the system fluid before installation.
