Value Collection ZBD9976 O-ring Nbr Dash 011 0.313 Id

Product Description

The VALUE COLLECTION ZBD9976 is a Dash 011 O-ring made from Nitrile Butadiene Rubber (NBR), designed for static and dynamic sealing applications across HVAC, plumbing, and fluid-handling systems. It features a round cross-section profile with an inside diameter of 0.313 inches, an outside diameter of 0.437 inches, and a thickness of 0.0625 inches. With a Shore A hardness of 70 and a working temperature range of -40 degrees F to 275 degrees F, this O-ring handles common refrigerants, oils, water, and hydraulic fluids without degrading under normal service conditions. Licensed technicians and plumbers install this seal during equipment service, valve repair, and fitting replacement.

This O-ring is suited for residential and light commercial HVAC equipment, plumbing valves, pump assemblies, and fluid-line fittings where a standard Dash 011 NBR seal is specified. The NBR compound offers solid resistance to petroleum-based fluids and moderate-pressure service conditions, making it a go-to replacement seal for service technicians working across refrigeration circuits, water supply lines, and hydraulic assemblies. It is sold individually and requires a minimum order quantity of 50 units per order.

Compatibility

Designed as an OEM-style replacement O-ring for any application specifying a Dash 011 NBR seal in HVAC, plumbing, pump, or fluid-handling equipment.

Installation Notes

O-ring installation should be performed by a qualified HVAC technician or licensed plumber following system depressurization and fluid isolation. Lightly lubricate the O-ring with a compatible lubricant before seating it into the groove to prevent nicking or rolling during assembly. Do not stretch the O-ring over sharp edges, and inspect the seating groove for burrs or corrosion before installation. Follow applicable codes including IFGC or IPC requirements when replacing seals in gas or potable water systems.
