Value Collection ZBD9977-15 O-ring Nbr Dash 036

Product Description

The VALUE COLLECTION ZBD9977-15 is a Dash 036 O-ring made from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 2.375 inches inside diameter, 2.5 inches outside diameter, and 0.0625 inches thick. NBR compound delivers reliable resistance to petroleum-based fluids, making this O-ring a standard choice for sealing applications in hydraulic systems, pneumatic assemblies, and fluid-handling plumbing components. With a hardness rating of 70 Shore A, the ring maintains its sealing profile under compression across a wide service temperature range. Licensed trades including plumbers, HVAC technicians, and fluid-system mechanics reach for Dash 036 NBR O-rings as replacement seals in valve bodies, fittings, and pump housings.

This O-ring suits residential and commercial sealing applications wherever a Dash 036 NBR compound ring is specified. Typical install scenarios include replacement of worn or cracked seals in ball valves, gate valves, union fittings, and hydraulic manifolds. The 70 Shore A hardness makes it appropriate for moderate-pressure fluid circuits using petroleum-based or water-based media. It is rated for service from -40 degrees F to 275 degrees F, covering most in-building HVAC, plumbing, and light industrial fluid-system conditions. This part is sold individually; minimum order quantity is 25 pieces.

Compatibility

Designed as a standard Dash 036 replacement O-ring for any groove or fitting machined to AS568 Dash 036 dimensions. Suitable for use with petroleum-based oils, hydraulic fluids, and water in HVAC, plumbing, and fluid-handling assemblies. Not FDA approved; not intended for food-contact or medical applications.

Installation Notes

O-ring installation should be performed by a qualified plumber, HVAC technician, or hydraulic system mechanic. Always depressurize and isolate the system before removing the old seal, and verify the groove dimensions match Dash 036 specifications before installation. Lightly lubricate the O-ring with a compatible fluid or assembly lubricant before seating to prevent twisting or tearing during installation. Do not roll or stretch the ring beyond its natural diameter during handling.
