Value Collection ZBD9984-14 O-ring Nbr Dash 136 2in Id

Product Description

The VALUE COLLECTION ZBD9984-14 is a Dash 136 nitrile butadiene rubber (NBR) O-ring used to create static or dynamic fluid seals in plumbing, HVAC, and hydraulic assemblies. It measures 2 inches inside diameter with a 2.19-inch outside diameter and a 0.0937-inch (3/32 inch) round cross section. The NBR compound carries a Shore A hardness rating of 70, placing it in the hard category, and is rated for service from -40 degrees F to 275 degrees F. Plumbers, HVAC technicians, and industrial maintenance personnel install this O-ring wherever a reliable, fuel- and oil-resistant face or radial seal is required.

This O-ring is suited for residential and light commercial applications involving water, oils, fuels, and many hydraulic fluids. Common install scenarios include valve stems, pipe unions, pump housings, and fittings where the groove is sized for a standard Dash 136 cross section. The wide temperature range makes it a practical choice for both chilled-water and moderate-temperature hot-water systems, as well as fuel-handling assemblies in HVAC equipment.

Key Features

• Dash 136 standard sizing: 2 inches ID x 2.19 inches OD x 0.0937 inches thick
• Nitrile butadiene rubber (NBR) compound resists petroleum-based oils, fuels, and hydraulic fluids
• Shore A hardness of 70 provides a firm, reliable seal under compression
• Operating temperature range of -40 degrees F to 275 degrees F suits both refrigeration and hot-water service
• Round cross section ensures consistent seating in standard Dash 136 grooves

Compatibility

Designed as a standard replacement O-ring for any valve, fitting, pump, or housing that accepts a Dash 136 groove profile with a 2-inch inside diameter and 3/32-inch cross section thickness.

Installation Notes

Licensed plumbers and HVAC technicians should shut off system pressure and drain or isolate the affected line before replacing an O-ring seal. Lightly lubricate the O-ring with a compatible grease before seating it in the groove to prevent twisting or damage during assembly. Avoid using petroleum-based lubricants with non-NBR materials; confirm fluid compatibility before installation. Inspect the mating groove and seating surface for nicks or scoring that could compromise the seal.
