Value Collection ZBD9984-16 O-ring Dash 138 Nbr 2.13 in Id

Product Description

The VALUE COLLECTION ZBD9984-16 is a Dash 138 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 2.13 inches inside diameter, 2.31 inches outside diameter, and 0.09 inches thick. With a Shore A hardness of 70 and a service temperature range of -40 degrees F to 275 degrees F, this O-ring is suited for sealing applications that require resistance to petroleum-based fluids, hydraulic oils, and fuels. It is commonly installed by plumbers, HVAC technicians, and industrial maintenance technicians wherever a reliable static or dynamic seal is needed in fluid-handling systems.

This O-ring is used in a wide range of sealing applications including hydraulic fittings, pneumatic assemblies, pump housings, valve stems, and plumbing connections. Its NBR compound performs well in systems that circulate oils, fuels, water, and many common refrigerants. The Dash 138 designation makes it straightforward to cross-reference against standard AS568 sizing charts when specifying replacements or servicing existing equipment.

Key Features

• Dash 138 standard sizing: 2.13 inches ID, 2.31 inches OD, 0.09 inches thick
• Nitrile Butadiene Rubber compound resists petroleum-based fluids, oils, and fuels
• Shore A hardness of 70 for firm, reliable sealing under compression
• Operating temperature range of -40 degrees F to 275 degrees F
• Round cross section for consistent compression in standard O-ring grooves

Compatibility

Designed as a standard AS568 Dash 138 replacement O-ring for hydraulic, pneumatic, plumbing, and fluid-handling assemblies that require an NBR seal at this dimensional specification.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance technicians. Depressurize and drain the system completely before removing the old O-ring. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before seating it to reduce the risk of tearing during assembly. Avoid overstretching the ring during installation and confirm the groove dimensions match the Dash 138 cross section before finalizing the repair.
