Value Collection ZMSCH70122 O-ring Dash 122 Nbr Pack of 100

Product Description

The VALUE COLLECTION ZMSCH70122 is a Dash 122 O-ring made from Nitrile Butadiene Rubber (Buna-N), one of the most widely used elastomers in fluid sealing applications. It measures 1.125 inches inside diameter, 1.313 inches outside diameter, and 0.0937 inches thick with a round cross section. The Buna-N compound provides excellent resistance to petroleum-based fluids, along with strong compression set recovery and solid tear and abrasion resistance. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this O-ring wherever a reliable, low-cost seal is needed in petroleum-compatible systems.

This O-ring is suited for use in hydraulic systems, pneumatic assemblies, fluid fittings, pumps, and valves that contact petroleum-based oils, fuels, and lubricants. With a working temperature range of -40 degrees F to 250 degrees F, it performs across a wide range of residential and light commercial service conditions. The package contains 100 pieces, making it practical for service shops and contractors who install or rebuild multiple assemblies at a time. Store away from direct sunlight and electrical equipment that may generate ozone to preserve elastomer integrity.

Compatibility

Compatible with petroleum-based products including oils, fuels, and lubricants. Designed as an OEM-style replacement or service O-ring for hydraulic fittings, pumps, valves, and fluid-handling assemblies that accept Dash 122 standard sizing.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanic familiar with fluid sealing procedures. Always depressurize and drain the system before removing or replacing O-rings. Lubricate the O-ring with a compatible fluid before installation to prevent tearing during assembly. Do not store Buna-N O-rings near motors, ozone-generating equipment, or in direct sunlight, as ozone and UV exposure degrade the elastomer over time.
