The VALUE COLLECTION ZMSCH70102 is a Dash 102 Nitrile Butadiene Rubber (NBR/Buna-N) O-ring sold in a pack of 100. It features a round cross section with a 0.063 inch inside diameter, 0.250 inch outside diameter, and 0.0937 inch thickness. Rated at 70 Shore A hardness, this O-ring is designed for static and dynamic sealing applications where resistance to petroleum-based fluids is required. It is compatible with a working temperature range of -40 degrees F to 250 degrees F. HVAC technicians, plumbers, and fluid system mechanics commonly use this O-ring as a sealing element in valves, fittings, pumps, and hydraulic or pneumatic assemblies.
This O-ring is suited for residential and commercial applications involving petroleum-based lubricants, fuels, hydraulic oils, and similar fluids. Typical installation scenarios include valve stem seals, pipe fitting connections, pump housings, and refrigerant or fluid circuit service where a Dash 102 size is specified. The pack quantity of 100 makes it appropriate for service technicians stocking a van or shop inventory. It meets SAE and MIL-Spec standards, confirming dimensional and material consistency across the lot.
Compatible with petroleum products, hydraulic oils, and similar fluid media. Designed as a standard Dash 102 NBR O-ring replacement for valves, fittings, pumps, and sealing assemblies that specify a 0.063 inch ID by 0.250 inch OD by 0.0937 inch thick round cross section seal. Not recommended for use with ozone, strong acids, ketones, esters, or applications requiring FDA-compliant materials.
Installation should be performed by a qualified technician. Depressurize and de-energize the system before disassembling any fitting, valve, or pump housing to replace the O-ring. Lightly lubricate the O-ring with a compatible fluid prior to seating to prevent tearing during assembly. Avoid storing unused O-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as ozone exposure degrades NBR elastomer over time.
