Value Collection ZMSCH90117 O-ring Dash 117 Nbr 90 Duro 50pk

Product Description

The VALUE COLLECTION ZMSCH90117 is a Dash 117 Nitrile Butadiene Rubber (Buna-N) O-ring used for fluid and gas sealing in plumbing, HVAC, and mechanical systems. It measures 0.813 inches inside diameter, 1 inch outside diameter, and 0.094 inches thick with a round cross section. Rated at 90 durometer (extra hard), this O-ring provides firm compression set resistance and strong sealing performance under pressure. The Buna-N elastomer delivers excellent resistance to petroleum-based fluids, mineral oils, and common refrigeration oils. Operating range spans -40 degrees F to 250 degrees F. Licensed plumbers, HVAC techs, and mechanical service professionals install this type of O-ring during valve, fitting, pump, and compressor service.

This Dash 117 O-ring fits applications where a 0.813-inch ID seal is required, including plumbing shutoff valves, hydraulic fittings, refrigeration compressor ports, pump housings, and general mechanical assemblies that contact mineral oil or petroleum-based fluids. The 90-durometer hardness makes it well suited for higher-pressure connections where softer O-rings may extrude. Sold in a package of 50, this SKU is appropriate for service fleets, shop stock, or multi-unit repair jobs. Meets SAE and MIL-Spec standards. Not FDA approved, so it is not rated for direct food-contact applications.

Compatibility

Designed as an OEM-style replacement or service-stock O-ring for any application requiring a Dash 117 Buna-N seal. Compatible with mineral oil and petroleum-based fluid systems. Not recommended for use with ozone-generating equipment, strong acids, ketones, or direct sunlight storage environments.

Installation Notes

Install by licensed plumbers, HVAC technicians, or qualified mechanical technicians following applicable IPC or IFGC guidelines. Before replacing an O-ring, shut off the fluid or refrigerant supply and relieve system pressure completely. Lightly lubricate the O-ring with a compatible lubricant before seating to prevent tearing during installation. Do not store Buna-N O-rings near motors, ozone-generating equipment, or in direct sunlight, as ozone and UV exposure degrade nitrile rubber over time.
