Value Collection ZMSCH90022 O-ring Dash 022 Buna-n Pack of 100

Product Description

The VALUE COLLECTION ZMSCH90022 is a Dash 022 Buna-N (Nitrile Butadiene Rubber) O-ring designed for sealing applications in fluid and pneumatic systems. It measures 1 inch inside diameter, 1.125 inches outside diameter, and 0.0625 inches thick with a round cross section. Rated at 90 durometer (extra hard), this O-ring is well suited for high-compression sealing environments. The operating temperature range spans -40 degrees F to 250 degrees F. Installation is performed by HVAC technicians, plumbers, and industrial maintenance professionals wherever a reliable elastomeric seal is required in petroleum-based fluid service.

This O-ring is used in residential and commercial applications wherever a Dash 022 standard-size seal is specified. Common install scenarios include hydraulic fittings, refrigerant service valves, pump connections, and plumbing unions that handle petroleum products or mineral-oil-based fluids. The Buna-N compound offers excellent resistance to petroleum products, making it a standard choice for fuel, oil, and hydraulic service points. Each purchase unit contains 100 O-rings, suited for shop stock, service van inventory, or production line use. Minimum order quantity is 1 package of 100 pieces.

Key Features

• Buna-N (Nitrile Butadiene Rubber) compound — the most widely used O-ring elastomer for petroleum service
• 90 durometer extra-hard rating provides excellent compression set resistance
• Operating range of -40 degrees F to 250 degrees F suits broad temperature environments
• Excellent tear and abrasion resistance for long service life at dynamic sealing points
• Meets SAE and MIL-Spec standards
• Packed in quantities of 100 for shop stock or fleet service inventory

Compatibility

Compatible with petroleum products, mineral-oil-based hydraulic fluids, and similar media. Suitable for use wherever a Dash 022 O-ring specification is called out. Not recommended for ozone-rich environments, direct sunlight storage, or proximity to motors and other equipment that generate ozone.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, and industrial mechanics during routine maintenance or component replacement. Always depressurize and isolate the system before removing or installing O-rings. Lightly lubricate the O-ring with a compatible fluid prior to seating to prevent tearing during assembly. Inspect the groove and mating surfaces for nicks or corrosion before installation to ensure a proper seal.
