Value Collection ZMSCH90222 O-ring Dash 222 Nbr 90 Duro

Product Description

The VALUE COLLECTION ZMSCH90222 is a Dash 222 Nitrile Butadiene Rubber (NBR) O-ring with a 1.5-inch inside diameter, 1.75-inch outside diameter, and a 0.125-inch cross-section thickness. Rated at 90 durometer (extra hard), it delivers firm compression set resistance and strong sealing performance under pressure. The NBR compound provides excellent resistance to petroleum-based fluids, making it a dependable sealing element in hydraulic, pneumatic, and fluid-handling assemblies. Licensed plumbers, hydraulic technicians, and industrial maintenance mechanics install this O-ring as an OEM-style or aftermarket replacement in systems where petroleum-fluid exposure is a daily reality.

This O-ring is suited for residential and commercial applications involving petroleum products, oils, fuels, and hydraulic fluids. Its temperature range of -40 to 250 degrees F covers a wide span of operating conditions, from cold-climate equipment startups to high-temperature hydraulic circuits. Typical install scenarios include pump seals, valve stems, pipe unions, and cylinder end caps where a firm, round-cross-section elastomeric seal is required. The package quantity is 50 units, making it practical for service shops or contractors managing recurring seal replacements.

• Operating temperature range: -40 to 250 degrees F
• Excellent resistance to petroleum products, oils, and hydraulic fluids
• Round cross-section profile for consistent, predictable groove seating
• Meets SAE and MIL-Spec standards

Compatibility

Compatible with petroleum-based products and hydraulic fluids per supplier specifications. Designed as an OEM-style replacement or service O-ring for hydraulic, pneumatic, and fluid-handling assemblies requiring a Dash 222 NBR seal. Not FDA approved; not intended for food-contact or medical-grade applications.

Installation Notes

Installation should be performed by a qualified plumber, hydraulic technician, or industrial mechanic following applicable system service procedures. Depressurize and isolate the circuit before removing the old O-ring to prevent fluid release or injury. Lubricate the O-ring with a compatible petroleum-based or system-appropriate lubricant before seating it in the groove to reduce the risk of nicks or cuts during assembly. Do not store NBR O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as ozone exposure degrades the elastomer.
