Value Collection ZMSCH90107 O-ring Dash 107 Nitrile 90 Duro

Product Description

The VALUE COLLECTION ZMSCH90107 is a Dash 107 O-ring made from Nitrile Butadiene Rubber (Buna-N), the most widely used elastomer for sealing applications in trade and industrial settings. It measures 0.219 inches inner diameter, 0.406 inches outer diameter, and 0.094 inches thick, with a 90 durometer hardness rating classified as extra hard. The round cross-section profile delivers reliable compression set performance across a working temperature range of -40 degrees F to 250 degrees F. HVAC technicians, plumbers, and mechanical contractors reach for Buna-N O-rings when sealing joints, fittings, and valves exposed to petroleum-based fluids and refrigerants.

This O-ring is suited for use in hydraulic systems, pneumatic assemblies, fuel lines, refrigeration components, and plumbing fittings where petroleum product exposure is expected. Its extra-hard 90 durometer compound resists extrusion under pressure better than softer grades, making it a practical choice for high-cycle valve seats, pump seals, and fitting connections in both residential and light commercial mechanical systems. It ships in a package quantity of 100 units, making it appropriate for service shops maintaining seal inventory for routine maintenance work.

Key Features

• Buna-N (Nitrile Butadiene Rubber) construction offers excellent resistance to petroleum products including oils, fuels, and hydraulic fluids
• 90 durometer extra-hard rating resists extrusion and wear in high-pressure sealing applications
• Operating temperature range of -40 degrees F to 250 degrees F suits most HVAC, plumbing, and refrigeration environments
• Round cross-section Dash 107 profile conforms to SAE and MIL-Spec standards
• Tear and abrasion resistance extends service life in dynamic and static sealing applications
• Package quantity of 100 supports stocking for fleet service or shop inventory

Compatibility

Compatible with petroleum products, oils, fuels, and hydraulic fluids. Meets SAE and MIL-Spec standards. Not FDA approved. Should not be stored in direct sunlight or near motors or other electrical equipment that may generate ozone.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or pipefitters as part of valve, fitting, or pump seal service. Always shut off fluid supply and depressurize the system before replacing O-rings. Lightly lubricate the O-ring with a compatible fluid or assembly lubricant before seating to prevent tearing during installation. Do not overstretch the ring during placement, and inspect the mating groove for burrs or damage before assembly.
