Value Collection ZMSCH90910 O-ring Dash 910 Nbr 90 Duro

Product Description

The VALUE COLLECTION ZMSCH90910 is a Dash 910 O-ring made from Nitrile Butadiene Rubber (Buna-N), one of the most widely used elastomers in fluid sealing applications. It measures 0.755 inches inner diameter, 0.949 inches outer diameter, and 0.097 inches cross-section thickness. The compound is rated at 90 durometer, placing it in the extra-hard hardness range. It carries a working temperature range of -40 to 250 degrees F, making it suitable for demanding mechanical and hydraulic environments. Each purchase covers a package of 100 rings. Installed by plumbers, HVAC technicians, and industrial mechanics wherever petroleum-based fluid sealing is required.

This O-ring is used in hydraulic cylinders, pneumatic fittings, pump housings, refrigerant valves, and general plumbing assemblies where petroleum-based fluids are present. The Buna-N compound delivers excellent resistance to petroleum products, fuels, and oils. Its extra-hard 90 durometer rating helps it maintain shape under pressure and resist extrusion in high-load sealing grooves. The round cross-section profile fits standard Dash 910 gland dimensions. Typical applications include residential and commercial HVAC equipment, plumbing shutoff valves, and hydraulic system components across trade and industrial settings.

Key Features

• Buna-N (Nitrile Butadiene Rubber) compound offers excellent resistance to petroleum products, fuels, and oils
• 90 durometer extra-hard rating resists extrusion and compression set under high-load conditions
• Operating range of -40 to 250 degrees F suits a wide range of mechanical and HVAC applications
• Dash 910 standard sizing fits corresponding gland and groove dimensions without modification
• Round cross-section profile ensures consistent sealing contact
• Meets SAE and MIL-Spec standards

Compatibility

Compatible with petroleum products and systems that use Dash 910 O-ring gland dimensions per SAE and MIL-Spec standards. Not recommended for use with ozone-generating equipment or in direct sunlight exposure during storage. Not FDA approved.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or hydraulic system mechanics depending on the application. De-pressurize and isolate the system before removing any fittings or components. Inspect the gland and groove for damage or contamination before seating the new ring. Avoid storing Buna-N O-rings near motors, electrical equipment, or in direct sunlight, as ozone exposure degrades the elastomer.
