Value Collection ZMSCH70023 O-ring Dash 023 Nbr 70 Duro

Product Description

The VALUE COLLECTION ZMSCH70023 is a Dash 023 O-ring manufactured from Buna-N nitrile butadiene rubber (NBR), one of the most widely used elastomers in fluid sealing applications. The ring measures 1.0625 inches inside diameter, 1.1880 inches outside diameter, and 0.0625 inches thick, with a round cross section and a Shore A hardness of 70. This O-ring delivers excellent resistance to petroleum-based fluids, good compression set resistance, and strong tear and abrasion resistance. It is sold in a package quantity of 100 units, making it suitable for shop stock, service van replenishment, or production assembly use. Licensed plumbers, HVAC technicians, and industrial maintenance technicians are the typical installers.

This O-ring is suited for static and dynamic sealing applications in hydraulic systems, pneumatic fittings, fuel system components, refrigeration lines, and general plumbing connections where petroleum-based fluid compatibility is required. The NBR compound performs across a temperature range of -40 degrees F to 250 degrees F, making it appropriate for both low-ambient outdoor installs and higher-temperature mechanical environments. It meets SAE and MIL-Spec standards and is commonly stocked for use in residential and commercial HVAC, plumbing, and industrial maintenance operations.

Key Features

• 70 Shore A hardness rating for firm sealing under compression
• Round cross section per Dash 023 sizing standard
• Operating temperature range: -40 degrees F to 250 degrees F
• Meets SAE and MIL-Spec standards
• Package quantity of 100 units for bench stock or fleet use

Compatibility

Compatible with petroleum products and petroleum-based fluids. Designed as a standard Dash 023 O-ring replacement for hydraulic, pneumatic, fuel, and plumbing seal applications that specify Buna-N (NBR) elastomer. Not recommended for use with ozone, sunlight exposure, or equipment generating ozone such as electric motors.

Installation Notes

O-rings should be installed by a qualified technician following applicable plumbing, HVAC, or mechanical codes. Depressurize and drain the system before replacing any seal. Lubricate the O-ring lightly with a compatible lubricant prior to installation to prevent tearing during assembly. Do not store unused O-rings in direct sunlight or near motors or other electrical equipment that may generate ozone, as this degrades the NBR compound over time.
