Value Collection ZMSCH70003 O-ring Dash 003 Nbr 100-pack

Product Description

The VALUE COLLECTION ZMSCH70003 is a Dash 003 Buna-N (Nitrile Butadiene Rubber) O-ring packaged in a 100-piece set. It measures 0.0625 inches inside diameter, 0.1880 inches outside diameter, and 0.0625 inches in cross-section thickness with a round cross-section profile. Rated at Shore A hardness 70, this O-ring is the most widely used elastomer type in hydraulic, pneumatic, and fluid-sealing applications. It is installed by licensed plumbers, HVAC technicians, and fluid-system mechanics where a reliable, petroleum-resistant seal is required.

This O-ring is suited for use in residential and commercial systems that involve petroleum-based fluids, oils, fuels, and hydraulic media. The Dash 003 sizing is a standard AS568 dimension commonly found in small-bore valve bodies, fittings, manifolds, and instrumentation ports. Its working temperature range of -40 degrees F to 250 degrees F makes it appropriate for a broad range of indoor and outdoor service environments.

Key Features

• Buna-N (NBR) elastomer provides excellent resistance to petroleum products, hydraulic oils, and fuels
• Round cross-section profile ensures consistent compression and sealing in standard O-ring grooves
• Shore A hardness of 70 balances flexibility with compression set resistance
• Operating temperature range: -40 degrees F to 250 degrees F
• Meets SAE and MIL-Spec standards
• Supplied in a 100-piece package, MOQ of 1 package

Compatibility

Designed as a standard Dash 003 O-ring replacement compatible with petroleum-based fluid systems, hydraulic circuits, and pneumatic assemblies that accept AS568 Dash 003 dimensioned seals. Compatible materials include petroleum products and petroleum-based hydraulic fluids. Not rated for ozone or UV-exposure environments.

Installation Notes

Power down or depressurize the system fully before replacing any O-ring seal. Lightly lubricate the O-ring with a compatible petroleum-based grease or the system fluid prior to installation to reduce the risk of tearing during assembly. Avoid storing these O-rings in direct sunlight or near motors, transformers, or other equipment that generates ozone, as ozone degrades NBR elastomers. Follow applicable system manufacturer torque specifications and relevant plumbing or mechanical codes for the assembly being serviced.
