Value Collection ZMSCH70001 O-ring Dash 001 Nbr 100-pack

Product Description

The VALUE COLLECTION ZMSCH70001 is a Dash 001 Buna-N (Nitrile Butadiene Rubber) O-ring designed for use in fluid and pneumatic sealing applications across HVAC, plumbing, and general mechanical systems. With a 0.0312-inch inside diameter, a 0.0940-inch outside diameter, and a 1/32-inch round cross section, this is one of the smallest standard dash-numbered O-rings in common trade use. The compound carries a Shore A hardness of 70 and is rated for continuous service from -40 degrees F to 250 degrees F. Buna-N is the most widely used O-ring elastomer in the industry, valued for its reliable compression set and resistance to petroleum-based fluids. Sold in a 100-piece package.

This O-ring is suited for sealing applications involving petroleum products, hydraulic oils, fuels, and mineral-based lubricants in residential and light commercial systems. Typical installation scenarios include valve bodies, fittings, manifolds, and small-bore pneumatic or hydraulic components where a Dash 001 SAE or MIL-Spec standard O-ring is specified. HVAC technicians, plumbers, and mechanical contractors commonly stock this size for field repairs on metering devices, solenoid valves, and similar compact assemblies. The black color aids visual inspection after installation.

Key Features

• Buna-N (NBR) elastomer — the most widely used O-ring material for petroleum-fluid compatibility
• Rated -40 degrees F to 250 degrees F continuous working temperature range
• Round cross section with Shore A 70 hardness for reliable compression set
• Meets SAE and MIL-Spec standards for Dash 001 O-rings
• Excellent tear and abrasion resistance for long service life in dynamic or static seals
• Sold in a 100-piece package with a minimum order quantity of 1 package

Compatibility

Designed as a standard Dash 001 O-ring replacement compatible with petroleum products and petroleum-based fluid systems. Not recommended for use with ozone-generating equipment, direct sunlight exposure, or non-petroleum fluid chemistries without confirming NBR compatibility. Not FDA approved.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or qualified mechanical service professionals. Always depressurize and isolate the system before replacing any O-ring seal. Lightly lubricate the O-ring with a compatible petroleum-based or system-appropriate lubricant before seating to reduce the risk of twisting or tearing during assembly. Do not store unused O-rings in direct sunlight or near motors or electrical equipment that may generate ozone, as this will degrade the NBR compound over time.
