Value Collection ZMSCH70124 O-ring Dash 124 Nbr 70A 100-pack

Product Description

The VALUE COLLECTION ZMSCH70124 is a Dash 124 Nitrile Butadiene Rubber (NBR) O-ring designed for static and dynamic sealing applications in fluid and pneumatic systems. It measures 1.25 inches inside diameter, 1.438 inches outside diameter, and 0.0937 inches thick with a round cross section. Rated at 70 Shore A hardness, this Buna-N elastomer provides excellent resistance to petroleum-based fluids, strong compression set recovery, and solid tear and abrasion resistance. Sold in a package of 100, it suits maintenance shops, service vans, and production environments that need reliable sealing stock on hand.

This O-ring is suited for plumbing, hydraulic, pneumatic, and general industrial sealing work where contact with petroleum products is expected. The Buna-N compound is the most widely used O-ring elastomer in trade service, making it a standard choice for pump seals, valve stems, fittings, and fluid connectors. It handles a working temperature range of -40 degrees F to 250 degrees F, covering most residential and light commercial application environments. Plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals routinely stock this size.

Key Features

• Buna-N (Nitrile Butadiene Rubber) compound — excellent resistance to petroleum-based fluids and lubricants
• 70 Shore A hardness rating — hard durometer suitable for a wide range of pressure sealing applications
• Temperature range: -40 degrees F to 250 degrees F working range
• Round cross section, Dash 124 standard sizing for drop-in replacement use
• Meets SAE and MIL-Spec standards
• Pack of 100 units — practical for shop stock, service kits, and production use

Compatibility

Designed for use with petroleum products and compatible fluids in standard Dash 124 O-ring grooves per SAE and MIL-Spec dimensional standards. Not rated for FDA-regulated food or pharmaceutical contact applications.

Installation Notes

De-energize and depressurize the system before removing any seals or fittings. Inspect the O-ring groove for burrs, corrosion, or damage before installing a new ring. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant to ease installation and reduce the risk of pinching or tearing. Do not store unused O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as ozone accelerates NBR degradation.
