Value Collection ZMSCH70037 Nbr O-ring Dash 037 100 Pack

Product Description

The VALUE COLLECTION ZMSCH70037 is a Dash 037 O-ring made from Nitrile Butadiene Rubber (NBR), also known as Buna-N, one of the most widely used elastomers in sealing applications across plumbing, hydraulic, and fluid-handling systems. This O-ring measures 2.5 inches inside diameter, 2.625 inches outside diameter, and 0.0625 inches thick, with a round cross section and a Shore hardness rating of 70. It is sold in a pack of 100. NBR offers excellent resistance to petroleum-based fluids along with strong compression set, tear resistance, and abrasion resistance, making it a reliable choice for high-cycle sealing environments.

This O-ring is suited for use in residential and commercial plumbing, HVAC equipment, hydraulic fittings, and general fluid-handling assemblies where contact with petroleum products is expected. The Dash 037 sizing is a standard AN/SAE designation, making this O-ring a common replacement or stocking item for service technicians maintaining pumps, valves, fittings, and manifolds. Its temperature range of -40 degrees F to 250 degrees F covers most mechanical service conditions encountered in the field. The 100-piece pack quantity supports shop stocking and bulk service work.

Key Features

• Buna-N (NBR) material with excellent petroleum-product resistance
• Standard Dash 037 sizing for broad cross-trade compatibility
• Round cross section for consistent seating and reliable static or dynamic sealing
• Rated for service temperatures from -40 degrees F to 250 degrees F
• Shore hardness of 70 for a balance of flexibility and compression set resistance
• Meets SAE and MIL-Spec standards

Compatibility

Designed for use with petroleum-based fluids and compatible fluid-handling systems calling for a Dash 037 standard O-ring in Buna-N material, per SAE and MIL-Spec standards.

Installation Notes

Installation is performed by plumbers, hydraulic technicians, HVAC technicians, and general mechanical trades. Always depressurize and isolate the system before removing or replacing O-rings. Lightly lubricating the O-ring with a compatible fluid or petroleum-based grease prior to installation reduces the risk of rolling or tearing during seating. Do not store O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as this degrades NBR material over time.
