Value Collection ZMSCH70141 O-ring Dash 141 Nitrile Nbr

Product Description

The VALUE COLLECTION ZMSCH70141 is a Dash 141 Buna-N (Nitrile Butadiene Rubber) O-ring with a round cross section, designed for static and dynamic sealing applications across plumbing, hydraulic, pneumatic, and fluid-handling systems. It measures 2.313 inches inside diameter, 2.500 inches outside diameter, and 0.094 inches thick. Rated at 70 Shore A hardness, it delivers firm compression set resistance along with strong tear and abrasion resistance. Licensed HVAC technicians, plumbers, and mechanical contractors install this O-ring as a sealing element in fittings, valves, pumps, and couplings where petroleum-based fluid contact is expected.

This O-ring is suited for residential and commercial applications involving petroleum products, hydraulic fluids, and similar media. It performs reliably across a temperature range of -40 degrees F to 250 degrees F, making it appropriate for a wide range of service environments. Buna-N is the most widely used O-ring elastomer in trade applications due to its broad chemical compatibility and availability in standard dash sizes. This Dash 141 size fits standardized grooves per SAE and MIL-Spec dimensional standards.

Compatibility

Designed for use with petroleum products and compatible fluids in standard Dash 141 O-ring groove applications per SAE and MIL-Spec dimensional standards. Not FDA approved for food-contact or potable water service.

Installation Notes

O-rings of this type are installed by plumbers, HVAC technicians, and industrial mechanics as part of valve, fitting, pump, or coupling assemblies. Shut off fluid supply and relieve system pressure before replacing any O-ring in a pressurized system. Lightly lubricate the O-ring with a compatible fluid or grease prior to installation to prevent pinching or tearing during assembly. Do not store Buna-N O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as ozone exposure degrades the elastomer.
