Value Collection ZMSCH70FDA137 O-ring Dash 137 Nbr 10-pack

Product Description

The VALUE COLLECTION ZMSCH70FDA137 is a Dash 137 O-ring made from white Nitrile Butadiene Rubber (NBR/Buna-N) with a round cross section. It measures 2-1/16 inches inside diameter, 2-1/4 inches outside diameter, and 3/32 inches thick. Rated at Shore A 70 hardness, this O-ring carries FDA approval and meets SAE and MIL-Spec standards. It is sold in a package of 10 and is suited for plumbing, hydraulic, pneumatic, and fluid-handling applications where petroleum-based media resistance is required. Licensed plumbers, pipefitters, and hydraulic technicians are the primary installers.

This O-ring is designed for use in systems handling petroleum products, oils, fuels, and hydraulic fluids. The NBR compound provides excellent compression set resistance and strong tear and abrasion resistance across a working temperature range of -40 degrees F to 250 degrees F. FDA approval makes it appropriate for use in applications requiring food-grade sealing compliance. It is a widely used general-purpose elastomer appropriate for both residential and commercial fluid-system service.

Key Features

• FDA approved white NBR compound suitable for food-grade and petroleum-fluid applications
• Shore A 70 hardness rating provides firm, reliable sealing under compression
• Meets SAE and MIL-Spec standards for quality and dimensional consistency
• Operating range of -40 degrees F to 250 degrees F for broad service compatibility
• Round cross section ensures consistent gland seating and even load distribution
• Package of 10 units per order for stocking and service-call efficiency

Compatibility

Compatible with petroleum products, oils, fuels, and hydraulic fluids. Designed as an OEM-style replacement or maintenance O-ring for plumbing, hydraulic, and pneumatic systems requiring a Dash 137 NBR seal. Should not be used in direct sunlight exposure or near ozone-generating equipment such as electric motors.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or hydraulic technicians. Always depressurize and isolate the fluid circuit before removing the old O-ring and installing the replacement. Inspect the gland groove for scoring or debris before seating the new ring. Avoid stretching the O-ring excessively during installation to prevent premature failure.
