Value Collection ZMSCH70FDA126 O-ring Dash 126 Nbr Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA126 is a Dash 126 nitrile butadiene rubber (NBR) O-ring rated for a wide range of fluid sealing applications in HVAC, plumbing, and fluid-handling systems. It features a 1.362-inch inside diameter, a 1.563-inch outside diameter, and a 0.0937-inch (3/32 inch) round cross section. The compound carries a Shore A hardness of 70 and meets FDA approval for use in food-contact environments. This O-ring is white in color and is sold in a package quantity of 25, making it a practical stocking item for service trucks and shop inventory. Licensed plumbers, HVAC technicians, and industrial mechanics are the primary installers.

This O-ring is suited for residential and commercial applications where petroleum-based fluid resistance is required. The NBR elastomer delivers excellent compression set resistance along with strong tear and abrasion resistance, making it a reliable choice for pump seals, valve stems, fittings, and fluid connectors. Its FDA-approved white compound also makes it appropriate for potable water and food-processing equipment where incidental contact is a concern. It conforms to SAE and MIL-Spec standards.

Compatibility

Compatible with petroleum products and petroleum-based fluids. Designed as a standard Dash 126 O-ring for use in grooves and fittings sized to AS568 Dash 126 specifications. Note: NBR should not be stored in direct sunlight or near motors or other electrical equipment that may generate ozone.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial mechanics. Shut off and depressurize the system fully before removing the old O-ring and seating the replacement. Lubricate the O-ring with a compatible fluid or grease prior to installation to prevent tearing during assembly. Inspect the seating groove for damage or debris before installing.
