Value Collection ZMSCH70FDA020 O-ring Dash 020 Nbr Pack of 25

Product Description

The VALUE COLLECTION ZMSCH70FDA020 is a Dash 020 nitrile butadiene rubber (NBR) O-ring with a 0.864 inch inside diameter, a 1.000 inch outside diameter, and a 0.0625 inch (1/16 inch) round cross section. Rated at 70 Shore A hardness, this white FDA-approved BUNA O-ring meets SAE and MIL-Spec standards. It is sold in a package of 25 and weighs 0.221 pounds per package. Licensed trades and maintenance professionals use it wherever a reliable petroleum-resistant seal is required in fluid and gas system connections.

This O-ring is suited for residential and commercial plumbing, HVAC refrigerant circuits, hydraulic assemblies, and general fluid-handling applications. Its NBR compound delivers excellent resistance to petroleum-based fluids including oils, fuels, and hydraulic fluids. The FDA-approved white compound also makes it appropriate for food-grade or potable-water-adjacent applications where compliance documentation is required. It should not be stored in direct sunlight or near motors and other equipment that may generate ozone, as ozone exposure degrades NBR elastomers over time.

Compatibility

Designed as a standard Dash 020 O-ring replacement compatible with petroleum-based fluid systems including hydraulic lines, plumbing fittings, HVAC service ports, and general mechanical assemblies requiring an NBR elastomer seal.

Installation Notes

O-ring installation is performed by plumbers, HVAC technicians, and hydraulic system mechanics during routine maintenance or component replacement. Always depressurize and isolate the system before removing or installing seals. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before seating to prevent rolling and tearing during assembly. Avoid using petroleum-incompatible greases or solvents that can swell or degrade NBR compounds.
