Value Collection ZMSCH70FDA018 O-ring Dash 018 Buna-n Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA018 is a Dash 018 O-ring manufactured from Buna-N (Nitrile Butadiene Rubber), the most widely used elastomer in sealing applications. It measures 0.739 inches inside diameter, 0.875 inches outside diameter, and 0.0625 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring carries FDA approval and meets SAE and MIL-Spec standards. It is sold in a package of 25. HVAC technicians, plumbers, and equipment service pros use this O-ring wherever a reliable static or dynamic seal is required in petroleum-compatible fluid systems.

This O-ring is suited for residential and commercial applications involving petroleum-based fluids, hydraulic oils, fuels, and many lubricants. The Dash 018 size is a common fit in fittings, valve stems, pump housings, refrigeration service ports, and general plumbing connections. Its FDA-approved material makes it appropriate for equipment that contacts food-grade oils or similar regulated fluids. The working temperature range of -40 degrees F to 250 degrees F covers the majority of HVAC, plumbing, and light industrial service conditions.

Compatibility

Compatible with petroleum products, hydraulic oils, fuels, and lubricants. Not recommended for exposure to ozone, direct sunlight during storage, or equipment generating ozone such as motors and certain electrical components. Designed as a standard Dash 018 replacement O-ring for use in valves, fittings, pump seals, and similar assemblies requiring a 0.739 inches ID round-section seal.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or qualified maintenance personnel. Always depressurize and isolate the system before removing or replacing O-rings. Lightly lubricate the O-ring with a compatible fluid or grease before seating to avoid rolling or cutting during assembly. Do not store unused O-rings in direct sunlight or near motors and other ozone-generating electrical equipment, as ozone degrades nitrile rubber.
