Value Collection ZMSCH70FDA009 O-ring Dash 009 Nbr 25-pack

Product Description

The VALUE COLLECTION ZMSCH70FDA009 is a Dash 009 O-ring manufactured from white, FDA-approved Nitrile Butadiene Rubber (NBR/Buna-N) with a round cross section. It measures 0.219 inches inside diameter, 0.343 inches outside diameter, and 0.0625 inches thick. Rated at 70 Shore A hardness, it handles working temperatures from -40 degrees F to 250 degrees F and is compatible with petroleum-based fluids. This O-ring meets SAE and MIL-Spec standards. Sold in a package of 25, it is used by plumbing, HVAC, and mechanical service technicians for sealing applications requiring FDA compliance and strong resistance to petroleum products.

This O-ring is suited for residential and commercial applications where a small-diameter, petroleum-resistant seal is required. Its FDA-approved white NBR compound makes it appropriate for use in food-grade and potable-water-adjacent systems in addition to standard HVAC and plumbing service applications. The 70 Shore A hardness rating provides a balance of compression set resistance and sealing integrity in static and low-dynamic installations.

Installation Notes

O-rings of this type are installed by licensed plumbers, HVAC technicians, and mechanical service professionals. Always depressurize and isolate the system before replacing any seal. Lubricate the O-ring with a compatible, system-approved lubricant prior to seating to reduce the risk of tearing during installation. Do not store unused O-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as this degrades NBR elastomer.
