Value Collection ZMSCH70FDA024 O-ring Dash 024 Nbr Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA024 is a Dash 024 O-ring manufactured from white Nitrile Butadiene Rubber (NBR), also known as Buna-N. It features a round cross section with a 1.114-inch inside diameter, a 1.25-inch outside diameter, and a wall thickness of 0.0625 inches. With a Shore A hardness rating of 70, this O-ring delivers firm sealing performance suitable for static and dynamic applications. It carries FDA approval and meets SAE and MIL-Spec standards, making it appropriate for use in food-contact and regulated environments. Sold in a package of 10 units. Licensed plumbers, HVAC technicians, and mechanical tradespeople commonly specify this size for fluid and gas sealing duties.

This O-ring is suited for residential and commercial plumbing, HVAC, and hydraulic applications where petroleum-based fluids or gases are present. Its NBR compound provides excellent resistance to petroleum products, oils, and fuels. The Dash 024 sizing is a standard AN face seal and port plug dimension found across a wide range of fittings, valves, and fluid-system components. The FDA-approved white Buna-N compound also supports light food-processing and potable-water-adjacent applications where material compliance is required.

Not recommended for exposure to ozone, direct sunlight during storage, or proximity to motors and other ozone-generating electrical equipment.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical tradesperson. Shut off all fluid or gas supply and relieve system pressure before removing or installing O-rings. Lightly lubricate the O-ring with a compatible fluid or grease prior to seating to prevent tearing during assembly. Avoid using sharp tools that may nick or cut the cross section during installation.
