Value Collection ZMSCH70FDA224 O-ring Dash 224 Nitrile Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA224 is a Dash 224 Nitrile Butadiene Rubber (Buna-N) O-ring with a round cross section, measuring 1.734 inches inside diameter, 2.000 inches outside diameter, and 0.125 inches thick. 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 quantity of 10. Buna-N is the most widely used O-ring elastomer in the trade and is the standard choice for sealing applications involving petroleum-based fluids. Licensed plumbers, pipefitters, HVAC technicians, and maintenance mechanics install this type of seal in hydraulic systems, fuel systems, and fluid-handling assemblies.

This O-ring is suited for residential and commercial applications where petroleum product resistance is required. Its working temperature range spans -40 degrees F to 250 degrees F, making it appropriate for a broad range of fluid sealing environments. The FDA-approved White Buna-N compound also makes it acceptable for use in food-processing and sanitary plumbing applications where material compliance is required. Typical installation scenarios include pump seals, valve bodies, fittings, and hydraulic cylinder assemblies.

Compatibility

Compatible with petroleum products and petroleum-based fluids. Designed as a standard Dash 224 O-ring replacement for any groove or fitting calling for the Dash 224 cross-section dimension in Buna-N or FDA-approved Buna-N compounds. Not recommended for use with ozone-generating equipment, in direct sunlight exposure, or in applications requiring compatibility with ozone, strong acids, or ketones.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians during pump, valve, or fitting service. Shut off and depressurize the system completely before removing the old O-ring or installing a replacement. Apply a compatible lubricant to ease installation and prevent tearing during seating. Avoid storing O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade Buna-N elastomer over time.
