Value Collection ZMSCH70FDA325 O-ring Dash 325 Buna-n Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA325 is a Dash 325 O-ring manufactured from white Buna-N (Nitrile Butadiene Rubber) with FDA approval, making it suitable for use in food-grade and fluid-handling applications. It measures 1.475 inches inside diameter, 1.875 inches outside diameter, and 0.1875 inches (3/16 inches) thick, with a round cross section. Rated at 70 Shore A hardness, this O-ring delivers strong compression set resistance, tear resistance, and abrasion resistance. Licensed plumbers, HVAC technicians, and equipment maintenance professionals install this type of seal in pumps, valves, fittings, and fluid system connections. It meets SAE and MIL-Spec standards.

This O-ring is designed for applications where contact with petroleum-based fluids is expected, including hydraulic systems, fuel systems, and general plumbing assemblies. Its FDA-approved white Buna-N compound also makes it appropriate for equipment used in food processing, beverage systems, and sanitary fluid handling. The Dash 325 designation follows the standard AS568 numbering system, allowing straightforward cross-referencing across suppliers and OEM documentation. This part is sold in a package quantity of 10.

Compatibility

Compatible with petroleum products and petroleum-based fluid systems. Suited for valves, pumps, fittings, and fluid connections requiring a Dash 325 O-ring with FDA-compliant Buna-N material. Should not be used in direct ozone exposure environments or near motors and electrical equipment that generate ozone.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Depressurize and isolate the fluid system fully before removing the existing O-ring or installing a replacement. Inspect the groove and mating surfaces for damage, debris, or corrosion before seating the new O-ring. Do not store Buna-N O-rings in direct sunlight or near ozone-generating equipment, as ozone degrades the elastomer.
