Value Collection ZMSCH70FDA232 O-ring Dash 232 Buna-n Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA232 is a Dash 232 O-ring manufactured from Buna-N (Nitrile Butadiene Rubber), the most widely used elastomer in industrial and fluid-handling applications. It measures 2.734 inches inside diameter, 3 inches outside diameter, and 0.125 inches thick, with a round cross section and a Shore A hardness rating of 70. This O-ring carries FDA approval and meets SAE and MIL-Spec standards, making it suitable for applications where food-grade or government-spec compliance is required. Plumbers, maintenance technicians, and industrial service professionals install this type of seal in pumps, valves, fittings, and fluid-system assemblies.

This O-ring is suited for sealing applications in residential, commercial, and light industrial environments where petroleum-based fluids, hydraulic oils, or fuels are present. Its rated operating temperature range of -40 degrees F to 250 degrees F covers most HVAC, plumbing, and mechanical equipment service conditions. The white color and FDA-approval status also make it appropriate for food-processing equipment, beverage systems, and potable water applications where material compliance is a specification requirement. Sold in a package of 10 units.

Key Features

• FDA approved Buna-N material suitable for food-grade and potable water applications
• Meets SAE and MIL-Spec standards for broad specification compliance
• Operating temperature range: -40 degrees F to 250 degrees F
• Excellent resistance to petroleum products, hydraulic fluids, and oils
• Strong compression set, tear resistance, and abrasion resistance
• Round cross section, Shore A hardness 70 for reliable static and dynamic sealing

Compatibility

Compatible with petroleum products and petroleum-based fluids per manufacturer data. Note: Buna-N is not recommended for exposure to ozone, direct sunlight, or near motors and electrical equipment that may generate ozone. Verify chemical compatibility with the specific fluid or media before installation.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics. Isolate and depressurize the system and shut off all fluid supply before removing or replacing seals. Inspect the groove dimensions and surface finish before installing the new O-ring to ensure proper fit and prevent premature failure. Avoid using sharp tools that could nick or cut the O-ring during installation; a light coating of compatible lubricant aids seating without compromising the seal.
