Value Collection ZMSCH70FDA228 O-ring Dash 228 Buna-n Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA228 is a Dash 228 O-ring manufactured from Buna-N (Nitrile Butadiene Rubber) with FDA approval for use in food-contact and sanitary fluid systems. It measures 2.234 inches inside diameter, 2.5 inches outside diameter, and 0.125 inches thick with a round cross section. Hardness is rated at 70 Shore A, placing it in the hard rating category. This O-ring is sold in packages of 10 and is installed by plumbers, HVAC technicians, and mechanical service professionals in hydraulic, pneumatic, and fluid handling applications where petroleum-based media compatibility is required.

This O-ring is suited for residential and commercial sealing applications involving petroleum products, oils, fuels, and hydraulic fluids. The Buna-N elastomer delivers reliable compression set resistance and strong tear and abrasion resistance, making it a common choice for pump seals, valve stems, pipe fittings, and fluid connectors. It is rated for continuous service from -40 degrees F to 250 degrees F. The white color and FDA-approved compound make it appropriate for food processing equipment, beverage systems, and sanitary plumbing where incidental food contact is a concern.

Compatibility

Compatible with petroleum products and petroleum-based hydraulic fluids. Buna-N is the most widely used O-ring elastomer and fits standard Dash 228 grooves per SAE and MIL-Spec dimensional standards. Not recommended for exposure to ozone, direct sunlight during storage, or environments near motors and electrical equipment that generate ozone.

Installation Notes

O-rings in this size range are installed by licensed plumbers, HVAC technicians, and industrial mechanics. Always depressurize and de-energize the system before disassembling any fitting, valve, or pump housing. Lubricate the O-ring with a compatible fluid or O-ring lubricant to prevent twisting or nicking during installation. Do not store unused O-rings in direct sunlight or near ozone-generating equipment such as electric motors.
