Value Collection ZMSCA80150 O-ring Aflas Dash 150

Product Description

The VALUE COLLECTION ZMSCA80150 is an Aflas o-ring with a 2.875-inch inside diameter, a 3.063-inch outside diameter, and a cross-section thickness of 0.094 inches. Aflas, a copolymer of tetrafluoroethylene and propylene, offers resistance to a wide range of aggressive media including fuels, hydraulic oils, brake fluids, bases, and refrigeration fluids. The compound is rated at 80 Shore A hardness, placing it in the hard durometer range. Operating temperature spans 25 degrees F to 450 degrees F. This o-ring is installed by HVAC technicians, plumbers, hydraulic system mechanics, and industrial maintenance professionals wherever a static or dynamic face or radial seal is required in chemically demanding service.

This o-ring suits residential and commercial applications where standard nitrile or EPDM compounds are inadequate due to chemical or thermal exposure. Common use cases include refrigeration systems handling Freon-type refrigerants, hydraulic circuits exposed to petroleum-based or synthetic fluids, brake system lines, and plumbing or process piping exposed to acetic acid, animal oils, or aggressive base solutions. The round cross-section and Dash 150 sizing conform to AS568 standard dimensions, making this a straightforward drop-in replacement in any groove machined to that standard.

Key Features

• Aflas compound provides moderate petroleum product resistance with excellent ozone and weather resistance
• Rated for refrigeration fluid sealing including Freon-type refrigerants
• 80 Shore A hardness for firm compression set performance in high-pressure or dynamic sealing environments
• Wide temperature range from 25 degrees F to 450 degrees F suits both low-ambient and high-heat installations
• Compatible with acetic acid, animal oils, bases, brake fluids, fuels, and hydraulic oil
• AS568 Dash 150 standard sizing for direct fitment in machined o-ring grooves

Compatibility

Designed for any application requiring an AS568 Dash 150 o-ring groove with an inside diameter of 2.875 inches and a cross-section of 0.094 inches. Consult equipment service documentation to confirm groove dimensions and chemical compatibility before installation.

Installation Notes

Shut down and depressurize the system fully before removing the old o-ring. Clean the groove and mating surfaces to remove debris, old lubricant, and any remnants of the previous seal. Apply a compatible lubricant to the o-ring before seating it to prevent twisting or tearing during assembly. Verify groove dimensions against AS568 Dash 150 specifications before installation, and follow applicable ASHRAE, NEC, or equipment manufacturer guidelines for the specific system being serviced.
