Value Collection ZMSCA80011 Aflas O-ring Dash 011

Product Description

The VALUE COLLECTION ZMSCA80011 is a Dash 011 Aflas O-ring designed for static and dynamic sealing applications across HVAC, refrigeration, hydraulic, and chemical handling systems. Manufactured from Aflas (a fluoroelastomer-class material), this O-ring measures 0.313 inches inside diameter, 0.438 inches outside diameter, and 0.0625 inches thick with a round cross section. It carries a Shore A hardness rating of 80, placing it in the hard durometer range. The temperature range spans 25 degrees F to 450 degrees F, making it suitable for both low-temperature refrigeration service and high-temperature fluid sealing. Licensed HVAC technicians, plumbers, and hydraulic system technicians are the primary installers of this component.

This O-ring is suited for residential and commercial applications where chemical resistance to fuels, hydraulic oils, brake fluids, acetic acid, animal oils, and bases is required. It is particularly well-regarded for sealing refrigeration fluids including fluorinated refrigerants. The Aflas compound provides good ozone and weather resistance along with good compression set performance, making it a dependable choice in environments where standard nitrile or EPDM compounds would degrade. Sold in a package quantity of 25 units.

Key Features

• Aflas material with moderate resistance to petroleum products and excellent resistance to refrigeration fluids including fluorinated refrigerants
• Operating temperature range of 25 degrees F to 450 degrees F
• Shore A hardness of 80 (hard durometer rating)
• Good ozone and weather resistance for outdoor or exposed installations
• Good compression set for reliable long-term sealing under load
• Round cross-section profile conforming to Dash 011 standard sizing

Compatibility

Compatible with systems handling acetic acid, animal oils, bases, brake fluids, fuels, hydraulic oil, and refrigeration fluids such as fluorinated refrigerants. Designed as an OEM-style replacement or service O-ring for any application requiring a Dash 011 standard size in Aflas compound.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or hydraulic system mechanics depending on the application. Always depressurize and isolate the system before removing or replacing O-rings to prevent fluid release or injury. Inspect the groove and mating surfaces for nicks or corrosion before seating the new O-ring. Aflas compounds are compatible with a limited range of lubricants — confirm lubricant compatibility with the fluid being sealed before applying any O-ring assembly lubricant.
