Value Collection ZMSCA80210 Aflas O-ring Dash 210 80 Duro

Product Description

The Value Collection ZMSCA80210 is an Aflas O-ring rated for demanding sealing applications across a wide temperature range of 25 to 450 degrees F. This round cross-section ring measures 0.75 inches inside diameter, 1.0 inch outside diameter, and 0.125 inches thick, conforming to Dash 210 sizing. With an 80 durometer hardness rating, it delivers a firm, reliable seal in systems where compression set resistance is critical. Licensed HVAC technicians, plumbers, and refrigeration mechanics commonly specify Aflas elastomers where standard nitrile or EPDM compounds fall short. Sold in packs of 10.

Aflas is a fluoroelastomer compound chosen for applications involving refrigeration fluids including Freon-type refrigerants, hydraulic oils, fuels, brake fluids, acetic acid, animal oils, and bases. The ZMSCA80210 is well suited for residential and commercial HVAC refrigeration circuits, hydraulic systems, and chemical-handling assemblies where ozone, weather, and fluid compatibility are primary concerns. It is not FDA approved and should not be specified for food-contact applications.

Key Features

• Aflas fluoroelastomer construction for excellent refrigerant and chemical fluid compatibility
• Temperature range of 25 to 450 degrees F for use in both low-temperature and high-temperature systems
• 80 durometer hardness provides firm compression and good compression set resistance
• Dash 210 standard sizing for straightforward cross-reference and replacement
• Good ozone and weather resistance for installations in exposed or outdoor environments
• Moderate resistance to petroleum products suits hydraulic and fuel system service

Compatibility

Compatible with systems and media including acetic acid, animal oils, bases, brake fluids, fuels, hydraulic oil, and refrigeration fluids. Designed as an OEM-style Dash 210 replacement O-ring for use wherever Aflas elastomer and 80 durometer hardness are specified.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or hydraulic system mechanics. Always depressurize and isolate the system before removing or installing any O-ring seal. Inspect the seating groove for nicks, corrosion, or debris before installing the new ring, and avoid using sharp tools that could nick the elastomer. Follow applicable codes such as ASHRAE 15 for refrigeration systems or the Uniform Mechanical Code for HVAC and plumbing applications.
