Value Collection ZMSCA80008 Aflas O-ring Dash 008

Product Description

The VALUE COLLECTION ZMSCA80008 is a Dash 008 Aflas O-ring designed for static and dynamic sealing applications across HVAC, refrigeration, plumbing, and industrial systems. With an inside diameter of 0.188 inches, an outside diameter of 0.313 inches, and a cross-section thickness of 0.0625 inches (1/16 inch), this round-profile O-ring seats precisely in standard Dash 008 grooves. The Aflas compound delivers an 80 Shore A durometer hardness, placing it in the hard hardness rating category. Its operating temperature range spans 25 degrees F to 450 degrees F, making it suitable for high-heat sealing environments where standard nitrile or EPDM compounds fall short.

This O-ring is used in applications involving refrigeration fluids including Freon-type refrigerants, hydraulic oil, brake fluids, fuels, acetic acid, animal oils, and bases. It is well suited for residential and commercial HVAC refrigerant circuits, hydraulic lines, fuel handling equipment, and chemical processing systems. The Aflas compound offers moderate resistance to petroleum products along with good ozone and weather resistance, making it a practical choice for outdoor or exposed installations. Plumbers, HVAC technicians, and industrial maintenance professionals commonly specify Aflas seals where fluorocarbon or nitrile compounds are not compatible with the service fluid.

Key Features

• Aflas compound with good compression set performance for long-term sealing reliability
• Operating range of 25 degrees F to 450 degrees F for high-temperature service
• 80 Shore A durometer (hard rating) for firm groove seating and extrusion resistance
• Excellent compatibility with refrigeration fluids, hydraulic oil, fuels, and chemical media
• Good ozone and weather resistance for outdoor or exposed service environments
• Standard Dash 008 sizing for straightforward groove-matched replacement

Compatibility

Designed as an OEM-style replacement O-ring for any application requiring a Dash 008 cross-section seal in Aflas compound. Compatible service media include acetic acid, animal oils, bases, brake fluids, fuels, hydraulic oil, and refrigeration fluids.

Installation Notes

O-ring installation should be performed by a qualified HVAC technician, plumber, or industrial mechanic depending on the application. Always relieve system pressure and isolate the circuit before removing the existing seal. Inspect the mating groove for nicks, burrs, or contamination before seating the new O-ring. Avoid twisting or pinching the O-ring during installation, and use only a lubricant compatible with Aflas compound and the system fluid.
