Value Collection ZMSCA80038 Aflas O-ring Dash 038

Product Description

The VALUE COLLECTION ZMSCA80038 is an Aflas O-ring designed for static and dynamic sealing applications across HVAC, refrigeration, plumbing, and industrial systems. It measures 2.625 inches inside diameter and 2.75 inches outside diameter, with a cross-section thickness of 0.0625 inches (1/16 inch), conforming to Dash 038 sizing. The Aflas material delivers a Shore A hardness of 80, placing it in the hard hardness category. This O-ring operates across a wide temperature range of 25 to 450 degrees F, making it suitable for high-heat and refrigeration environments where standard nitrile or EPDM compounds would degrade. Licensed HVAC technicians, plumbers, and industrial mechanics are the typical end users.

This O-ring is suited for residential and commercial sealing applications involving refrigeration fluids, hydraulic oils, fuels, brake fluids, acetic acid, animal oils, and bases. Its Aflas compound provides moderate resistance to petroleum products along with good ozone and weather resistance, making it a reliable choice for outdoor or chemical-exposure environments. It is particularly well regarded for sealing refrigeration fluids including Freon-type refrigerants, which makes it a common replacement seal in HVAC and refrigeration service work. Each package contains 4 O-rings.

Key Features

• Aflas material with 80 Shore A hardness for firm, reliable sealing under pressure
• Wide service temperature range: 25 to 450 degrees F
• Excellent for sealing refrigeration fluids including Freon-type refrigerants
• Good ozone and weather resistance for outdoor and harsh-environment use
• Moderately resistant to petroleum products, fuels, hydraulic oils, and brake fluids
• Round cross-section profile conforming to Dash 038 standard sizing

Compatibility

Compatible with systems and fluids including acetic acid, animal oils, bases, brake fluids, fuels, hydraulic oil, and refrigeration fluids. Designed as an OEM-style replacement O-ring for Dash 038 groove dimensions in HVAC, refrigeration, and industrial fluid-handling equipment.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics. Always depressurize and isolate the system before removing or installing seals, and verify that all refrigerant or fluid has been safely recovered or drained per applicable codes. Inspect the groove for burrs or damage before seating the O-ring, and apply a compatible lubricant to ease installation without stretching or twisting the ring. Confirm system pressure ratings are within the O-ring application limits before returning the system to service.
