Aeroflex 498-ac1410 Pipe Insulation 1in Wall 1/4in Id Epdm

Product Description

The AEROFLEX 498-ac1410 is a closed-cell elastomeric pipe insulation tube designed for thermal and moisture protection on small-diameter piping in HVAC, refrigeration, and plumbing systems. Manufactured from a proprietary EPDM rubber elastomeric foam, it delivers an R-value of R10 with a wall thickness of 1 inch and an inside diameter of 1/4 inch. The unslit, tubular construction maintains a continuous vapor barrier around the pipe, limiting condensation and heat gain or loss. With a temperature rating spanning -297 to 257 degrees F, this insulation handles both cryogenic and high-temperature applications. Licensed HVAC technicians, refrigeration mechanics, and plumbers install this product as a primary pipe covering on new and retrofit systems.

The 498-ac1410 is suited for dual-temperature systems, hot and cold water piping, HVAC distribution lines, refrigeration suction and liquid lines, and variable refrigerant flow systems. Each stick is 6 feet long, sized to fit 1/4 inch outside-diameter copper tubing. The EPDM compound provides enhanced resistance to UV light and water vapor compared to standard NBR-based elastomeric foam, making it a preferred choice for outdoor or partially exposed mechanical installations where long-term durability matters.

Key Features

• Closed-cell EPDM rubber foam construction resists moisture absorption to 0.2 percent by volume
• Water vapor permeability of 0.03 perm-in maintains vapor barrier integrity on cold piping
• R10 thermal performance with wall thickness of 1 inch on 1/4 inch ID tubing
• Flame Spread Index of 25 and Smoke Developed Index of 50 meet common building code requirements
• Thermal conductivity of 0.237 to 0.252 BTU-in/hr-sq-ft-degrees F across the rated temperature range
• UV-resistant EPDM compound suitable for exposed or outdoor piping runs

Compatibility

Sized for 1/4 inch outside-diameter copper tubing. Suitable for use in dual-temperature systems, hot and cold water piping, HVAC refrigerant lines, refrigeration systems, and variable refrigerant system applications.

Installation Notes

Installation is typically performed by licensed HVAC technicians, refrigeration mechanics, or plumbers following applicable mechanical codes. Ensure the pipe surface is clean, dry, and free of burrs before sliding the unslit tube into position; adhesive closures or approved elastomeric insulation adhesive should be used at butt joints to maintain the vapor barrier. Do not stretch the insulation during installation, as thinning the wall reduces thermal and vapor performance. On refrigerant lines, verify the system is properly isolated and depressurized before any pipe modification work begins.
