Aeroflex 633-ac12112 Pipe Insulation 1/2 in Id 1-1/2 in Wall

Product Description

The AEROFLEX 633-ac12112 is a closed-cell EPDM rubber elastomeric pipe insulation tube designed for thermal and moisture control on mechanical piping systems. Manufactured unslit for a continuous, seamless fit, this tubular cover features a 1/2-inch inside diameter, a 1-1/2-inch wall thickness, and a 6-foot length per section. The EPDM rubber construction delivers an R-value of 14.4 along with exceptional resistance to UV exposure, water vapor transmission, and moisture absorption. Licensed HVAC technicians, plumbers, and mechanical insulation installers use this product where long-term thermal performance and environmental durability are required.

This pipe cover is rated for dual temperature systems, hot and cold water piping, HVAC refrigerant lines, and variable refrigerant flow systems. The 1/2-inch ID fits 1/4-inch IPS iron pipe and 3/8-inch copper tubing. Its broad temperature rating of -297 to 257 degrees F makes it suitable for both cryogenic and high-temperature piping applications in residential and commercial mechanical systems. The unslit construction is preferred when sliding insulation onto open pipe ends during new installation rather than retrofitting over existing piping runs.

Key Features

• Closed-cell EPDM rubber elastomeric foam construction resists moisture absorption at 0.2 percent
• R-value of 14.4 with thermal conductivity of 0.237 to 0.252 Btu-in/hr-sq-ft-degrees F
• Water vapor permeability of 0.03 perm-in limits condensation risk on cold piping
• Flame Spread Index of 25 and Smoke Developed Index of 50 meet standard fire performance requirements
• Wide temperature range of -297 to 257 degrees F supports refrigeration, HVAC, and hot water applications
• UV-resistant EPDM formulation suited for exposed outdoor or rooftop piping installations

Compatibility

Fits 1/4-inch IPS iron pipe and 3/8-inch copper tubing with a 1/2-inch inside diameter. Suitable for dual temperature systems, hot and cold water piping, HVAC, refrigeration systems, and variable refrigerant system applications.

Installation Notes

Installation is performed by licensed mechanical insulation contractors, plumbers, or HVAC technicians. Because this tube is unslit, it must be threaded onto pipe from an open end prior to final assembly or connection. All piping should be clean, dry, and free of sharp burrs before sliding the insulation into position. Use a compatible adhesive at butt joints and seams to maintain vapor barrier integrity, and consult local mechanical codes for required insulation thickness and flame-spread compliance.
