Aeroflex AC1434 Pipe Insulation 1/4 in Wall 3/4 in Id

Product Description

The AEROFLEX AC1434 is a flexible closed-cell elastomeric pipe insulation designed to reduce heat gain and condensation on refrigerant, chilled water, and cold water piping. With a 3/4-inch inner diameter and a 1/4-inch wall thickness, it fits standard small-diameter pipe and tubing used in residential and light commercial HVAC and plumbing systems. HVAC technicians and plumbers install this material directly over copper or plastic pipe to maintain system efficiency and prevent moisture-related damage to surrounding structures.

This pipe insulation is suited for refrigerant suction lines, chilled water lines, and domestic cold water piping where condensation control is a priority. The 1/4-inch wall is appropriate for applications with moderate ambient conditions and low to medium temperature differentials. It is commonly used in residential split systems, mini-split installations, and light commercial cooling equipment where compact insulation coverage is needed on smaller pipe runs.

Key Features

• Closed-cell elastomeric construction resists moisture vapor transmission and condensation buildup
• 3/4-inch inner diameter fits standard small-diameter refrigerant and water pipe
• 1/4-inch wall thickness provides thermal protection in moderate-temperature applications
• Flexible material conforms to bends and fittings without cracking or splitting
• Lightweight construction simplifies handling and installation in tight spaces

Compatibility

Designed as an OEM-style replacement and new-installation insulation for 3/4-inch outer diameter pipe and tubing used in residential and light commercial HVAC, refrigeration, and plumbing systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or plumbers. De-energize and isolate the system before working on refrigerant or chilled water lines. Slide insulation over pipe before connections are made where possible, or slit lengthwise and apply adhesive to seal the seam. Follow local mechanical codes for required insulation thickness and vapor barrier continuity.
