Aeroflex A3412 Pipe Insulation 0.75x0.5in R-3.1

Product Description

The AEROFLEX A3412 is a flexible closed-cell elastomeric pipe insulation designed to reduce heat gain, prevent condensation, and control energy loss on piping systems. With an R-value of 3.1, this product provides thermal resistance suitable for both hot and cold pipe applications. The A3412 fits pipe with a 0.75-inch outer diameter and features a 0.5-inch wall thickness. It is typically installed by HVAC technicians, plumbers, and mechanical insulation contractors on refrigerant lines, chilled water piping, domestic hot water lines, and other mechanical system piping.

This insulation is suited for residential and light commercial mechanical systems where pipe surface temperatures require thermal protection or condensation control. Common applications include split-system refrigerant line sets, fan coil unit piping, and domestic water distribution lines. The flexible elastomeric construction allows the material to be fitted on straight runs and moderate bends without cracking or deforming during installation.

Key Features

• R-3.1 thermal resistance rating for effective energy control on hot and cold lines
• 0.75-inch inner diameter fits standard nominal pipe and tubing sizes
• 0.5-inch wall thickness provides condensation control on chilled water and refrigerant piping
• Flexible closed-cell elastomeric construction resists moisture absorption
• Suitable for both hot and cold pipe insulation applications

Compatibility

Designed as a standard elastomeric pipe insulation for 0.75-inch outer diameter pipe and tubing in residential and light commercial HVAC, plumbing, and mechanical piping applications.

Installation Notes

Installation is typically performed by licensed HVAC technicians or mechanical insulation contractors. Shut down and isolate the piping system before applying insulation to ensure the pipe surface is clean, dry, and within the recommended temperature range for adhesive bonding. Longitudinal seams and butt joints should be sealed with a compatible elastomeric insulation adhesive to maintain thermal and vapor barrier continuity. Follow local mechanical codes and manufacturer adhesive guidelines for joint sealing requirements.
