Aeroflex A15812 Pipe Insulation 1-5/8 in 1/2 in Wall

Product Description

The AEROFLEX A15812 is a flexible elastomeric pipe insulation sleeve designed to limit heat gain and condensation on refrigerant, chilled water, and domestic cold water piping. With a 1-5/8 inch inner diameter and a 1/2 inch wall thickness, it provides a close-fitting, continuous thermal barrier around the pipe surface. The closed-cell foam construction resists moisture absorption and vapor transmission, keeping the pipe exterior dry and reducing the risk of corrosion or drip damage in mechanical systems. Licensed HVAC technicians and plumbers install this product during new construction and retrofit work where piping must meet energy code insulation requirements.

The A15812 is suited for residential and light commercial mechanical systems where 1-5/8 inch OD piping is present, including refrigerant suction lines, chilled water supply and return lines, and domestic cold water runs in conditioned or unconditioned spaces. The 1/2 inch wall thickness meets common insulation depth requirements for many jurisdictions following ASHRAE 90.1 and IECC guidelines. It is appropriate for both indoor and indoor-exposed installations where flexible, slip-on insulation is preferred over rigid board or fiberglass wrap.

Key Features

• 1-5/8 inch inner diameter fits standard refrigerant and chilled water pipe sizes
• 1/2 inch closed-cell foam wall limits heat gain and controls surface condensation
• Flexible elastomeric construction allows easy routing around bends and fittings
• Closed-cell structure resists moisture vapor absorption without a separate vapor barrier
• Continuous sleeve design eliminates seams along the pipe run when properly applied

Compatibility

Designed as an OEM-style elastomeric insulation sleeve for 1-5/8 inch OD piping used in residential and light commercial HVAC, refrigeration, and plumbing applications.

Installation Notes

Licensed HVAC technicians and plumbers typically install elastomeric pipe insulation as part of new piping runs or insulation upgrades. Isolate and depressurize the piping system before working on active refrigerant or chilled water lines. Apply manufacturer-approved contact adhesive to all longitudinal seams and butt joints to maintain vapor seal integrity at connections. Follow local energy codes and ASHRAE 90.1 insulation thickness tables to confirm this wall thickness meets requirements for the specific pipe service temperature and diameter.
