Aeroflex AC13834 Pipe Insulation 1-3/8 X 3/4 Inches

Product Description

The AEROFLEX AC13834 is a flexible closed-cell pipe insulation sleeve designed to reduce heat gain and prevent condensation on refrigerant and chilled water piping. Manufactured under the Aerocel line, this insulation fits 1-3/8 inches outside diameter pipe with a 3/4 inch wall thickness. It is commonly installed by HVAC technicians and refrigeration mechanics on suction lines, chilled water lines, and other low-temperature piping where moisture control and thermal efficiency are critical to system performance.

This pipe insulation is suited for residential and light commercial HVAC and refrigeration applications. It is used on exposed and concealed piping runs where condensation control is a priority. The 1-3/8 inch ID fits standard refrigerant suction line diameters common in split-system air conditioning and heat pump installations. Field installation is straightforward, making it a practical choice for new construction and retrofit work alike.

Key Features

• Closed-cell foam construction limits moisture absorption and vapor transmission
• Fits 1-3/8 inch outside diameter pipe with 3/4 inch wall insulation thickness
• Flexible material conforms to piping layouts including bends and offsets
• Designed for condensation control on chilled and refrigerant suction lines
• Lightweight sleeve construction simplifies handling and installation

Compatibility

Designed as an OEM-style replacement and standard-fit insulation sleeve for 1-3/8 inch outside diameter refrigerant and chilled water piping commonly found in residential and light commercial HVAC and refrigeration systems.

Installation Notes

Installation is typically performed by licensed HVAC or refrigeration technicians. The system should be shut down and all piping depressurized before insulation is applied or replaced. Slit the sleeve lengthwise to slide over existing piping, then seal seams with a compatible closed-cell foam adhesive to maintain vapor barrier integrity. Follow local mechanical codes for insulation thickness requirements on refrigerant piping.
