Aeroflex 15834 Pipe Insulation 1-5/8 in Id 3/4 in Wall

Product Description

The AEROFLEX 15834 is a flexible closed-cell foam pipe insulation section designed to reduce heat gain, prevent condensation, and limit energy loss on refrigerant and chilled water piping. With an inner diameter of 1-5/8 inches and a wall thickness of 3/4 inches, it fits standard copper and steel pipe sizes common in HVAC and refrigeration systems. HVAC technicians and mechanical contractors install this product during new construction or retrofit work where piping requires thermal and moisture protection.

This insulation is suited for residential and light commercial HVAC applications, including split-system refrigerant lines, chilled water distribution piping, and domestic cold water lines where condensation control is required. The 1-5/8 inch ID accommodates common nominal pipe and tubing sizes found in cooling system installations. It is applied in mechanical rooms, crawl spaces, attics, and exposed interior runs where insulation continuity is critical to system efficiency.

Key Features

• Closed-cell foam construction resists moisture absorption and vapor transmission
• 1-5/8 inch inner diameter fits standard refrigerant and chilled water line sizes
• 3/4 inch wall thickness provides meaningful thermal resistance for cooling applications
• Flexible material allows installation around bends and through confined spaces
• Compatible with copper and steel pipe commonly used in HVAC and plumbing systems

Compatibility

Designed as an OEM-style replacement or new-installation insulation for refrigerant suction lines, chilled water piping, and cold water supply lines with a 1-5/8 inch outer diameter pipe or tubing.

Installation Notes

Installation is performed by licensed HVAC technicians or mechanical contractors following local mechanical codes. Shut down the refrigeration or HVAC system and allow piping to reach ambient temperature before applying insulation. Slit the insulation lengthwise for retrofit installation over existing piping and secure seams with a compatible closed-cell foam adhesive to maintain vapor barrier integrity. Avoid compressing the wall thickness, as compression reduces thermal performance.
