Armacell ARMA-APT15812 Pipe Insulation 1.625in Id 0.5in Wall

Product Description

The ARMACELL ARMA-APT15812 is a flexible closed-cell foam pipe insulation section designed to reduce heat gain and condensation on refrigerant, chilled water, and HVAC piping systems. Each section fits pipe with a 1.625-inch inner diameter and features a 0.5-inch wall thickness, with each piece running 6 feet in length. A full carton contains 90 linear feet of coverage. HVAC technicians and mechanical contractors install this insulation during new construction and retrofit projects to maintain system efficiency and prevent moisture-related damage on cold-surface piping.

This insulation is suited for residential and light commercial HVAC and refrigeration applications where flexible, easy-to-install pipe insulation is required. It fits standard copper and steel piping used in split systems, chilled water lines, and other mechanical piping that requires thermal and condensation control. The 90-linear-foot carton quantity is practical for larger jobs or multi-unit installations where consistent insulation coverage is needed across multiple pipe runs.

Key Features

• 1.625-inch inner diameter fits standard pipe sizes used in HVAC and refrigeration systems
• 0.5-inch wall thickness provides thermal insulation and condensation resistance on cold-surface piping
• Each piece is 6 feet in length for straightforward handling and installation
• 90 linear feet per carton supports larger job site coverage requirements
• Flexible closed-cell foam construction conforms to pipe routing without cracking
• Manufactured in the United States

Compatibility

Designed as an OEM-style replacement and standard fitment for flexible foam pipe insulation applications on 1.625-inch inner diameter piping in residential and commercial HVAC, refrigeration, and mechanical systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or mechanical contractors. Ensure the pipe surface is clean, dry, and free of oil or debris before applying insulation to achieve a proper seal. Slit the insulation lengthwise if retrofitting over existing piping, and use compatible insulation adhesive at all seams and butt joints to prevent moisture infiltration. Follow local mechanical codes for minimum insulation thickness requirements on refrigerant and chilled water lines.
