Armacell armacell-t3434p Tube Insulation 3/4 Id 3/4 Wall 23/box

Product Description

The ARMACELL armacell-t3434p is a flexible closed-cell foam tube insulation designed to reduce heat gain and condensation on refrigerant lines, chilled water piping, and domestic cold water supply lines. With a 3/4-inch inner diameter and a 3/4-inch wall thickness, this product delivers substantial thermal resistance suitable for residential and light commercial piping applications. Each box contains 23 pieces. HVAC technicians and plumbers install this insulation during new construction and retrofit projects to protect copper and other pipe materials from moisture accumulation and energy loss.

This tube insulation is used on refrigerant suction lines, chilled water lines, and cold domestic water piping in residential and commercial settings. The 3/4-inch ID sizing fits standard 3/4-inch nominal copper tube. The 3/4-inch wall thickness provides meaningful insulating depth for applications where condensation control and thermal performance are priorities. Installation is straightforward in exposed mechanical rooms, crawl spaces, and above-ceiling runs where pipe sweating or heat gain is a concern.

Key Features

• 3/4-inch inner diameter fits standard 3/4-inch nominal copper and compatible pipe
• 3/4-inch wall thickness for enhanced thermal resistance and condensation control
• Closed-cell foam construction resists moisture absorption
• 23 pieces per box for efficient stocking and jobsite use
• Flexible material allows installation on straight runs and gradual bends

Compatibility

Designed as an OEM-style replacement and new-installation tube insulation for 3/4-inch nominal pipe and tubing used in HVAC refrigerant, chilled water, and cold water plumbing systems.

Installation Notes

Licensed HVAC technicians and plumbers typically install closed-cell tube insulation as part of refrigerant piping or plumbing rough-in work. Ensure all pipe surfaces are clean and dry before sliding or slitting insulation into place. Use manufacturer-approved contact adhesive at seams and butt joints to maintain a continuous vapor barrier. Follow applicable mechanical codes for insulation requirements on refrigerant and chilled water lines.
