Armacell armacell-t11834p Tube Insulation 1-1/8 in 3/4 in Wall

Product Description

The ARMACELL armacell-t11834p is a flexible closed-cell foam tube insulation designed to reduce heat gain and prevent condensation on refrigerant lines, chilled water piping, and domestic cold-water lines. Each section fits pipe with a 1-1/8 inch inner diameter and features a 3/4 inch wall thickness for effective thermal resistance. This product is sold in a box of 15 sections, making it practical for multi-line installations or larger service calls. HVAC technicians and plumbers rely on this type of insulation to maintain system efficiency and meet energy code requirements on both new installations and retrofits.

This tube insulation is suited for residential and light commercial applications where refrigerant suction lines, copper water lines, or small-diameter chilled piping require thermal protection. The 1-1/8 inch ID fits standard 1-1/8 inch OD copper tubing commonly found in split-system air conditioning and refrigeration installations. The 3/4 inch wall thickness provides meaningful insulating value in unconditioned spaces such as attics, crawlspaces, and mechanical rooms where ambient temperatures can significantly impact system performance.

Key Features

• 1-1/8 inch inner diameter fits standard 1-1/8 inch OD copper pipe or tubing
• 3/4 inch wall thickness for thermal protection and condensation control
• Closed-cell foam construction resists moisture absorption
• Box of 15 sections for efficient stocking and multi-line jobs
• Flexible material conforms to bends and offsets without cracking

Compatibility

Designed as an OEM-style replacement and new-installation tube insulation for 1-1/8 inch OD copper refrigerant lines, chilled water lines, and cold-water piping in residential and light commercial HVAC and plumbing systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or plumbers. Isolate and de-energize the system before working on refrigerant or water lines. Slit the insulation lengthwise to slip it over existing piping and use a compatible contact adhesive at seams and butt joints to maintain a continuous vapor barrier. Follow local energy codes and manufacturer guidelines for minimum wall thickness requirements in conditioned versus unconditioned spaces.
