Atco Rubber Products 010-R4.2_8X5FT Pipe Insulation Sleeve R4.2

Product Description

The ATCO RUBBER PRODUCTS 010-R4.2_8X5FT is a flat pipe insulation sleeve designed for indoor HVAC applications. It combines a thick fiberglass insulation blanket with a reinforced metalized polyester vapor barrier jacket to deliver an R-value of 4.2. Each section measures 8 inches in diameter and 5 feet in length, sized to fit standard large-bore duct and pipe runs without requiring field cutting. The pre-cut length reduces labor time compared to roll-applied duct wrap. HVAC technicians install this sleeve during new construction or retrofit work where thermal efficiency and vapor control on supply piping are required.

This sleeve is suited for indoor HVAC system installations where pipe insulation must meet UL 181B standards. The 5-foot section format is particularly useful on commercial and residential mechanical rooms and air handler connections where consistent insulation thickness across long straight runs is needed. The included starter cap supports a clean, finished installation at pipe terminations. The flat sleeve format allows straightforward field application without specialized tools.

Key Features

• R-4.2 thermal rating for effective heat loss and gain control on insulated pipe runs
• Reinforced metalized polyester vapor barrier jacket limits moisture intrusion
• Pre-cut 5-foot sections reduce in-shop and jobsite cutting time
• Flat sleeve design simplifies installation compared to duct wrap application
• Rated for temperatures from -20 degrees F to 250 degrees F
• Includes starter cap for finished termination at pipe ends

Compatibility

Designed as an OEM-style replacement and standard-fit insulation sleeve for 8-inch indoor HVAC pipe and duct applications meeting UL 181B requirements.

Installation Notes

Installation is typically performed by licensed HVAC technicians. Power down the air handling system and allow surfaces to reach ambient temperature before applying insulation. Ensure the pipe or duct exterior is clean and dry before fitting the sleeve to achieve proper vapor barrier adhesion and thermal performance. Installations must conform to applicable local mechanical codes and UL 181B listed system requirements.
