Atco Rubber Products 010-R4.2_9X5FT Pipe Insulation Sleeve R4.2

Product Description

The ATCO RUBBER PRODUCTS 010-R4.2_9X5FT is a fiberglass pipe insulation sleeve designed for insulating round ductwork and pipe in indoor HVAC applications. It carries an R4.2 thermal resistance value and wraps pipes up to 9 inches in diameter in a flat blanket form. The insulation core is dense fiberglass, and the exterior jacket is a reinforced metalized polyester vapor barrier that limits moisture intrusion. Each section measures 5 feet in length, reducing the need for field cutting and speeding up installation. A starter cap is included. Licensed HVAC technicians and sheet metal contractors typically install this product on supply and return air duct systems.

This sleeve is rated for indoor use in residential and light commercial HVAC systems. The flat, pre-cut 5-foot sections are suited for wrapping flex duct connections, rigid duct transitions, and exposed pipe runs where code or design calls for continuous insulation coverage. The reinforced vapor barrier jacket resists tearing during handling and installation. The UL 181B listing confirms the assembly meets recognized standards for closure systems used with flexible air ducts and air connectors, making it appropriate where code compliance documentation is required on the job.

Key Features

• R4.2 thermal resistance rating for effective heat loss and gain reduction
• Fiberglass insulation blanket construction rated from -20 degrees F to 250 degrees F
• Reinforced metalized polyester vapor barrier jacket limits moisture penetration
• Pre-cut 5-foot flat sections reduce in-shop and jobsite cutting time
• Includes starter cap for a complete installation assembly
• UL 181B listed for use in indoor HVAC duct and pipe applications

Compatibility

Designed as an OEM-style insulation sleeve for 9-inch diameter pipe and ductwork in indoor HVAC systems where R4.2 insulation and a reinforced vapor barrier jacket are specified.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors. Power down the air handling system and ensure the duct or pipe surface is clean and dry before applying the sleeve. Secure all seams and overlaps using UL 181B-rated tape or closure systems per local mechanical code requirements. Do not compress the fiberglass blanket below its rated thickness, as compression reduces the effective R-value.
