The ATCO RUBBER PRODUCTS 010-R4.2_6X5FT is a fiberglass pipe insulation sleeve designed for indoor HVAC system applications. It combines a thick fiberglass insulation blanket rated at R4.2 with a reinforced metalized polyester vapor barrier jacket. The flat, blanket-style construction wraps around 6-inch pipe and comes in pre-cut 5-foot sections, eliminating the need for in-shop or jobsite cutting. The vapor barrier jacket resists moisture infiltration, protecting the insulation core and maintaining thermal performance across a rated temperature range of -20 degrees F to 250 degrees F. A starter cap is included with the sleeve. HVAC technicians and mechanical insulation installers are the primary tradespeople for this product.
This sleeve is suited for indoor HVAC piping installations where thermal efficiency and vapor control are required. The pre-cut 5-foot length reduces labor time compared to field-cut duct wrap applications, making it practical for both new construction and retrofit work. The R4.2 thermal value meets energy code requirements common in residential and light commercial HVAC systems. The UL 181B listing confirms compliance with applicable duct and pipe insulation standards for indoor use.
Designed for use on 6-inch indoor HVAC piping as an OEM-style insulation sleeve where R4.2 thermal performance and a metalized vapor barrier jacket are required.
Installation is typically performed by licensed HVAC technicians or mechanical insulation contractors. Shut down and isolate the system before applying insulation to any active piping. Ensure pipe surfaces are clean and dry before wrapping to maintain jacket adhesion and vapor barrier integrity. Follow local mechanical codes and manufacturer instructions for sealing seams and terminations.
