Insul-Tube 6RX048118 1-1/8" OD 6 ft NBR/PVC pipe insulation

Insul-Tube 1-1/8" OD pipe insulation

This Insul-Tube product is a flexible NBR/PVC tube designed to insulate copper tubing with a 1-1/8 inch outside diameter. It comes in a six-foot length with a half-inch wall thickness and a closed-cell foam structure. The material carries a plenum rating and an R-value of 2.9 for thermal resistance.

Suitable for standard copper tube sizes.

Installers working with 3/4 inch nominal pipe or 1-1/8 inch copper tube sizes will find the unslit tube fits the intended application. The insulation operates between minus 297 and 220 degrees Fahrenheit. Buyers who need a different inside diameter, a slit version for retrofit, or a facing material should look at other options.

Half-inch wall thickness gives R-value 2.9

The half-inch wall provides the stated thermal resistance of 2.9, which determines the insulation performance for the specified pipe size. Flame spread index is 70 and smoke developed index is 95, meeting plenum requirements. Verify that the wall thickness matches the project specification before purchasing.
