1" pipe insulation, 6 ft length

Nomaco Kflex 6RX100138 is a closed-cell elastomeric pipe insulation designed for 1-inch copper or iron pipe. The unslit tubular sleeve measures six feet long with a one-inch wall thickness. It suits hot and cold plumbing lines in residential and commercial installations.

Indoor plumbing runs needing thermal protection

This insulation fits contractors and facility managers who want to reduce heat loss and prevent condensation on 1-inch piping. It is not suited for outdoor exposed runs without a protective jacket or for pipe sizes other than the stated nominal diameter.

Temperature range -297 °F to 220 °F

The material withstands extreme low-temperature and moderate high-temperature service across the stated range. This single specification determines whether the product matches the operating conditions of the intended piping system.

Questions about this item

How does the R-value of 6.8 perform once the insulation is installed on a pipe?

The R-value of 6.8 indicates the material's thermal resistance, helping to maintain fluid temperature and reduce heat loss or gain on the pipe.

What does the temperature range of -297 to 220 degrees F mean for the insulation material?

The NBR/PVC elastomeric material remains flexible and effective across a wide range from -297 °F to 220 °F without degrading.

What pipe and tube sizes does the 1-inch wall insulation fit?

It fits a 1-inch pipe size and a 1 3/8-inch tube size with a nominal inside diameter of 1 3/8 inches.
