Nomaco Kflex 6RHFN068238 trap

Pipe insulation tube for 2 inch pipes

This Nomaco Kflex tube provides thermal protection for pipes with a 2 3/8 inch outside diameter. The 3/4 inch wall thickness creates an R-value of 4.2 for effective temperature control. Made from halogen-free Buna-N rubber, it operates reliably between -40 and 250 degrees Fahrenheit. The unslit tube design suits new installations where the pipe end is accessible.

Suits plenum spaces and high-temperature lines

The plenum rating and low flame spread index of 25 with smoke developed index of 50 meet commercial building requirements. The closed-cell foam structure resists moisture absorption on chilled water or refrigeration lines. Installers needing a pre-slit product for retrofit work on existing piping should look at alternative designs. The fixed 6-foot length also requires cutting for shorter runs.

2 3/8 inch inside diameter matches 2 inch pipe size

This specific dimension ensures proper fit on standard 2 inch nominal pipe with 2 3/8 inch outside diameter. The unslit installation style means the tube must slide over the pipe end during assembly. Verifying the pipe outside diameter against this 2 3/8 inch figure is the single check that confirms compatibility.
