Nomaco Kflex 3in Pipe Insulation

The Nomaco Kflex 6RX048348 is a black NBR/PVC based elastomeric pipe insulation designed for 3 inch pipes. It comes in a 6 foot length with a 1/2 inch wall thickness. It suits plumbers and facility managers needing thermal protection for hot or cold piping systems.

Temperature Limits and R-Value

The insulation operates across a temperature range from -297 degrees F to 220 degrees F. It carries an approximate R-value of 3.0. These figures define the practical thermal boundaries for the material in standard plumbing applications.

Unslit Installation Notes

The product is supplied unslit, so the installer must cut it lengthwise to fit over existing pipework. A sharp knife and accurate measurement are required to avoid gaps. The black elastomeric material can be sticky in warm conditions, which sometimes complicates a clean join.

Questions about this item

How do I pick the right insulation size for my pipe?

Choose this model when you need a 3 in nominal pipe size with a 1/2 in wall thickness and a 6 ft length; the nominal inside diameter is 3 1/2 in.

What does the R-value of 3.0 mean once the insulation is installed?

An R-value of 3.0 indicates the thermal resistance of the 1/2 in thick NBR/PVC foam, reducing heat loss or gain on the 3 in pipe it covers.

What temperature range can this NBR/PVC insulation handle in practice?

The material is rated from -297 Degrees F up to 220 Degrees F, so it suits both cryogenic and hot-water lines within those limits.
