Purpose-built pipe insulation for 1-1/2 inch lines

Nomaco Kflex 6RX048200 is a six-foot length of unslit elastomeric foam designed to wrap 1-1/2 inch pipe. The black NBR/PVC material suits plumbing professionals and facility managers who need reliable thermal protection on drain components.

Fits standard 1-1/2 inch pipe with a half-inch wall

The insulation carries a nominal inside diameter of two inches and a wall thickness of one-half inch, allowing it to slide over the target pipe without additional fittings. Its unslit construction means the installer decides where to cut, reducing waste on non-standard runs.

Holds rated performance from minus 297 to 220

Across that temperature span the foam maintains an approximate R-value of 2.7, limiting heat loss or gain on continuous hot-water returns or cryogenic lines. The elastomeric blend resists moisture absorption, so thermal efficiency does not degrade during prolonged exposure to condensation or ambient humidity.

Questions about this item

Will the 2.7 R-value hold up on a 6 ft run of 1-1/2" pipe in continuous service?

The 2.7 R-value is the nominal rating for the 1/2" wall thickness; it does not degrade with length, so the full 6 ft section maintains that insulation value.

Does the NBR/PVC elastomeric material stay flexible and quiet when hot water runs all day at 220 °F?

The NBR/PVC blend is rated from -297 °F to 220 °F, so it remains flexible and does not transmit noise at the top of its temperature range.

What pipe diameter must I already have for this 2 in nominal I.D. insulation to fit?

It is sized for 1-1/2" pipe; the 2 in nominal I.D. slips over that outside diameter without additional fittings.
