2-Inch Pipe Insulation for HVAC Systems

This Nomaco Kflex 6RX048238 insulation fits 2-inch pipes with a 1/2-inch wall thickness and six-foot length. The NBR/PVC elastomeric material suits commercial and residential HVAC, plumbing and refrigeration lines. It is sold unslit for custom on-site cutting.

Temperature Range and R-Value Constraints

The insulation operates from -297 degrees F to 220 degrees F with an approximate R-value of 2.7. These limits define its practical use in extreme cold or high-heat piping. Installers must verify that system temperatures stay within this window.

Six-Foot Length and Wall Thickness Coverage

Each piece covers six linear feet of 2-inch nominal pipe with consistent half-inch wall thickness. Longer runs require multiple lengths joined on site. The unslit format adds installation time but allows precise fitting around fittings and valves.

Questions about this item

Should I pick the 6 ft length or a different size for my 2" pipe?

The 6 ft length covers a standard run and the 1/2" wall fits a 2" pipe with a 2 3/8" nominal ID.

What does the R‑value 2.7 tell me once the insulation is installed?

It means the material resists heat flow at that level, helping keep pipe contents near temperature between ‑297 °F and 220 °F.

How does the NBR/PVC elastomeric construction affect temperature limits?

The NBR/PVC blend is rated for continuous use from ‑297 °F up to 220 °F without degrading.
