Pipe insulation for 3-inch pipe

Nomaco Kflex 6RX068348 is a 6 ft length of unslit pipe insulation designed to fit a 3 in pipe size. The insulation body uses NBR/PVC based elastomeric material with a 3/4 in wall thickness. It has a nominal inside diameter of 3 1/2 in and an approximate R-value of 4.2. The product is black in colour and supplied new.

Suited for freeze protection

This insulation suits installers who need continuous thermal protection on straight runs of 3 in piping. It is not for buyers who require pre-slit or self-sealing insulation for faster installation. It is also not for applications where the operating temperature exceeds 220 °F or drops below -297 °F. The material carries a California Proposition 65 warning for reproductive harm.

Continuous service range -297 °F to 220 °F

The decisive specification is the wide temperature range of -297 °F to 220 °F, which determines whether the material survives the intended environment. Confirm that the system never exceeds these limits before specifying this insulation. The R-value of 4.2 and 3/4 in wall thickness support thermal performance within this envelope.
