Pipe insulation for 2-5/8 in tubing

This Nomaco Kflex pipe insulation fits a 2-5/8 in tube size with a 3/4 in wall thickness and a 6 ft length. The NBR/PVC based elastomeric material provides thermal protection across a wide temperature range. It is supplied in black and comes unslit for custom fitting on site. The approximate R-value is 4.3.

Suits HVAC and plumbing runs needing continuous

Installers insulating long straight runs of 2-5/8 in pipe will find the 6 ft length efficient. The unslit tube requires cutting and sealing at joints, so it is less convenient for retrofit work on assembled systems with many fittings. Buyers who need pre-slit or self-sealing insulation should look at alternative designs.

3/4 in wall thickness drives thermal performance

The 3/4 in wall delivers an approximate R-value of 4.3 and supports operating temperatures from -297 to 220 degrees F. This single dimension determines whether the insulation meets the project's heat-loss or condensation-control requirements. Verify the specification against your design calculations before purchasing.
