K-FLEX SOLAR HT Elastomeric Pipe Insulation Tube – 25m Coil
K-FLEX SOLAR HT in 25 metre coil format — ideal for longer runs and trade installations where continuous lengths reduce joints and improve installation speed. The same high-performance EPDM-based elastomeric foam as the 2m tube, rated for continuous service from -80°C to +175°C with full UV resistance for outdoor use.
Available in 13mm and 19mm wall thicknesses across 15mm, 18mm, and 22mm bore sizes — covering the most common solar thermal collector pipe dimensions.
Key Features
- 25 metre continuous coil — fewer joints, faster installation
- High-temperature elastomeric foam — continuous service up to +175°C
- Cold temperature performance down to -80°C
- UV-stabilised — suitable for outdoor installation without additional cladding
- Closed-cell structure — excellent moisture and vapour resistance
- Available in 13mm and 19mm wall thicknesses
- Bore sizes: 15mm, 18mm, 22mm
Typical Applications
- Solar thermal collector pipework — long continuous runs
- Heat pump flow and return circuits
- High-temperature HVAC and process pipework
- Outdoor pipework requiring UV-resistant insulation
