Kaiflex ST Coil – 9mm & 13mm Closed-Cell Rubber Pipe Insulation
Kaiflex ST Coil is a flexible closed-cell elastomeric rubber insulation designed for reliable thermal insulation of pipework in heating, cooling, refrigeration, HVAC and plumbing systems.
Available in 9mm and 13mm insulation thicknesses with a range of pipe outside diameters, Kaiflex ST Coil is supplied in full continuous coils. The length of each coil varies depending on the insulation thickness and pipe size selected.
Key Benefits
- Closed-cell construction helps resist moisture ingress and condensation.
- Suitable for hot and cold pipework across a wide range of HVAC and building services applications.
- Flexible rubber construction allows straightforward fitting around pipework and installations.
- High resistance to water vapour transmission helps maintain the integrity of the insulation system.
- Continuous coil format can reduce the number of joints required compared with shorter insulation lengths.
- Available in 9mm and 13mm thicknesses with pipe OD options from 6mm to 28mm.
