Fittings

Our PEX pipework has a whole range of fiitings and accessories.

PRESS fittings - tooling required.

HEAT INSULATION

Heat loss calculation: For the calculation of the heat losses for CaldoPEX single and double pipes, for the conductivity of the pu-foam is a mean value of 0.022 W/mK assumed. 

SHROUD SYSTEM

This new CaldoCLICK shroud system guarantees highest quality on construction site, without time-consuming bonding, shrinking or screwing, with secure connection technology and best thermal insulating properties.

Ideal to first time users. See our installation videos

PRESS FITTINGS

These are a very secure and the most popular method of connecting PEX pipe together. Tooling availible for sale and hire. Full training can be provided on site.
