Area of use

Monoblocco is used to connect PEX pipes with MMA products.
The fitting is used in heating-and cooling systems.


Monoblocco is a complete fitting, with no loose details. This means that you do not need to preassamble the nut and cone.

Cut the pipe and make it free from grades. Mount by pushing the pipe into the bottom of the fitting.

M22x1,5 fits MMAs products that have M22x1,5 connections to, for example distributors, valves and couplings. The coupling is marked for the connection type.
The fitting is also tested to fit Pex according to ISO standards specified under technical info. The pipes must be according to the dimensions indicated by the technical info on the fitting.
For example 16×2 is a pipe with 16 mm outer diameter and 2 mm material thickness.
