PreFiS-XL connects steel tubes purely mechanically without welding

Gain safety and comfort
Steel tubes can be joined together in a very confined space without welding.

Save time and effort
Our press fittings can be installed in a matter of seconds using a press tool and a pressure pump. This does not require any protective measures or post-processing.

You can rely on the highest quality
The multiple-certified tubes connection withstands the highest pressure loads
and is resistant to chemicals.

Optimize your process costs
Thanks to the many advantages PreFiS-XL can contribute to
the reduction of your process costs.

Reduce the number of your suppliers
We can supply you with press fittings and steel tubes from a single source.
In this way, we guarantee that the products fit together perfectly
and reduce your number of suppliers.
