Shell Fitting: the new patented Eurotis connection system

A solution for every system.
At Eurotis, we are committed to finding a solution for every installation requirement that can simplify the work of installers. We have therefore expanded our range of solutions by introducing a new patented sleeve joint system, designed for the installation of Eurotis PLT-CSST formable steel tubes in medium and large diameters: DN 25, DN 32, DN 40 and DN 50.
The system is based on a new series of clamp fittings, Shell fittings, which allow for quick, secure connections without the use of tools, simplifying installation and reducing assembly time on site.
A system designed for Eurotis PLT-CSST pipes
The new system is the result of a specific study on the characteristics of Eurotis corrugated tubes, with particular attention to two fundamental technical elements:
- the bending radius of the tubes
- the characteristic pitch of the corrugation
The analysis has led to the development of a solution that is exclusively compatible with Eurotis PLT-CSST tubes. This ensures a correct connection, high safety standards and long-term reliability.
Stainless steel bracelet: strength and durability
The central component of the Shell Fitting system is the connecting sleeve made of stainless steel, the same material used for Eurotis tubes.
Stainless steel guarantees:
- high corrosion resistance
- resistance to high pressures
- stability under thermal stress
- long-term durability
Thanks to these characteristics, the system is particularly suitable for applications in thermal power stations, industrial plants and systems that require high operating performance.
How do I install it?
The Shell Fitting coupling system is designed to facilitate the installer’s work because it has a semi-shell structure, which allows the fitting to be easily positioned on the tube. Closure takes place after the second corrugation at the end of the tube, ensuring stable and controlled fastening.
Shell Fitting: the mechanical seal
La tenuta meccanica è ottenuta tramite l’ancoraggio diretto tra il bracciale e la corrugazione della tubazione in acciaio. Questo principio costruttivo evita incisioni o ovalizzazioni della tubazione durante il serraggio del raccordo, preservandone l’integrità e contribuendo alla riduzione delle perdite di carico.
Le diverse configurazioni di Shell Fitting
The system is available in multiple configurations:

Bracelet for connecting
tube to tube

Male threaded connection

Female threaded connector
A range designed to offer application flexibility in systems with medium and large diameter tubes.
