BENEFITS OF VIEGA PRESS TECHNOLOGY
One Tool, Multiple Systems
Eliminate Hot WorkEvery Viega system – PureFlow, ProPress and MegaPress – can be pressed with a single tool.
Press, Test, and Go
The Viega PureFlow PEX system can be tested immediately with air or water, allowing for labor and time savings.
Smart Connect
With Smart Connect technology, you can easily identify unpressed connections during system pressure testing and have 100% confidence each connection is complete.
Reliable + Quality Installation
Unlike grooved or threaded connections that reduce pipe wall thickness, Viega fittings preserve pipe integrity. All of our fittings come factory assembled for maximum consistency in the field.
No Recovery Time Needed
Viega’s press and crimp piping solutions are not affected by environmental temperatures, so no matter the conditions your connections are ready immediately.
Seismic Certification
Viega is the first and only press manufacturer to be able to say its press products in copper, carbon steel, and stainless-steel including valves, have passed the highest U.S. seismic standards.
