No Flame Icon

One Tool, Multiple Systems

Every Viega system – PureFlow, ProPress and MegaPress – can be pressed with a single tool.

Lock Icon

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.

Time Saving Icon

Press, Test, and Go

The Viega PureFlow PEX system can be tested immediately with air or water, allowing for labor and time savings.

Sand Glass Icon

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.

Smart Icon

Smart Connect

With Smart Connect technology, you can easily identify unpressed connections during system pressure testing and have 100% confidence each connection is complete.

Seismic Icon

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.

Whether you’re building a custom single-family home or constructing a large apartment complex, our residential options can make it all happen. 

Approved pplications include:

Potable Water Systems
Chilled Water Systems
Hydronic Heating Systems
Radiant Heating/Snow Melt Systems
Treated Water
Fuel Gas
Low-Pressure Steam
