Viega products can be found all sorts of places – anywhere from pharmaceutical plants and breweries to high-rise condos, mines and ships.

We pride ourselves on this versatility of our pressing systems. We design and engineer our products to meet the greatest number of applications and we pursue approvals and certifications in order to make the benefits of pressing available for our customers in as many situations as possible.

Of course, most contractors don’t use Viega press systems for all the applications for which they’re approved, but it’s important to be aware of them in case the opportunity arises.

Take the ProPress copper system, for example.

ProPress is probably most commonly used for potable water, but it is approved for many other applications:


• Hot and cold potable water
• Rainwater/graywater
• Chilled water
• Hydronic heating water
• Fire sprinkler
• Steam (low-pressure, residential)


• Ethanol
• Lube oil
• Heating fuel oil
• Diesel fuel


• Compressed air
• Nitrogen
• Carbon dioxide
• Carbon monoxide
• Argon
• Oxygen
• Hydrogen
• Vacuum

Special Media

• Acetone

Much of the versatility is due to the fact that Viega offers three different sealing elements: EPDM, FKM and HNBR. The elements’ individual properties allow for the wide range of applications. Of course, there are system operating conditions and restrictions on many of the applications. To learn more about ProPress, click here.
