Benefits of Viega Press Technology
Eliminate Hot Work
Viega press fittings require no open flames or hot work permits which means there is no need for additional manpower, plus you can skip the messy or labor-intensive tools.
Faster, Consistent Connections
Viega press fittings offer a variety of transition couplings to accommodate multiple piping materials to harness the features and benefits each has to offer where local codes allow. Transitions from Copper to PEX offers flexibility and absorbs expansion & contraction.
Reliable + Quality Installation
Viega fittings tested in 6 different seismic events in conjunction with ICC-ES AC 156, the most widely recognized testing procedure referenced in ASCE 7 and the International Building Code (IBC).
Reduce Downtime
Viega products can be pressed in seconds wet or dry, a significant time savings over traditional methods. There is no need to drain the full system and pressure tests can be performed immediately
Approved Applications
Viega ProPress and MegaPress systems are approved for a wide variety of standard applications including: water, fuels, oils, lubricants, and gases.
They are also approved for more than 2,500 nonstandard applications including:
| Potable Water Systems Chilled Water Systems Gas Systems Hydronic Heating Systems Radiant Heating/Snow Melt Systems Patio Gas | Treated Water Fire Sprinkler Natural Gas Low-Pressure Steam Reverse Osmosis Water Diesel Fuel |
Approval of nonstandard applications requires chemical compatibility submission
Certified in U.S.
Commercial buildings require reliable connections. That’s why we subject our systems to the strictest quality and performance testing - including burst, vibration, fire, and seismic. We also work directly with our customers to provide unique solutions to modern challenges.
As a result, Viega press systems have earned a litany of certifications from governing bodies across the US and abroad.
The Viega Difference
Viega press systems are engineered to last the life of the system while delivering unrivaled consistency press-after-press. Viega fittings are secured with stainless steel bite rings using over 5,000 pounds of force and include a separator ring, and sealing element outside of the flowpath to increase system lifespan and stand up to a broad range of pressures, temperatures, and applications. With smart connect technology, you can rest assured that all connections have been made and false positives are a thing of the past.

With press technology, contractors can significantly shorten downtime for repairs since there’s no need to entirely drain a system. There are no flames with press fitting pipe, so fire watch is unnecessary.
