Viega fittings met the highest standards for seismic durability in recent testing at an earthquake simulation facility.
The fittings were tested at 200 psi with compressed gas and at 300 psi with water at the Structural Engineering and Earthquake Simulation Laboratory at the University at Buffalo in December 2021. The fitting assemblies withstood acceleration factors up to SDs 2.0 for at least 30 seconds. The United States Geological Survey considers a 2.0 certification to be the highest level required in the most seismically active areas of North America. That makes Viega the only fitting manufacturer whose press fittings have met the
