BENEFITS OF VIEGA PRESS TECHNOLOGY
Press Tech Marine
Icon Safer

Eliminate Hot Work

Viega press fittings require no open flames or hot work permits which means all the trades can work together at the same time, allowing the project to get done – fast.

Faster Icon

Faster, Consistent Connections

A simple 11 joint assembly takes just under 11 minutes to press*. Compare that to more than two-and-a-half hours of welding and you’re talking about some serious cost savings.

Icon Plumbing Design

Reliable + Quality Installation

Unlike groove 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.

Icon Flexible Design

Faster System Commissioning

With Viega press fittings, you don't need to flush the system or perform environmental testing during install. Pressure testing can be completed immediately.

THE VIEGA DIFFERENCE

Viega press fitting systems are engineered to last the life of the system while delivering unrivaled consistency press-after-press. Viega fittings are secured with stainless steel grip 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 pipe connections have been made and false positives are a thing of the past.
