INDUSTRIAL PIPE FITTING SOLUTIONS

Downtime? Not on our watch.

Downtime?
Not on our watch.

Over the last three years, 82% of manufacturing facilities have experienced unplanned downtime at an average hourly cost of $260,000 per hour*. Viega pipe pressing technology gets you up-and-running faster, ensuring downtime is kept to a minimum.

That’s because our fittings eliminate the need for hot work permits as well as the dangers of open flames and toxic fumes. Whether you’re doing scheduled plant maintenance or have an unplanned repair, Viega press fittings deliver the consistency and reliability you need to boost your overall equipment effectiveness.

Benefits of Viega Pipe Pressing Technology


No Flame Icon

Eliminate Hot Work
Soldering and welding equipment is responsible for nearly 1,200 fires causing $150 million dollars in property damage*. Viega press fittings require no open flames or hot work permits.


Time Saving 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.


Lock Icon

Reliable + Quality Installation
Unlike groove or threaded pipe connections that reduce pipe wall thickness, Viega fittings preserve pipe integrity and come factory assembled for maximum consistency and performance in the field.


Sand Glass Icon

Reduce Downtime
When unplanned downtime can cost hundreds of thousands of dollars every hour, you need a product that can get you up-and-running faster. Viega pipe fittings reduce install time by up to 90%.

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.
