VIEGA

INDUSTRIAL PIPING SYSTEMS


Your end-to-end industrial piping solution 

Viega press fittings and valves have more approvals than any press fitting manufacturer in the industry.
That means that from 1⁄2" all the way up to 4" in multiple alloys, including stainless steel, you have all the configurations you need. Viega press technology lets you make safe, secure connections in seconds – without a flame. And our Smart Connect® technology instantly identifies unpressed connections – so you can build and commission on the same day. If MRO is the name of your game, Viega helps you make repairs in seconds.

Benefits of Viega Press Technology

Benefits of Viega Press Technology
MegaPress fitting

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.

Lock Icon

Reliable + Quality Installation

Unlike grooved 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.

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.

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 press fittings reduce install time by up to 90%.




Approval of nonstandard applications requires chemical compatibility submission
