Viega products make construction, maintenance and repairs easier for customers working on vessels with small spaces and with tight windows for work. With no need for flame or harsh chemicals, workers can use Viega fittings to make quick connections while other trades work alongside them.

Defense

Viega offers MegaPress CuNi, the only copper nickel press fitting with NAVSEA approval allowing shipbuilders and Navy personnel to better integrate fittings into onboard systems.

Commercial

Viega press fittings meet different approval needs for a variety of commercial marine projects.

Offshore

With a number of material types that work for most metric and standard pipe sizes, Viega press fittings work with tankers, bulkers, gas carriers and more.

Cruise/Passenger

Multiple sealing element options and fitting sizes make Viega press systems a trusted single supplier solution for the multiple needs for a cruise ship installation. 

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, 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.

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.

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.

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:

 

Approval of nonstandard applications requires chemical compatibility submission
