ProPress for Complete Peace of Mind and Reliability


Benefits of ProPress

All ProPress products carry the highest standards of excellence to offer a reliable and efficient performance. You can use Viega ProPress products with complete peace of mind because they never let you down. ProPress products are tested several times to ensure they offer topmost quality.

Your project can benefit on several grounds by using ProPress products. Let's explore some of the advantages to give you an idea of what's on offer.

Keeps Your Project on Schedule

You can complete your project even before time by using ProPress piping solutions. The innovative pipe joining method also contributes to time savings helping you make installations faster than traditional methods. ProPress installations reduce the need for callbacks and help contractors easily detect unpressed connections.

Many ProPress products can be pressed in a matter of seven seconds or less. You can also perform pressure tests immediately as there is no waiting for drying or curing. On average, ProPress systems can cut back the installation time by up to 60%. There's also no need to solder or weld the pipes which may get quite messy.

You are guaranteed to meet your deadlines every time using secure, reliable and convenient solutions from Viega.

Designed for Safety

ProPress products feature the patented Smart Connect technology to make room for a safe installation. The feature helps installers make sure that they have pressed all connection by running a simple low pressure water test. If you have missed any joints, you can quickly press it without having to drain the whole system.

ProPress products also come with cylindrical pipe guides so that pipes remain straight and protect the sealing element during installation. Normal fittings without cylindrical pipe guides can result in unsecured connections and damage to sealing element.

ProPress fittings are designed with distinct hexagonal pressing patterns that secure the pipe and fitting and offers mechanical strength for the connection. You can also secure a connection in a single move by pressing the sealing element in three ways.

The company also offers three different types of sealing element (EPDM, HNBR and FKM) for versatile applications.

Viega products even create a safe job environment and serve as environment-friendly solutions. You don't require any flames for your work which eliminates risks of toxic fumes and fires. The technology also helps you work without the need for fire watches or hot work permits.

The products also conserve the environment as you don't have to use any flux, solder, or gas.

Easy Installation

ProPress fittings and solutions are simple and safe to install compared to traditional methods. You can install the products anywhere, under any condition without facing problems.

Various design considerations help in easy installation of ProPress fittings. You don't need to alter the thickness of the pipe wall to get your desired connection like in the case of threaded and grooved connections. The fittings can also be pressed with simple tools without the need for fire or specialized gear.

You can also create connections wet or dry, for easy and quick repairs involving existing systems. The connections you make are also clean and professional, without any buildup of joining materials, tarnish or exposed threads.


You can find more than 600 engineered fittings from Viega in different materials, sizes and configurations. The products can be used for a variety of applications including drinking water, hot and cold water, plumbing, mechanical installations, gas, heating and more.

ProPress products are ideal for residential, commercial and industrial projects. So whether you are working on a portable water system or a corrosive chemical application, you can rely on ProPress products without any worries.

Security Under Pressure

Pressure testing your piping system is a crucial step to ensure everything is in order. The Smart Connect feature of ProPress products provides a quick and easy way to identify unpressed connections. The technology allows liquid or gases to escape from unpressed connections for easy tracking of locations that needs pressing.

We test your system with a water pressure of 15 to 85 psi and use 1/2 to 45 psi for air pressure testing. After we have successfully run connection tests, we increase the water pressure to 600 psi and air pressure to 200 psi for further testing as per local code requirements.

Strict Standards

Viega products and manufactured and tested to strict standards to ensure uncompromised performance and safety. All products meet or exceed the local and national codes and standards with full compliance with all laws.

For example, ProPress fittings for drinking water follow the updated requirements on lead content that came into effect in January 2014.

Some of the codes and standards followed by ProPress include :

  • NSF/ANSI 61: Drinking Water System Components - Health Effects
  • NSF/ANSI 61G: Lead Content Evaluation Procedure to satisfy less than or equal to 0.25% of average lead content
  • UL: Underwriters Laboratories
  • ABS: American Bureau of Shipping
  • CSA International: Canadian Standards Association
  • IPC: International Plumbing Code
  • UPC: Uniform Plumbing Code
  • PHCC: National Standard Plumbing Code
  • NFPA 13, 13D and 13R: Fire Sprinkler Applications
