VIEGA Nypel 35x6/4 GZ Profipress S — stainless steel press fitting, male reducer, 35x6 to 28x6 mm

VIEGA Nypel 35x6/4 GZ Profipress S is a stainless steel press fitting designed as a male reducer to join a 35x6 mm pipe with a 28x6 mm pipe using an external threaded connection. Intended for press installation systems, this reducer enables solder-free, reliable connections in potable water, heating and cooling circuits. The stainless steel construction provides corrosion resistance and mechanical strength suitable for professional plumbing applications.

Advantages

The stainless steel body ensures long-term resistance to corrosion and mechanical wear while maintaining dimensional stability under typical system temperatures and pressures. The Profipress S press connection delivers consistent, leak-proof joints without the need for soldering or welding, reducing installation time and occupational hazards. The integrated external thread on the reducer allows secure transitions between press-joined piping and threaded components or fixtures, offering installation flexibility.

Suitable for

• Potable water distribution systems
• Heating systems (radiators, underfloor heating circuits)
• Cooling and chilled water installations
• Transitions between press piping and threaded valves or fittings

Key specifications

• Material: stainless steel
• Connection type: press connection on pipe ends, external male thread on reducer
• Pipe sizes: reducer from 35x6 mm down to 28x6 mm
• Intended use: potable water, heating and cooling systems
• Assembly method: press installation, solder-free

How to use

Prepare both pipe ends by cutting square and deburring; ensure the outer diameter and wall thickness correspond to the stated 35x6 mm and 28x6 mm dimensions. Slide the appropriate Profipress-compatible pressing jaw over the fitting end and position the fitting fully onto the pipe until it seats on the stop. Execute the press cycle according to the press tool manufacturer's instructions to form the permanent joint. Apply standard pipe thread sealing methods on the external male thread where it will mate with a threaded component, following the requirements for the intended media (water, heating fluid).

Usage recommendations

Use matched pressing jaws and calibrated press tools designed for Profipress S fittings to ensure correct press geometry and joint integrity. Verify system pressure and temperature ratings before commissioning and follow local plumbing codes for installation, testing and disinfection of potable water systems.
