Product information

Description

VIEGA Mufa 18x3/4 GW Profipress S is a press-to-thread coupling engineered to connect 18 mm Profipress S copper or compatible pipe to a 3/4" female threaded fitting. The product is intended for potable water, heating and HVAC systems where a reliable transition from press-fit piping to a threaded connection is required. The design supports fast installation using a compatible pressing tool while providing a leak-resistant joint suitable for pressure-bearing applications.

Advantages

The coupling combines a pressed copper connection and a precision-cut female thread to reduce the need for additional adapters. Its construction ensures corrosion-resistant performance in typical plumbing and heating environments and reduces assembly time compared with soldered or brazed transitions. The press connection provides consistent sealing and mechanical stability when installed with the recommended Profipress S pressing profile.

Suitable for

  • Connecting 18 mm Profipress S copper pipe to 3/4" female threaded valves or fittings
  • Domestic and commercial potable water installations
  • Heating circuits and radiators requiring a press-to-thread transition
  • HVAC systems where a secure threaded interface is needed

Key specifications

  • Connection type: press-fit on one end, 3/4" female thread on the other
  • Pipe compatibility: 18 mm Profipress S copper or compatible pipe
  • Material: corrosion-resistant metal suitable for plumbing and heating use
  • Application: potable water, heating and HVAC installations
  • Sealing principle: press-fit joint designed for leak-resistant performance

How to use

Prepare the 18 mm copper pipe by cutting square and deburring the end. Slide the coupling over the pipe until it seats fully against the stop. Use a compatible Profipress pressing tool with the correct jaw/profile to make the press connection according to the tool manufacturer’s instructions. For the threaded end, apply the appropriate thread sealant or tape if required by the system design, then tighten the mating 3/4" male fitting or valve to the specified torque. Verify alignment and perform pressure testing following applicable codes and standards.

Usage recommendations

Use only approved pressing tools and jaws for Profipress S systems and follow local regulations for potable water and heating installations. Confirm material compatibility with system media and perform pressure and leak tests after installation. Avoid using the fitting in applications with aggressive chemicals or temperatures outside the validated range for Profipress S components.
