Press connector fittings with connectors manufactured from non-​alloy steel 1.0308 for seamless, welded, galvanized, epoxy resin coated, industrially painted and black steel pipes in accordance with DIN EN 10255 (BS 1387) and DIN EN 10220.Sealing element:A cutting ring, a separator ring and an EPDM (polished black) profile sealing element are included in the bead of the press connector. The cutting ring cuts into the pipe during pressing and ensures a force-locked connection.During insertion of the pipe, and later during the pressing, the separator ring protects the sealing element from damage.Press connectors:The press connectors are equipped with the Viega SC-Contur, which is a safety technology approved by Kitemark, and ensures that the connection is guaranteed to be leaking in an unpressed state. In this way, inadvertently unpressed connections are noticed immediately during a leakage test.The connectors may only be pressed with Viega press machines with constant pressing force (e.g. Pressgun 5, Picco, Pressgun 4E/ 4B).Viega guarantees that unpressed connections are visible during a leakage test:With the wet leakage test in the pressure range from 0.1–0.65 MPa (1.0–6.5 bar).With dry leakage test in the pressure range from 22 hPa–0.3 MPa (22 mbar–3.0 bar).Viega MegaPress fittings are offered in +200 configurations, including:Elbows.Couplings.Reducers.Tees.Reducing tees.Threaded adapters.Unions.Features and benefits:Up to 60% less assembly time in comparison with other conventional connecting methods, such as welding or threaded and groove connections.Economical due to high time-saving during installation.Fire-proof, as flames and flue gases are not produced with cold press technology.Universal use. Presses thick-walled steel pipes, irrespective of whether the pipe is seamless, welded, uncoated, galvanized or resin-varnished.Applications:Closed cooling and heating circuits.Industrial and plant engineering.Systems for technical gasses (on request).Heating water for closed pump hot water heating systems in accordance with VDI 2035 sheet 1 and 2.Compressed air (dry) in compliance with the specification of the sealing elements being used, EPDM at oil concentration <25 mg/m³.Anti-freeze, cooling brines up to a concentration of 50%.The system is intended for use in industrial and heating systems and is a replacement for welded and threaded connections in new installations and repairs. It is not suitable for use in drinking water installations. For this reason, pipes and connectors are labelled with a black symbol stating 'not drinking water'.The piping system must not be used for fuel gases in accordance with DVGW G 260.

Press connector fittings with connectors manufactured from non-​alloy steel 1.0308 for seamless, welded, galvanized, epoxy resin coated, industrially painted and black steel pipes in accordance with DIN EN 10255 (BS 1387) and DIN EN 10220.

Sealing element:

A cutting ring, a separator ring and an EPDM (polished black) profile sealing element are included in the bead of the press connector. The cutting ring cuts into the pipe during pressing and ensures a force-locked connection.

During insertion of the pipe, and later during the pressing, the separator ring protects the sealing element from damage.

Press connectors:

The press connectors are equipped with the Viega SC-Contur, which is a safety technology approved by Kitemark, and ensures that the connection is guaranteed to be leaking in an unpressed state. In this way, inadvertently unpressed connections are noticed immediately during a leakage test.

The connectors may only be pressed with Viega press machines with constant pressing force (e.g. Pressgun 5, Picco, Pressgun 4E/ 4B).

Viega guarantees that unpressed connections are visible during a leakage test:

  • With the wet leakage test in the pressure range from 0.1–0.65 MPa (1.0–6.5 bar).
  • With dry leakage test in the pressure range from 22 hPa–0.3 MPa (22 mbar–3.0 bar).

Viega MegaPress fittings are offered in +200 configurations, including:

  • Elbows.
  • Couplings.
  • Reducers.
  • Tees.
  • Reducing tees.
  • Threaded adapters.
  • Unions.

Features and benefits:

  • Up to 60% less assembly time in comparison with other conventional connecting methods, such as welding or threaded and groove connections.
  • Economical due to high time-saving during installation.
  • Fire-proof, as flames and flue gases are not produced with cold press technology.
  • Universal use. Presses thick-walled steel pipes, irrespective of whether the pipe is seamless, welded, uncoated, galvanized or resin-varnished.

Applications:

  • Closed cooling and heating circuits.
  • Industrial and plant engineering.
  • Systems for technical gasses (on request).
  • Heating water for closed pump hot water heating systems in accordance with VDI 2035 sheet 1 and 2.
  • Compressed air (dry) in compliance with the specification of the sealing elements being used, EPDM at oil concentration <25 mg/m³.
  • Anti-freeze, cooling brines up to a concentration of 50%.

The system is intended for use in industrial and heating systems and is a replacement for welded and threaded connections in new installations and repairs. It is not suitable for use in drinking water installations. For this reason, pipes and connectors are labelled with a black symbol stating 'not drinking water'.

The piping system must not be used for fuel gases in accordance with DVGW G 260. The connectors may only be pressed with Megapress press rings and jaws.
