Electrical connectors

SITEC Electrical connectors to transmit electrical measuring data as well as to feed and control the heating capacity in high-pressure vessels. Special custom-built designs are available on request.

Pressure max. 7.000 bar / 10.000 PSI
Temperature -50°C to +175°C

Electrical single connectors

Features and advantages

  • To transmit electrical measuring data as well as to feed and control the heating capacity in high-pressure vessels.
  • To connect control leads and to insert electrical measuring leads into high-pressure apparatus.
  • This self-sealing high-pressure lead is insulated and seals against the internal vessel pressure.
  • To connect the wires, the leads have two nuts on the outside and are shaped as tube OD 2 mm x ID 0.7 mm on the inside.
  • Different lengths L of the lead in the HP vessel with insulation are available. Standard length L is 50 mm. Please specify the required length with the order.
  • Operating temperature: –50°C to +175°C, current: max. 10 A, insulating resistance: >1011 Ohm.
  • Caution: Only to be used with non-conductive fluids or insulated conductors.
  • Complete electrical single connectors available for assembly in standard SITEC HP connections 1/4 HP, 3/8 HP and 9/16 HP.
  • Available from stock.


  • Special designs on request.

Electrical multiconnectors

Features and advantages

  • Electrical multiconnectors are available with an external O-ring seal or a Bridgman closure.
  • The sophisticated Bridgman closure is used in high-pressure and high-temperature applications. Based on the Bridgman principle, a pressure of approximately 50% above the internal pressure is generated in the packing rings. Therefore leakage is absolutely excluded.
  • The design of the electrical leads is identical with that of the single electrical connectors.
  • The external seal rings in both multiconnector models are in PTFE. Based on their high chemical and diffusion resistance these electrical connectors can be used in most applications.
  • All electrical multiconnectors are available with 1 to 7 electrical leads.
  • Dimensions of assembly on request.


  • Special custom-built designs are available on request.
