The RGPH High Pressure Seal is for use in areas where extreme pressure tightness is required, i.e. the legs of offshore oil and gas platforms, subsea tie backs or between compartments in submarines. Approved for cable and pipe penetration in bulkheads or decks limited to a pressure of 66.7 bar water tightness.
The penetration system is generally not to be used for penetrating boundaries of tanks, but an approval
may be given on a case by case basis for penetration of boundaries of tanks limited to a pressure of 40

The RGPH system is available in six sizes designated based on the seal diameter (mm), RGPH-50, 70, 100, 125, 150 and 200.

  • Custom designed
  • Type approved to 66.7 Bar water pressure
  • DNV-GL and ABS type approved

The RGPH has a high grade tubular steel housing and the cables are individually sealed by insert blocks. The pressure seal is achieved by steel fittings and bolts.
The RGPH can be designed to let any amount of cables though. As it is built on a modular system the number of cables through the penetration can easily be increased or decreased.
Each RGPH is designed specially to the customers need.
The RGPH high pressure seal is available with flange for bolting or without flange for welding. The RGPH is frequently used in offshore installations and in different types of submarines.

Inspection and tests:

Dimensional and visual inspected before delivery. Additional tests can be performed to clients specification. It can be equipped with a tightness test function (semipermeable layer), which allows on site tightness testing after installation.

Certificates and reports:

• Factory Inspection and Test Report Certificate (optional).
• Material Test Certificate.
• Type Approved by DNV-GL and ABS for pressure up to 66.7 Bar.
• Approved in Tanks for pressure up to 40 Bar.


A detailed instruction manual is supplied with the RGPH.
