Custom-made seals for hyperbaric testing equipment


Hyperbaric and pressure testing chambers are essential in ensuring the reliability of products working under subsea conditions or high-pressure situations.

Products are placed in the chambers, before water is injected and then pressured using pumps. By simulating high pressure environments, the products are tested to determine that they can function properly and operate safely in ‘real-life’ circumstances.

The chambers operate using cylinder and valve systems, all of which require sealing, and this is where FPE Seals can help.

Tyne Pressure Testing are a specialist hyperbaric testing, certification and subsea research facility based in the North East of England, that regularly use FPE Seals for their specific sealing needs.


Tyne Pressure Testing have nine hyperbaric vessels of varying capabilities, including one of the largest testing chambers in Europe, with an internal diameter of 2.5m and the ability to test to 450 bar.

Polymeric seals used within the equipment, ranging from 25mm to 1m diameter, are fundamental to ensuring that all runs smoothly. And so, the chambers undergo regular maintenance including seal replacement.
