Pressure Testing Service

At Northern Valve & Fitting Company Limited, we offer a specialist pressure testing service, with a primary focus on hydrogen hose assemblies. Our facilities are equipped to carry out high-precision tests using nitrogen gas up to 600 bar, ensuring each assembly meets the highest standards of safety and performance.

All hydrogen hoses are tested under water, providing a clear visual indication of any leaks or structural weaknesses. This method, combined with our calibrated pressure transducers, allows us to monitor both pressure and temperature with exceptional accuracy throughout the test cycle. Every assembly is verified to perform under its rated conditions—giving you total peace of mind in demanding applications.

Thanks to our two dedicated test rigs fitted with high-pressure gas pumps, we can handle assemblies of virtually any size and configuration. Whether it’s a single high-pressure test or a volume run for OEM supply, our experienced team ensures each test is carried out safely, efficiently, and in line with relevant industry guidelines.

If you require certified pressure testing for hydrogen systems or other critical gas applications, we’re here to support you with precision, speed, and expertise. Get in touch to find out more or request a test.
