FAQs

Are these fittings suitable for continuous pressure monitoring?

Yes. They are designed for both temporary and continuous monitoring in static and dynamic hydraulic systems.

How do I connect a pressure gauge to a Minimess coupling?

Use a compatible test hose or probe. The screw-to-connect interface ensures leak-free coupling without fluid loss.

Can these be reused?

Absolutely. They are built for repeated use without loss of integrity when properly maintained.

What if I need a thread size not listed?

We offer custom threading (e.g., BSPT, UNF, ISO) with low minimum order quantity.

Are pressure test certificates provided?

Yes. All couplings are pressure tested, and test reports or MTCs (EN 10204 3.1) can be issued on request.
