Common Questions

Frequently Asked Questions

Technical questions from technicians and workshop owners. If yours isn’t here, our team will answer it directly.

Nitrogen is used for pressure testing A/C systems for leaks before recharging. It is safe, dry, and inert — making it the preferred test gas for professional workshops.
Yes — always use a suitable pressure regulator when working with nitrogen. The Nitro-Trace NH 10 Bar Test Kit – Auto R134a+R1234yf is designed for use with a compatible nitrogen regulator and connection kit.
Testing pressure varies by vehicle manufacturer. Typically 150–200 PSI (10–14 bar) is used for automotive A/C systems. Always refer to the vehicle service data.
The nitrogen used for A/C leak testing is the same gas but must be supplied from a dedicated, dry cylinder. Never use a tyre inflation nitrogen source for A/C testing.
Cylinder duration depends on usage. A typical Nitro-Trace NH 10 Bar Test Kit – Auto R134a+R1234yf provides multiple system tests. Monitor the cylinder pressure gauge and replace when depleted.
No F-Gas qualification is required for nitrogen. However, working with pressurised gas requires appropriate training and risk assessment under COSHH and PSSR regulations.
