Nitrogen Leak Connection Kit — Nitrogen for A/C Leak Testing

Pressure testing with nitrogen is the industry-standard method for detecting leaks before system recharge. The Nitrogen Leak Connection Kit gives you a clean, reliable gas supply for every test.

Dry Nitrogen Supply

The Nitrogen Leak Connection Kit provides a clean, moisture-free nitrogen supply essential for accurate A/C system pressure testing.

Leak Testing Precision

Using nitrogen for leak detection avoids contaminating the A/C system with refrigerant before a fault has been fully diagnosed.

Safe & Inert

Nitrogen is non-flammable and non-toxic, making it the safest choice for workshop pressure testing under all conditions.

Workshop Essential

The Nitrogen Leak Connection Kit is a vital part of any professional A/C workshop’s toolkit, used alongside a regulator and connection kit.

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 Nitrogen Leak Connection Kit 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 Nitrogen Leak Connection Kit 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.
