Nitrogen regulator - Mastercool

Mastercool Nitrogen Pressure regulator

Mastercool 's nitrogen pressure regulator is specifically designed for leak testing of HVAC/R and automotive AC systems when the system does not contain refrigerant . The regulator is a single-stage nitrogen regulator that allows the system to be pressurized with inert nitrogen gas for fast, safe and efficient leak detection.

This is a time-saving and cost-effective tool for professional technicians who want to test systems without the use of refrigerant, UV dye or electronic leak detectors.

Effective leak testing without refrigerant

By pressurizing an empty system with nitrogen, leaks can be located quickly and precisely. Once the test is complete, the valve insert is easily removed to release the inert nitrogen gas in a controlled manner.

The regulator can be used on all applications requiring a 1/4" connection , including HVAC systems and refrigeration systems for R12, R22 and R134a.
