Mastercool 53004 Nitrogen Pressure Regulator – AS2473.2 Australia

MC53004

The Mastercool 53004 Nitrogen Pressure Regulator is designed for HVAC/R and automotive air conditioning technicians who need a reliable regulator for nitrogen pressure testing. This Australian AS2473.2 model is suitable for pressurising empty systems to help locate leaks before refrigerant is added.

Using nitrogen for pressure testing allows technicians to check a system for leaks without charging it with refrigerant. This helps save time during installation, service and repair work, while also avoiding the need to recover refrigerant from a system that is being leak tested.

The MC53004 is a single stage nitrogen regulator with a 1/4" SAE flare outlet connection, control valve, T-handle pressure adjustment and protected 63mm gauges. Built for professional HVAC/R service use, it offers a working adjustment range of 30–1000 PSI / 2–70 Bar, making it a practical regulator for refrigeration, air conditioning, commissioning and maintenance work.
