Mastercool 53010 Nitrogen Pressure Regulator Testing Kit

Product Description

The MASTERCOOL 53010 is a nitrogen pressure regulator valve leak testing kit designed for HVAC and refrigeration technicians performing pressure testing, leak detection, and system commissioning with nitrogen. The kit centers on the MASTERCOOL 53001 nitrogen pressure regulator and pairs it with a 63 mm high-pressure gauge rated to 4400 PSIG (300 bar) and a low-pressure gauge rated to 1000 PSIG (70 bar). Both gauges include protective guards. The regulator features a 1/4-inch SAE flare outlet port, a control valve that maintains pressure on the regulator at all times, and a T-handle for easy pressure adjustment without additional tools.

This kit is suited for residential and light commercial HVAC service work where nitrogen is used to pressure-test refrigerant circuits, check for leaks before system startup, or purge lines during brazing operations. The included 48-inch yellow charging hose and leak testing adapter extend reach to system service ports. The kit ships complete in a blow-molded carrying case, making it practical for field service technicians who move between job sites. All components meet CE applicable standards.

Key Features

• High-pressure gauge rated to 4400 PSIG (300 bar) with protective guard
• Low-pressure gauge rated to 1000 PSIG (70 bar) with protective guard
• 63 mm gauge faces for clear, easy reading
• 1/4-inch SAE flare outlet port for standard HVAC hose connections
• Control valve holds pressure on regulator continuously during testing
• T-handle design allows tool-free pressure adjustment
• Blow-molded carrying case included for organized transport and storage

Compatibility

Designed for use with the MASTERCOOL 53001 nitrogen pressure regulator, which is included in the kit. The leak testing adapter and 48-inch yellow charging hose are compatible with standard 1/4-inch SAE flare service connections found on most residential and light commercial refrigerant circuit service ports.

Installation Notes

Nitrogen pressure testing must be performed by a qualified HVAC technician following local codes and the system manufacturer's maximum allowable test pressure. Always verify that the system is fully isolated and depressurized before connecting or disconnecting any fittings. Never use oxygen or combustible gas in place of nitrogen for pressure testing. Inspect all hose and adapter connections for damage before pressurizing, and never exceed the rated pressure of the lowest-rated component in the test circuit.
