Mastercool MC-53010-AUT Automotive Pressure Testing Regulator Kit

Description

The Mastercool MC-53010-AUT Automotive Pressure Testing Regulator Kit is a professional-grade tool set designed for leak testing automotive air conditioning and HVAC systems that do not contain refrigerant. By using an inert nitrogen supply, this kit allows technicians to safely pressurize empty systems and identify leaks without introducing refrigerant.

Built around a single-stage nitrogen pressure regulator with CGA580 US standard fittings, the kit provides controlled and accurate pressure delivery. Large, easy-to-read 2½-inch gauges with protective guards display both high- and low-side pressures clearly, while the ergonomic T-handle allows smooth pressure adjustment.

Packaged in a durable blow-molded carrying case, the MC-53010-AUT kit is well suited for shop and mobile service environments. Whether performing routine maintenance or diagnosing complex leaks, this kit helps technicians deliver accurate, efficient, and safe service.
