3-way pressure gauge set ZR-M30336A

3-way pressure gauge set ZR-M30336A for refrigerant charging R404A/R407C/R22/R134a

3-way pressure gauge set ZR-M30336A is an indispensable piece of equipment for HVAC technicians, refrigeration specialists and air conditioning service. This professional kit allows for pressure checking, refrigerant charging and monitoring of the freon recovery process in real time.

Constructed of durable materials and equipped with a corrosion-resistant brass manifold, this gauge set offers high reliability and excellent accuracy when working with refrigerants such as R407, R417a, R404, 134a, R22

Main advantages of the ZR-M30336A model

• Compatible with multiple refrigerants
• Solid copper and brass construction
• Large, easy-to-read 2-1/2” gauges
• High pressure resistant hoses
• Transparent visor for monitoring charging
• Ideal for air conditioning and commercial refrigeration service

Professional construction and high reliability

The valve body is made of integrated copper, which ensures corrosion resistance and a long service life. The ergonomic aluminum handles allow precise flow adjustment and comfortable use even in intensive working conditions.

3-way pressure gauge set ZR-M30336A includes two colored pressure gauges:

• Blue pressure gauge for low pressure: -30 ~ 260 PSI (-1- 30 bar)
• Red high pressure gauge: 0 ~ 500 PSI (0-35 Bar)

Colored scales and large dials make it easy to quickly read pressure values.

Durable hoses and standard SAE connections

The kit comes with 3 colored hoses approximately 1.8 meters long, made of wear-resistant and high-pressure composite material. The maximum working pressure is 500 PSI, and the burst pressure reaches 3000 PSI.

Standard connections 1/4″ SAE allow compatibility with most vacuum pumps, freon cylinders and professional HVAC equipment.

Precise monitoring of freon charge

The integrated transparent sight glass and sensitive indicator allow you to observe the refrigerant charging and recovery process. This helps to avoid system overload and increase the efficiency of the refrigeration system.
