Mastercool 83272 R1234yf 2-Way Piston Valve Manifold Gauge Set

Description

The Mastercool 83272 R1234yf 2-Way Piston Valve Manifold Gauge Set is engineered for precise diagnostics, charging, recovery, and evacuation of R1234yf automotive A/C systems. Because it uses free-floating piston valves, the manifold reduces O-ring wear while providing smooth, consistent valve action during service.

This set features anti-flutter gauges that steady needle movement for easier reading. In addition, clear temperature scales on the gauge faces help technicians interpret system conditions quickly. The aluminum manifold block integrates an extra-large sight glass, allowing visual checks of refrigerant flow during service.

Designed to meet current standards, the manifold assembles with (3) 12mm-F ports and includes nylon barrier hoses with 12mm-M fittings that comply with applicable SAE requirements. R1234yf high- and low-side couplers include extended disconnect protection sleeves, helping ensure safe connection and disconnection during automotive A/C work.
