Refco 4-Wege Monteurhilfe mit Koffer, SM4-3-DS Multi

4-valve test fitting complete with case, for R22, R134. The 4-way installation aid is a high-quality measuring instrument. The two Kl. 1.0 manometers, high-pressure side (red) -1 to +30 bar and low pressure side (blue) -1 to +10 bar can be adjusted to zero. Refrigerant temperature scales on the dials. Interchangeable piston valves guarantee a perfect seal. The hose connections hang freely from the aid (screws on the system side) and if not in use can be screwed to the side connections and the centre T-piece. This protects the thread from getting dirty and becoming damaged. With refrigerant scales for R22, R134a, R404A and R407C.
