Review on 🔌 R134a AC Refrigerant Recharge Hose Kit: Pressure Gauge & Tap Dispensing Valve - Ideal for Automotive and Home Air Conditioners & Refrigerators by Keith Iverson

Doesn't work well on my car (Lincoln Mark VIII from 1997) but not only on that, so it may be the car and not the charging manifold. It appears to be an all metal construction, but I can't see the hardware under the clamps to be sure. My last was the EZ Chill brand which had plastic hardware and broke (admittedly after a few years of faithful service. It is NOT 36 inches long as the attachment states, more like around 14 inches).
