AC Manifold Gauge Set for R134a R12 R22 R502 Refrigerant, Car Gauge Set With 5FT Hoses, Adapter, Adjustable Couplers, Puncturing & Self Sealing R134A Can Tap Freon Charge Kit

Worked great for diagnosing my wife's 2012 Nissan Murano and recharging her ac. Well worth the money.

Trae todo lo necesario

Used to fill car system w/ refrigerant. Easy to put together, sturdy parts.

The instructions presume an expert if proper use. What is NOT mentioned: There is a spool of teflon tape to enable tightened hoses. Wrap tape around the ports on the manifold before attaching hoses. Wrap tape around the Low/High port adaptors prior to screwing into the hoses. If NOT using the yellow hose, you MUST attach it to the back of the manifold tightly or else gas escapes through that yellow hose (obviously since it is the vacuum connection). Opening both of the manifold gauge handles at the same time becomes a simple pass-through from Hi to Low ports ... and thus an error in usage (and rather unsmart). Check YouTube videos for how professionals use this device. Otherwise, the unit is high quality for this price break.UPDATE 7/6/2023: Do NOT open either side valves on the manifold unless evacuating with yellow hose to a vacuum gas-recovery pump or using the yellow hose for charging. NEVER EVER open both gauges at the same time. Always close both only finger-tight (to not ruin the brass seats of the valve. If only trying to diagnose A/C, keep both valves on the manifold CLOSED.

My old gauges started leaking through the gauge faces so I replaced them with these. They work fine so far. All the needed adapters for R134A and can taps
