JIFETOR 3 Way AC Manifold Gauge Set, HVAC Diagnostic Refrigerant Charging Tool for Auto Household R134A R404A R410A Refrigerant, 5FT Hose Adjustable Quick Coupler Can Tap R410A Adapter (Blue Manifold)

I like that you can read r22 r134a and 410 freon types. That is a big plus for me.The price was great. They appear to be well-made.

Worked well. Good quality, no leaks, just make sure all the screws are tight. I’m glad I got one with the air release valve.

Great product for value, doesn't include some useful adapters for 30lb tank for r134a great for use with individual cans. Would recommend 👌 but I needed for professional use. And adapters not included.

My AC unit needs a special tool to open the valve and this gauge kit comes with it! It makes the recharging process very easy!

Great product! Exactly what I was needing.

Great Price and I really wanted this product to work but the original and replacement order both leaked, tested against an Auto Parts Store ( O'rielys ) Rental. Very disappointing. The Home DIYer would never know to test this vital component. So be aware, you must put a vacuum on these manifolds or you will introduce air/moisture into your AC system.

Yes, yes it did. And I returned the product. Look, you know what this is and why you need it. OK - had it hooked up to the car and the compressor. Vacuum pulled, gauges off, held -30inHg for 60min. All good. Time to add the R134a. Here's where it ends. The adapter that fits on the refrigerant can is a side-clamp on type. Somewhat ancient by current standards, but ti also means you can't use the self sealing cans. you need the old pierce once - use it all - and let flow in to the air - cans. Then you screw in to the side-clamp the valve with can piercing pin. Guess what? Like other reviewers, this pin is NOT ON CENTER. So, the can doesn't discharge well/at all. OK then, try another can? Well, now you've wasted 2 cans to the air. Alright, so go to the local auto parts place and BUY a real brass screw on can valve/piercer with enviro-friendly self sealing cans. Check. Then come home. Realize the *&^%$#@ gauge set is a different size/thread yellow fill hose to the can adapter. Gee, I read that too....go back to auto parts store. Get the 'free rental' of their gauge set. It fits. Finish refilling ac on car. While doing this, take this set of Jifetor gauges and wipe them down, and gently place them back in to the shipping container, and send them back to Amazon.Better yet - don't even bother buying them. Go do a 'free rental' at the auto parts store and save yourself the hassles. YMMV.

Had trouble connecting low side and high side connections. Discovered BOTH were missing ball bearings that hold them on the shrader valves! Returned and got a new set that worked as should. This had to be a returned item, that got resent without replacing them.???? Looks like these connectors are poorly made. They sell separate connection replacements if needed later & your cheap ones break and your return time has expired. They don't look like they will last very long.

Only used once but job incomplete. Seems OK
