Orion Motor Tech 4 Way AC Gauge Set for R410a R22 R134a Refrigerant, 4 Valve Automotive AC Manifold with 5ft Hoses, R410a Adapters, Can Tap

It works well, was able to fix a leak in my ac with this and a vacuum pump. It didn't come with the new style can adaptor though so make sure to buy that seperate. It only had the old puncture type adaptor.

Why did you pick this product vs others?:For the price and versatility it's a great buy.

Great kit.....worked like a charm....love having Low/High/Vacuum/Refridgerant hooked all up at once.....valves are of a decent quality.This gets four stars due to the super cheesy can tap they give you....had to use my old one. This POS never had a chance of sealing.Funny that OMT would have such a great manifold and such a crummy can tap.....

These gauges are excellent. Everything you need. The only thing that could be improved is the plastic case could be bigger. Hard to get the hoses back in just right to close it.

Works great! Having adaptors make changing task easy.

Worked ok for pumping lines down but I question how long the seals will last. Rubber bits coming off the seals after first use...The can adapter for adding refrigerant simply does not work propely, when screwed down all the way to the refrigerant can. The only way to get the refrigerant out of the can is to let it leak out of the connection. Basically you have to start unscrewing the refrigerant can from the adapter while the pin is depressed into the refrigerant can. If you're good you can get the perfect point where the refrigerant doesn't leak into the atmosphere and still comes out but it's a VERY narrow window. Tilting the refrigerant can from this point can cause a leak. Oddly, the pin doesn't have the be extended that far for this to work, which indicates that it's not sealing the pin to the can. I also tried two cans of r134a, same result. But if you screw the can all the way down, then depress the pin, NO refrigerant escapes the can. I mean NONE! Even after fully depressing the pin into the can, fully retracting the pin, then unscrewing the can, absolutely no pressure relief at all...make no sense at all. The little stand alone blue recharge hose works infinitely better but you can't vacuum the air from it...Of course it's too late for me to return it by the time I figured it out. Mostly used for diagnosis and pumping which it works ok for, gauge needle doesn't go all the way to -30in of mercury. I know on other gauges my vacuum will suck vacuum lines to -30in in well under 5 minutes. 45min later and this gauge reads just above -30. Based on the reviews and price I thought this was it but sadly, this is not it.

Low pressure side gauge arrived scratched. The storage case is too small for repeated use...You must wrangle the four hoses around the manifold valves to get the lid to close and then, the case is bulging. The refrigerant can tapper is not of good material quality....I don't trust it's grip because it has a sloppy cam. Beware of metal burrs on copper fitting when assembling hoses...got my fingers cut.

The gauge block is very hefty and I was surprised by its weight. If it drops it will surely ding the fender easily. The fittings are of decent quality along with the heavy hoses. Valve knobs all are metal open close smoothly. The only thing I did not like there was no resistance when turning at all and made me think sealing at the stem would leak but all seemed ok. The hose end valves were heavy metal having resistance of a tight seal on the stems. The hoses were flexible but solid, I could not squeeze the hose to flatten at all. The plastic case holds everything while it’s not assembled but it will not accommodate a fully assembled with hoses device where you have to disassemble to store in the case. Even if you remove the foam cutouts you still can’t store it assembled, not big deal to hang it assembled but it can collect dust but don’t count on storing it assembled in the case. Tested it and all seemed to work.
