Can this gauge set be used with R-22 refrigerant?

I only used it with R134. Mastercool site might give you the specs on what you are looking for.

It cannot be used with r22 refrigerant. R134a only. Different gauge sets foreach refrigerant.

No. It's just the valve asm. A gauge may be bought separately. I transfered mine from my faulty valve.

No. This manifold gauge does not have R410 on its dials therefore it will not work.

No! This is a switching valve only! For the use of two fuel tank system. It doesn't have any effect on gauge, the tank sending unit controls the gauge readings. Gauge or sending unit needs more testing.

You can use it since it has an R-22 scale on it. But, if you are not sure whether or not it is a heat pump, I would suggest seeking professional help. If it is a heat pump, you are going to have to buy the adapter for the end of the hoses as these do not come with them.

I don't know why you would require certification but these gauges are not NIST certified. You can calibrate them, though using a dead weight tester and the adjustment screw in the face of the gauge.

The R-134a charging & measuring kit cannot be used for filling, assemble hose of the set is wrong in size, it is for R-12 so that it cannot fit with R-134a refigerant can. The product is wrongly assemabled.

Hi Edward, Yes, you can still use the gauge. You will need a two stage regulator that has a POL inlet connection. Your gauge would hook inline between your tank and then the regulator.

Yes, any carburetor setup that uses vacuum to synchronize the various carburetors on an engine can be adjusted using this gauge set.

As long as it's 23 guage it should work just fine. I use Central Pneumatic pins from Harbor Freight Tools, they are much less expensive and work just fine.

For r22 tanks, you need the one with the 3 gauges and at least 2 connectors to connect to both ports on your condenser and measure it properly. Unless you mean cans not tanks, like disposable loaded cans that need to be punctured by a tap and empty into the system, then yes this is a tap. That knob thingy on the end pokes a hole in the can to release its contents.

You may as well order an R-134 gauge set through Harbor Freight. Comes in a nice box and has the correct pressures on the gauge. 49 dollars and I've used my set a few times already with great results. My R-12 gauge set was almost 30 years old. Well made, but 20 more dollars gets you the real deal.

U can use these manifolds for any hvac system. The gauges are what u will need to watch. Gauges depend on what type of refrigerant you are using. Exp. if u are using 134a for a car u need 134a gauges plus the car adaptors for hoses. If u are using the manifold for 410 or r22 u will need gauges for 410 or R22

I had the same issue at first. I bought a manifold set off of amazon that was sold as an FJC but it turned out to be a cheap knock off. The hoses were all for R-12 not R-134. The quick connects for the high and low pressure side were 12 to 134 adapters and the only can tap that would fit the yellow line was an old R-12. I sent the cheap gauge set back and purchased an Interdyne AC Pro set and it works perfect.

Don't know about r22. It let me adapt my automotive a/c gauge fill hose from r12 to134a. Hope this helps

the gauge is labeled for r-22 r-12 and r-502. it wont hook up to an automotive 134a system with out adapter. not sure about r-410. the replacement for r-22 what type of system are you looking to service???
