Yes. The easiest is a clamp on style that bolts straight to your low pressure pipe/tube and pierces the line.
The low pressure charging valve is on the accumulator........
It is either on or near the recievr dryer in the right rear of the engine compartment. To corrrectly add freon, you need gauges and a refrigerant recovery system
You have to add a valve to the dehumidifier in order to put Freon in a GE dehumidifier. The reason you have to add the valve is because dehumidifiers uses a sealed unit.
You can add a tapping valve(which almost always leak after a long time) or braze in a schrader valve.
There is one valve that is used to add refrigrant. But you had better not add Freon. Freon is R12 and your vehicle's A/C system does not have Freon (R12) as a refrigrant. More than likely it uses R134a.
where is low pressure valve on a 2005 ford 500? i am trying to add freon
The schrader valve on the low pressure side of the system.
RV refrigerators do not use freon but rather ammonia. The ammonia is in a sealed unit called the cooling unit and you cannot add ammonia to this unit. If it goes bad it has to be replaced.
When you open the hood, on the left side there is a skinny pipe and you will see a valve with a green cap. This is where you put in the freon. When you buy the frion, it should come with a hose that just pushes on to the valve and shoots the freon into the pipe.
Connect a freon gauge and tank to the low side ac port of the 97 DeVille. With the engine running and the ac on high, open the freon valve. Shut the valve when the ac gauge reads full.
Through the schrader valve on the low pressure side.
Where is the intake valve / connector to add fron to my 2005 Kia Optima, with a 2.7l ^-cyclinder?
