Liquid Charging Adapters 1/4 Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12749
Jlab Export is a leading Liquid Charging Adapters 1/4 Manufacturer,and suppliers in India
A liquid charging adapter lets a refrigerant blend leave the cylinder as liquid yet enter the system as vapour. Fitted at the low-side port, it meters the liquid through a restriction so that it flashes to saturated vapour on the way in. This one is the 1/4 in size, for standard 1/4 in service ports.

Lab Exercises in Charging Blends
After evacuating an R-404A system, students set a cylinder of R-404A Refrigerant to deliver liquid and stand it on the Wireless Refrigerant Charging Scale. The adapter goes on the 1/4 in low-side port with the compressor running. Liquid is then fed in slowly until the scale shows the rated charge.
While charging, students watch the suction gauge on the Manifold Gauges For Refrigeration Systems. If the suction pressure climbs sharply, they close the valve a little and slow the feed. Teachers can use the exercise to explain why a blend changes its mix when charged as vapour.
Frequently Asked Questions
What if the only low-side port is on the compressor?
Take extra care there. Refrigerant entering a port on the compressor body goes straight into the shell, where liquid can wash oil off the bearings. Feed it through the adapter in short bursts, close the valve often and keep the suction pressure only a little above its normal running value.
Why not feed liquid straight into the low side?
Liquid entering the suction side can reach the compressor, which is built to pump vapour. Liquid does not compress and can damage the valves. The adapter meters the liquid so that it enters as saturated vapour.
Which size should I order?
This adapter is the 1/4 in size, for the standard 1/4 in service ports on most refrigeration systems. R-410A and R-32 units have 5/16 in ports and need the Liquid Charging Adapters 5/16.
Can it be used with single refrigerants such as R-134a?
Yes. It lets a single refrigerant be charged from liquid at a controlled rate, which is quicker than drawing vapour from a cylinder that keeps cooling down. For blends, it is the usual way to charge a running system.
