Lichamp Liquid Vaporizer for HVAC R410A Refrigerant Vapor Charging Liquid Low Side Charger with 1/4 inch Fitings

Well built vaporizer for liquid to vapor charging of 410A. Does have a check valve - would not flow backwards. Install on suction line at manifold. Speeds up charging and protects compressor.

This appeared to perform as intended, vaporizing the R410a refrigerant while charging my ac unit. I had some difficulty getting a pressure reading when attached to my low side gauge port so I connected it directly to the refrigerant tank. As another reviewer commented liquid does appear in the gauge sight glass. However, upon bleeding the refrigerant line only fine vapor appeared to flow. Overall, I would recommend this product which made charging the system much faster without overloading the compressor.

Finally used this, does not flow. I ended up slow charging with vapor on the low side in the middle of the job. It was past the return window so it’s gonna become waste.

This device lets you change liquid to gas form for charging ac

To Taylor yenee with 10 years of experiences the device converted the liquid after a pass from your gages not before that's why you see liquid inside your gages hello!!!

It does keep the refrigerant in a liquid form instead of feeding gas into your system when charging. Which speeds up the charging process. Works with all gauges but I have used it with digital yellow jacket gauges.

The product appears to be of good quality and is what I want to attach to the vapor line side of by gauges. But out of the box, the plastic seat used to seal the connection is too long. This does not give you sufficient threads to attach to the gauge. It seems like it will be easy to modify this so it fits - but you would expect it to fit out of the box without requiring modification. Aside from that, I would recommend this product for its build quality.In the attached images, you can see the plastic seat that is too tall and where it is inserted in the expansion valve. If this were half the original height, it should work.

I bought the Yellow Jacket 42201 Series 41 Manifold and added this to it. Worked great and charged my ductless mini-split just fine. I would buy again.
