Household Supplies Refrigeration Tools | Gas Charging Tools | RCoupler for 1/4 and 3/16 Pumping and Flushing for Refrigerator

coupler is good for the price and I liked the plastic handle which is easy to handle.

I suggest every technician don't buy this product it's can't handle 350 or 400 nitrogen pressure if it opens while you using this in this pressure there is 90/ chance you will lose your life because there is no lock system in this coupler there is only rubber bush inside the coupler if the rubber bush is started grabbing it will be open you will hear that sound like boom blasting then customer. will blame on you

Coupler is good but washer inside coupler is not good very cheap material,there should be some spare washers given with this coupler
