1.5-Gallon Stainless Steel Hand Pump Sprayer for Garden, Lawn & Cleaning | Durable Outdoor & Indoor Spray Bottle for Pesticides, Fertilizers & Watering

I bought the Longray SP6A pressure sprayer. This sprayer is all metal except the hose. It appears to be a robust and very well made unit that has every feature you could want. An easily accessed and cleaned filter in the spray valve to minimize debris from reaching the nozzle, a pressure release valve, a pressure gauge, a shraeder valve to permit pressurizing with a separate bicycle pump, if you prefer a bike pumps longer stroke to the necessarily shorter stroke of the built in pump. It comes well packaged in a sturdy box. It is very easy to assemble the hose to the pressure canister and the spray valve and wand. No tools required. Mine came missing one O ring in one end of the hose. I found one in the bag of spare O rings and gaskets that came with unit and installed the spare. That process is worth a mention here. I called Longray when I detected a loss of pressure in my initial test of the unit. At Longray, a live person answers their phone and provides immediate and knowledgeable support. He assisted me in testing and diagnosing the cause, which took all of about 5 minutes, we found the missing O ring in the hose connection and I was immediately able to replace it from the spares included with the unit. A subsequent long pressure test of the unit, 3/4 full of water, Still ongoing, at 52 PSI,(the top of the green zone on the pressure gauge) has shown no sign of any pressure loss, after over half an hour. If you buy this product, Longrays support of their products, and the quality of the experience of dealing with a company that actually cares what their customers think of them, could prove to be worth as much to you as the utility of the unit itself. I am pretty sure I will have and use this product for a very long time, provided no one runs over it with a truck.
