💪 3-Stage Stainless Steel High Pressure Hand Pump for PCP Air Gun, 4500psi, Ball, Tire, Boat Filling - Includes Stirrup Pump (Silicone Oil NOT Included) Review

Junk, pump does not work. I'm only giving a review because I keep getting calls asking me to write. Hold cash and go. Save on higher quality and talk to someone who knows what you need.

The instructions suck, but I figured it out. I've had it for a few months now and it's still working. You really don't want to use this thing on a 2000+ psi gun. If you need to stretch it to 3000, you need to pause and let it cool. If you have the steadfastness or Diana Storm Rider/Bandit pushes the limits. If you have a glove or Beyond fugetaboutit! Go to the damn gym.

I fill the air gun cylinder up to 300 bar and check with a separate manometer. We agreed simply, but without much instruction. No leaks, cheap. It works. I'm really glad I didn't spend a fortune on something else. Make sure you have an adapter for what you are filling. Supplied with quick attachment. The only thing I don't like is that it doesn't hold up well on its own, but that doesn't matter. I hang it on the wall.

I bought this to use on the Umarex Gauntlet. I borrowed a Benjamin pump from a friend until this arrived. I've had Yosoo for about a month now and use it quite often. I find it easier to use, just requires less effort. I'm not saying it's easy, just easier. I took the pump apart to make sure it was lubricated and didn't have any burrs or sharp edges on it. To my surprise, all the details were well finished and the edges were beveled. As a result, I did nothing, I just lubricated the shafts with

I bought this to replace my aging Benjamin hand pump. I have a couple of PCP airguns and my Benji has been in the teeth for a long time (doesn't help, I'll refill my PP700 a dozen times in one shot) and I figured I needed a backup pump. This pump is perfect. It features a water jacket to cool the 3-speed pump. None of my PCP air pistols pump more than 200 bar, so that's more than enough. It also turns out to have a larger displacement than the Benjamin pump. What used to require 96 pumps now…

It's hard to tell if these Chinese made air pumps are inferior copies of more expensive and possibly higher quality air pumps sold under the Benjamin, Gamo, Air Venturi etc brands, or if you're just paying for a sticker with the latter . Yes, the instructions are poor. You'd think the marketing department could give an English-speaking employee an extra $100 to write logical and grammatically correct directions. Damn! "HIVBEE" documentation and instructions state "O-rings and other…

Reviewers here talk about buying silicone oil to lubricate the pump, but "silicone oil not included" in this list is silicone oil that should fill the gauge! It's a blatant omission that they don't state that the missing silicone oil is for the gauge. So you get a dry meter that you need to fill with silicone oil that you need to buy. Silicone oil really isn't that cheap. You can replace the silicone oil with glycerin, the only difference is the operating temperature. Silicone oil is the best…

Bought LP2 for some gun parts and Magnum Airpower LLC high performance silicone for the pump. The quick connector is 8mm long, so please buy a 1/8 inch BSPP male, female quick connector to install the PCP sensor if needed. (Hatsan needed that) teflon tape and some solid ALL connections. Used about 10 times to date to pump the flash from 100 to 200 bar (2000 to 3000 psi). I didn't tear it apart but a wrench is included and some o-rings but no instructions. Chances are generic videos or well…

The pump had difficulty starting. The instructions were, well, a picture and a lot of guesswork. As far as how the pump works, it's not smooth sailing. I used silicone oil and it hangs in the middle when I move up. It got very hot after pumping, which is what I expected. (A word of warning if you're carrying and reaching for shotguns. It hurts.) I switched it to silicone high-temp grease. it hung less and cooled faster. The exhaust valve now comes out very easily and can be lost if you are not…
