do you mean filling with the EZ?
I use mine at high pressure tank fills and it seems to do alright. Though sometimes I do have to thumb the trigger to get it to release lately, so it might need internal attention from use.
Look for sharp edges that may be cutting the o-ring as it's moving during use. An o-ring that is in contact with a sharp corner edge will slowly slice and extrude it's way out of the gap as a thin layer. Also, try ptfe silicone lube on those moving parts as @bigHUN does. He's got a great procedure threre, as dynamic o-rings should be lubed to prevent wear and failure.
Exactly how many more gun fills to you get using the EZfill ? 1 , 2 , 3, 1/2 ,1/4 ? Although i could see this devise IF you only had a short time to shoot (maybe paying at a range ) or at home only have little time to shoot due to work / family .Ed (EPG) got me interested in this lil’ do dad. I really like it.
If you are at the range, or at the bench in your backyard and you fill from an air tank several times during your shooting session, take a look at this EzAy Fill Trigger from Edgun. $ 150, not cheap but worth it to me anyway.
While this is not an endorsement, I saw this on a recent AEAC review and Steve demo’d the easy way to fill your PCP air guns without removing or bleeding your fill wip from the gun each time you fill and remove the hose. A side benefit is that you save air, especially if you fill or top off 6, 8, 10 times or more during your session.
Here’s one example. I brought my RAW TM1000x .177 to the range this past week. My GW was approximately at 3600 psi when I started and is currently at around 3300 psi. But, I probably filled it from 150 BAR to 220 BAR about six times. I honestly don’t know how much air it can save, but it appeared to save quite a bit. I only bled the GW tank valve one time, when I was finished. You can leave the Trigger in your gun or remove it, based on your preference. I tried both ways.
I like the idea of using the red EzAy fill trigger vs. loosening the yoke on my Great White. Why? Because it’s simple, and I can fill slow or fast by controlling the EzAy lever which is spring attached. I use the GW tank pressure gauge to stop when I am at max fill pressure on a particular PCP. I also avoid bending over every time I’m behind the bench to fill the gun by reaching for the Yoke on the GW.
AoA and Utah Air have them in stock. Here is a link that describes the features below: There are a few YouTubes that also demo the product.
Your brass piston likely has cracked or missing sealing rings or the metal reed flapper valve is needing cleaned or replaced because it isn't sealing. It's not too hard to replace the whole YH piston kit assembly in them.
In the beginning I was replacing the brass second stage pistons only (I have couple spares now all time), but soon realized what amount of work is done it is just faster to replace the whole 1st+2nd stage pistons.
The answer to that question (how many more fills) will depend on the valve, the fill lines, and the tank size. It gets down to knowing the amount of air wasted with each avoided venting of the line. But there is one case I can tell you that makes a huge difference, and it is also one perfectly suited to the EaZy fill - using it on a tank with a regulated valve (or after an inline regulator). These valves "waste" a lot more air when vented, as internally they open up to full tank pressure, and then regulate down to desired line pressure - there is more internal volume in them to vent, and part of it is at higher pressure than in a non-regulated valve.
Yes, my time to shoot is valuable and varies greatly due to weather and schedules of the family. Not retired. The EZ is a time saver in my case......when it's working correctly.
I can see this investment would be great in your case . Time limited to shoot . "Squeezing in 30 minutes whenever you can " type thing .
