I have received numerous complaints from my shooting buddies for this. I have a Omega 75 cu tank with their standard valving when I/we go to release the pressure from the push button release valve most of them have to use two hands to depress it. The reason we are using my cylinder more is I'm the only one with a compressor. I let them save their bottles for their personal use.

One of the gentleman even ran home and got his Omega tank same as mine. His released with the slightest press. Not the 50 ft/pounds of torque used on mine.

My question is there an adjustment I can make? It's not really user friendly.

Thanks in advance

I have the same issue so, you are not alone. 

Take the retaining clip off and remove the bleeder pin. You may have to twist the gauge out of the way in order to do this. Then, add a little divers grease to the O-rings. See if that helps. When you remove the retaining clip, have a strong magnet nearby and a very clean floor!! Since you're in there, you might replace the O-rings as well or, get some headed your way. This whole process should only take about 5 min the first time. 

I'm not going to tell you to alter your OEM equipment and void any warranty or tell you to do anything that might cause you to have to buy replacement parts... But, I altered my spring with a quick "snip". 

Happy Shooting!

Tominco's tip is very helpful. I'd like to add that the retaining clip is extremely small and can be overlooked as I did until Tom told me where to look. Push the bleed button down and the small clip is on the bottom of the shaft. The shaft protrudes from of the opposite side of the valve body. It is so small it is easy to overlook. Now I understand why a magnet and a clean floor is required. This thing could pop off and disappear if you're not careful.

Regarding the o-ring size, everyone working with PCPs, tanks, and o-rings should own a digital caliper. Harbor Freight sells them for less than $15. It is invaluable for determining o-ring sizes without searching for online schematics or waiting for others to respond to sizing requests. Marco Rubber has a comprehensive online size chart that can be used to to find the correct replacement size for any o-ring. Measure the thickness, inside, and outside diameters. Most o-rings are either metric or USA standard sizes. It is super quick to measure and find your o-ring using the chart without having to depend on a reply or searching for a schematic. Europeans primarily use metric o-rings, USA manufacturers use the USA standard sizes.

Gentleman,

Thank you for your responses. Very helpful. 

I'll look over Marco Rubber's site. I can see I'm going to need a stock of O-rings at some point. Funny thing about caliper's, I truly believe I'm the only person in a two block radius with a set. I'm quite popular on Saturday mornings.

The repair went smoothly. I basically polished both ends of the spring and lubed the o-rings. It reduced the release to a user friendly amount of pressure.

BUT, now my dead head is leaking. Is this common?

Thanks again,

Dave

Dave,

One issue has nothing to do with the other. My thought is that the o-ring inside your female foster quick connect is not sealing properly. I use a 90 durometer 009 o-rings as replacements on quick connects but some guys use 70 durometer 010 size o-rings. These o-rings are hard to see inside of the quick connect but it is an easy replacement with a pointed pick or similar tool. It is highly unlikely that the dead head is defective. Check the dead head for burrs on the tip but I doubt it. I use 90 durometer replacement o-rings in quick connects because they are more durable long term than 70 durometer, and are just as easy to install in a quick connect. Sometimes a 90 durometero o-ring can be a PITA to install when stretched, like over a pelltet probe hump.
