Tonight when I went to fill my tank my compressor would only go to 580 psi. After looking it over I saw this green oring seal blown out of the filter body and leaking air. .

Do these two bodies just unscrew. Because if they do they are extremely tight. I figured this would be an easy fix but maybe not. I will contact hatsan on monday but for now I would like to get it going. It is under warranty but I do not want to send it back for something like this.

Any help is appreciated.

It seems that you have clamped the right side on a vise. May be you can try using two strap wrenches on the other side ?

O ring being squeezed out like this is abnormal. The photo is showing a significant gap at the joint . I bet it's already there when the compressor came. It's likely due to part of the O ring not fully rested into the seat . I have seen that happening on my gold filter when I tighten the end cap. Checking for this before tightening should prevent the reoccurence of the problem.

Hi Bigragu,

There wasn't any sort of lube present on the orings as you can tell from the pic. I also believe it was cut when it was installed at the factory. However, after all that it still wasn't building pressure. I did not look for the leak with soapy water before I tore it down as I just ASSUMED that was the problem area since the oring was sticking out.. Well I found the fitting on top of the filter is leaking and after several attempts to get it to seal I just gave up. The ferrule is distorted and has a ring in it as it looks like the line was a little crooked when it was originally tightened down. I contacted Hatsan this morning and am waiting for a reply. I would like to get both new fittings and a line with ferrule, plus I want to get more orings and filters for future use.

Funny thing is this worked fine last week and now it just goes to 580 psi before and after I tore it apart.

Randy, I’m not there so I don’t know how distorted that ferrule/fitting is, but try this, and when you do get the new parts from Hatsan, do the same:

connect the fittings onto the filter first(a tad loose just to allow swivel movement) before you bolt down the filter canister, then tighten down the fittings after.

These hard lines are like brake line fittings on cars, and they have to be installed perfectly with no tilt whatsoever on the hard line as it connects. It’s the nature of the beast with pre bent lines. Might be less than 90 degrees on one line and the next may be a tad over.

Thanks for the tips Bigragu.

I filled out the form to Hatsan and also called but still waiting on a reply. I work in the farm equipment industry so these type of things are all familar to me. I am pretty sure this line was tightened down crooked at time of assembly and after enough vibration it decided to start leaking. I wish I would have done the leak test before I took the filter apart but after seeing the oring hanging out I just figured that was the issue. hopefully Hatsan will take care of me. I really like this compressor.

Thought I would follow up and let you all know my compressor is up and running better than ever.

The last time I used this compressor I filled my buddy's 88cf tank from 3500-4400 and it took 23 mins. I should have suspected something was going wrong then but didn't pay attention that it took ten minutes longer than usual. The next time it would only go to 575 psi. I saw the green oring sticking out of the filter and just figured that was the problem. Well it wasn't. After rebuilding the filter I had a line leaking. Hatsan sent me a new line, filter and orings. After that it would only go to 875 psi so started checking everything over and really couldn't pinpoint the issue . Hatsan told me it was probably in the low pressure side so I took the head off. Everything looked good so I put it back together.

I then took the hp head off and found a bad oring around the base of the hp cyl tube. Replaced it and put it all back together. Not sure that was the pressure problem but it needed replaced anyway.

After putting it all back together I started the compressor and ran it up to 4350 and blew my circuit breaker in my garage again. I already replaced the receptacle and breaker so I was getting a little pissed by this point. But at least it was building pressure now. After a couple more tries the compressor wouldn't even come on anymore. So another email to Hatsan and they said it was probably the switch. Got the new switch in and the compressor came on and ran great going to 4400. Also didn't blow my cb anymore so I'm thinking the switch was my original electrical issue all along.

Fingers are crossed and hoping it will keep running a long time.

Oh and it filled my tank tonight from 3500 to 4400 in 13 mins and the temp only got to 162. 

So anyway I just wanted to pass this along and let everyone know that I got it fixed and Hatsan did a good job of communicating and supplying needed parts at no charge. It is under warranty and I really didn't want to send it back so they let me fix it which I didn't mind doing as I learned a little more about my compressor.

I'm glad you finally got it sorted. It's interesting that you say that it only got to 162, I assume you mean Farenheight, that is about 72 Celsius. A lot of people on this forum start having kittens if their YH pumps go higher than 60. It puts things into perspective when things are expressed on the scale that most of the readership understand.
