Iwata Eclipse Sticky trigger

Well, just as I new it would happen....
Just got all my stuff, and I think something is broken already. The trigger on my eclipse seems sticky. I have yet to run air to it because it appears that I need a few adapters. So... so far not a happy camper. See the attached link to my video. I tried putting some lube down in the trigger area....no luck.

 
Might need to remove the trigger and lube the pin that contacts the air valve.
 
If the o ring in the body is dry or gummy it will do this
 
Was the Eclipse new or used? If it's used, I'd say someone soaked the brush and swelled the o-ring on the air valve. Otherwise, they may have put some superlube on the valve, that stuff tends to gum up after a while.
 
Never had that one happen. Have had the seal in the qd male squish when tighten and block of air flow.
 
CRISIS FIXED... peep video...you wont believe what was causing the issue...

Looks like it's a small hole in the gasket of the male QD. Over tightening is probably crushing the rubber, expanding it inward and causing friction against the valve stem.
 
Glad you got it sorted. I thought I had a dodgy Iwata eclipse hp-cs too. Really had to pull back on the trigger for paint flow. I changed the paint and it works much better now. I was using a brand called 'Spraycraft Acrylic Liquid'. It's crappy!! Got my ' Createx Wicked Detail Primary Set' and seems to marry a lot better. I don 't have to work so hard on the trigger now. Anyways, happy ABing.
 
I have not ordered a quick disconnect yet, but will watch out for this when I get one. Glad you got it figured out!
 
I haven't had that one happen before! You learn something new everyday :) I notice that you seems to have ptfe tape or something on the thread of the gun? Is it leaking without it? I just screw my QD straight on and never have any issues.
 
My quick fit fitting doesn't have a flat washer like that, just an o ring so the pin can't hit the washer,also having just an o ring with also mean you won't need the Pfte/Teflon tape as just nipping up on the ring will seal it.

I just did that out of habit from working with air tools...don't even know if it would leak with out it or not...did want to take that chance
 
Also glad it got fixed. You could just trim the hole a bit bigger. On most of my couplings they also have the o-rings and there I've found that if you tighten them too much the o-ring actually tucks itself into the bottom of the airvalve. I also use teflon tape just out of habbit as well. But also as a precaution. I don't want cleaning fluids to dam up in the threads between the gun and the coupling as I never take it off when I clean.
 
You're probably not going to believe me Michael, but you've just helped me immensely. A couple of days ago I took off my mini water traps to put on the external Mac valves. Put the QD back on there and noticed the EXACT same thing happen on only one of the 3 brushes (all Iwata and Iwata parts) I left it for the night before I started doing something stupid, and was going to try and figure it out tonight - now I have a starting point - I'm betting that's the problem, I probably have got a little zealous tightening the Mac valve.. I'll let you know in an hour or so if it worked
 
Nope it didn't work so I'll tear it down today, possibly a bit of excess paint where it shouldn't be [emoji49]
 
Not to worry Michael. This brush has suffered in my hands, we've had several paint eruptions from the cup from a clogged nozzle and obviously not cleaned as well as it should have been.
The stickiness isn't noticeable when the air is connected, or when the factory spring is in it.
After I finished my paintpal I gave it a thorough clean (or so I thought), changed the air valve spring to a soft one and put an inline MAC valve in. That's when I noticed it was 'sticky' I did a check last night and yes the air valve seal is dirty (tissue with reducer told me so) so over the weekend I'll figure out how to get it out (gently) to clean it up.
After seeing your post I checked the brushes and yes the were probably both way too tight, so I've backed them off a bit:
If nothing else you've probably saved me some squashed seals [emoji3]
 
A little smear (and I mean minuscule) of lube on the air vale Piston had done the job for me but your info is firmly embedded into my head Michael
