Help with Grex TS Tritium

I use my Grex TS Tritium airbrush off and on for the pass 2 years. I take good of the brush and clean it after every use. I last used it about 2 weeks ago and when I went to use to today I was getting only air and no paint. then I noticed that the needle was not moving as I pressed the trigger. So I began to strip it down and the needle would not come out the back of the airbrush. So I removed the nozzle and unscrewed the fluid nozzle but the fluid nozzle would not slide off the needle. I pulled the needle out the front of the brush. I soaked the needle in cleaner but it still will not come off. I am afraid if I do any more I will bend the needle.
Does any one out there have any good ideas. Need help!!!

you could try to gently heat the nozzle and not the needle...use a candle or some such....might work

I used to spray a dose of cleaner through my brush after each use, but after a while I got some strange side effects like bubbles in my paint cup, so now I strip the brush after each painting session...no problems since...

It's odd. I used it 2 weeks ago with no problems. I sprayed cleaner thru it. It looked fine but today it not. I do have a back up airbrush I use a Badger 200.
So I think I just may try a little heat on it. I did email Grex today on the problem so I will see what they say.

I got a reply from Grex and they said that the needle was pushed to far froward after cleaning and recommend just replace the needle and nozzle. Which is what I will do. Around $30.00 dollars. So everyone be careful out there when cleaning our airbrush

Also check the manufacture' instructions with regard to lubrication. Internal mix brushes and not intended to be stripped now and cleaned with normal use. They are intended to be very lightly lubricated occassionally. If you are having to strip clean after each session, you are probably not adjusted to how thin a mixture an internal mix brush can use for good coverage. Moreover, if you strip clean then you have to relubricate. Of course this is general advise however confirm. Or discuss these points with the manufacturer before you begin again with the new parts would be my advice. Phil

Replacement nozzle and needle kit came today. It's a TS .3mm. I also bought a TS .2mm set and some Superlube for the needle. This is the first time I used a lube for the airbrush. It feels like a hand soap. All new parts are install and airbrush is now ready for a test run.

Thanks Phil, I did my test run and the airbrush is working fine. I am now back up and spraying. I used the airbrush lube for the first time will see how it works.

John in your case I would have tried to clean the needle and nozzle in an Ultrsonic bath.

Joerg R. I did use a Ultrsonic cleaner to try in loosen the needle from the nozzle. For over an hour with no luck. With new parts and I hope lesson learned brush is now working.

Send in your frozen needle and tip, I bet Grex will replace it for free... I have one as well but didn't think to lube it... I'll start doing that having read all this...

Hey Greg, I did talk to Grex about the nozzle and needle and they said that the nozzle and needle are wear parts and are not covered under the warranty

Oh! Good to know. BTW, what did the replacements run you ... if you don't mind sharing that?

Greg, I got the replacement nozzle and needle at Chicago Airbrush Supply which has parts and airbrushes for many types of airbrushes. I paid about $35.00 dollars for the kit.

This is a tip I've ever gotten from a fellow model Builder, when you cleaning your Airbrush and put this this back together always pull back your needle a bit from the nuzzle so that it is not dries up in the nuzzle because this is made from a light metal and with a little pressure you can distort this. I hope this will help you ;)
