H&S Ultra problems

[Mr Bowcat]

Shouldn't be a problem Dave, if it was paint it would dry on the cap rather than build into a droplet. I get that with my H&S Evo when I'm blowing water or IPA through to clean, never had a droplet when using paints.

Could you post a photo of the AB and the nozzle end complete. thanks

Here you go John. Let me know if it's not what you wanted to see. My photography skills are limited, but if there's any other views you want, I'll give it a try.

Thanks Dave.
I was going to ask about the nozzel but when I went on line to look for that parts list I came across an old posting from you in 2016. Feb. Has this problem started again or did the seals that John got not work ?

Then they sent me the diagram from their website asking which parts I was missing - 123450 and 123471 which I cannot see anywhere on my A/B.

Dave, if it is the same as the H & S Infinity, 123450 is a set of 3 white PTFE rings, like short slices of tubing. They fit inside 123471, which is a brass threaded collar with a screwdriver slot. Tightening the screw pushes the PTFE seals into a taper, which should tighten them onto the needle.

The seals that John kindly got for me were for the air cap. They're not shown on the exploded diagram because H&S don't provide them for their Ultra model! I can't see how the A/B is supposed to work if there's not a proper seal between the air cap and the main body.

I've had a good look inside my A/B using a desk light with a magnifier. I know they're supposed to fit somewhere between the hole where the paint cup fits and the trigger mechanism, but I can't see any sign of either the seal or the retaining ring. Shouldn't I at least see the slot at the top of the retaining ring where it is screwed into place?

Dave.
Its seems that you've got a real problem, I'd be inclined to send the damn thing back to H&S and ask them to have a look. If they can repair or sort it well and good , but otherwise I'd carry on with your cheapo. Life's too short to worry and it's just not worth it.:smiling:

I thought of sending it back - then I thought "if they don't answer their emails......"

Dave, unscrew the back cover of the a/b, then remove the part with the needle chuck and spring in it (126603). Look down the a/b from the back and you should see the slot of the retaining ring. Is that where you're looking?

That's exactly where I've looked Pete. I still can't see the slot - but I found it using a small screwdriver. :smiling: Must be my poor eyesight. :sad:

Anyway, I've tightened it a little and can now feel a little resistance when I put the needle in. Hopefully that's sorted it. If not, I'll order a new seal from John.

Thanks everyone for your help.
