Tank Checker Bleed question !

[fireted]

DOes anyone know where I can find a schematic or service guide for the IST brand of twist bleeders that come on some of the newer tank checkers/ fill whips !
IST has not returned my phone calls nor email, and my Local dive shop is useless when it comes to service and parts.

Do you have a link for the tank checker you are talking about? I would give you some advice but I do not know if the design is like the ones I am used to.

This is the closest product I could find with a picture of the turn to bleed fitting.

Here's a picture of what I think you mean:

If it is that kind then your problem is either the seat (the plastic bit inside the knurled screw) is shot, or the orifice it sits against is not so good. You can try using an orifice polisher (basically a slightly more abrasive eraser) to clean up the orifice. If it is the seat (the plastic bit) you can make a quick and dirty repair by shaving off the layer of it with an exacto knife.

If it is that kind of bleed valve, any dive shop that does fills is able to order them from Global (which I cannot find through Google right now but I was at their website some time in the last few days). But they (Global) only sell to shops.

It seems that paintball supply store will have them too because they use fill whips.

I'll bet this place can get you some.

Exactly what on a transfill whip needs service much less a service guide. What is the problem.

You seem to have the new style, as manufacturered by Ocean Divers and possibly other Taiwan suppliers, where there is a knurled collar that rotates around the body of the adaptor fitting (as opposed to the old-style little screw with a nylon seat on the end that screws into the fill adaptor body).

We haven't had one apart yet, so I can offer no advice, but a lot of people seem to be selling them now, including some of the more customer-friendly suppliers like Salvo, NESS and TDL as well as Scuba Toys, so you might try contacting any of them see if they have any advice on how to service them, or if parts are available.
