    A Reg Service Racket in Australia

    So I just had a conversation with a guy from Australia who is BUYING A SHOP, but Scubapro won't let him attend a manufacturer's certification class until he's serviced 100 regulators. Pretty interesting, compared to the US of A, where 1/3 of the participants at every Level I Scubapro seminar...

    MK10 Rebuilding Mods and Best Practices

    The recommendation to remove the polished surface for the piston shaft oring is a crude solution to an old problem. If you drive hard around a curve on a smooth asphalt road, you may roll your car. If you do the same thing on a cobblestone street, you'll just skid. By decreasing the surface...

    MK10 Rebuilding Mods and Best Practices

    Having a SPEC Boot, DIY or original, requires a groove that allows the boot to serve as a reservoir for piston and lube movement. Though it's been done, a boot for the Mk25 or Mk18 has no accompanying groove, and hence no reservoir. Though it's beyond the scope of this thread, I would...

    Question What is the most effective way to clean off old Christo Lube from a environmentally sealed 1st-stage?

    The recommendation of base oil to remove Christolube is too vague to be of use. https://www.machinerylubrication.com/Read/29113/base-oil-groups Many of these are not oxygen compatible at tank pressure and will require significant removal cleaning in and of themselves. In industry, both hot...

    Why Surface with 500 PSI?

    Almost two years now since the last post, but I still get pings as folks react to posts in this thread. Good on ya! That means that folks were still scrolling down to page 27 in the Basic Forum to find good discussions on important topics. I think the concepts discussed in this thread are...

    How to fix a TFX 2nd-stage that keeps leaking slowly whenever it is purged?

    An incredible design, indeed! Water usually enters a reg at the fluttering upper edge of the exhalation valve. Where a standard reg guides those droplets right down your throat, the TFX allows them to accumulate in the bottom of the reg where they are blown out with the next breath. It is...

    How to fix a TFX 2nd-stage that keeps leaking slowly whenever it is purged?

    I mentioned this issue in an email to the Chief Technician Trainer at Huish. We'll see if he has any thoughts.

    How to fix a TFX 2nd-stage that keeps leaking slowly whenever it is purged?

    As I reread your post, I was struck by the connection to purging. Can you just breathe from a pressurized reg with no onset of freeflow? The valve opens and closes normally? I think that's what you told us... If it's just related to purging, when Venturi takes over, that's the time the lever...

    How to fix a TFX 2nd-stage that keeps leaking slowly whenever it is purged?

    There are two possibilities. We saw exactly this problem with the Scubapro D420 when it was first released. Your comment from the manual about lever slack is the key, but it's not intuitive since the valves are so different from end balanced barrels. If (for whatever reason) the lever doesn't...

    Scubapro MK7 question

    Hi, Mariano! I'd be happy to send you a selection of orings, one of which should work. Postage to Italy may be crazy, but if someone closer to you doesn't chime in, send me a DM with your address, and we'll make it work. If we can get a good postal rate, you can have the orings for free.

    The New Atomic TFX

    I just ordered 50ea. of the 13 o-rings in the TFX, in Nitrile (50 was the MOQ for most of them). EPDM wasn't available for several of the half-millimeter sizes, and IMO, Buna-N is a better seal anyway, since oxygen isn't a worry at second stage pressure. Three AS568 rings were 2 cents each...

    The New Atomic TFX

    Maybe there was just one lot of thin plastic diaphragm retainers. Or in the plastic press, there was just one of a bunch of rings that wasn't fully machined when they squirt in the resin. If it's 1/10 or 1/100, not too surprising that it was missed on testing. I'm just glad Huish is...

    The New Atomic TFX

    The service manual and schematics are complete. Manuals, spare parts and service kits are not being released until a technician completes a Huish service course, so I can't help you there. O-rings look to be a mix of AS568 and metric's, with no British Standard 1.6mm in there, as I once...
