    Considering that the US still doesn't use the metric system, we're gonna be dealing with yoke for a while

    Vinegar is good. The brush has done no damage to my valves.

    Its not the standard for the country, but there is sure enough of it around. If I didn't have metric tools I'd be unemployable.

    I just think it's crappy manufacturing. I have both metric and imperial (hard to come by here and in UK) Allen Key sets in my dive box tool kit and I still find weird sizes I don't have a key for.

    It's a bug bear of mine, why can't inserts just be a standard size. 8mm or 5/16 suits me fine.

    @The Chairman - Last time I came across a seized insert (caused by over tightening not corrosion) my impact driver just rounded out the brass centre, so I had to fall back on old faithful - a hammer and chisel to beat it into submission. Fortunately only the once have I have an insert stuck that badly

    Do you have a picture of that? If the right tool is properly sized, seated and used correctly, rounding the hex should be almost impossible. I can't imagine the brief torque generated by a hand impact driver to do that, but the vibrations cause the corrosion to crumble away. I have even gotten cracked inserts out using one. I did resort to putting one well encrusted valve in an ultrasonic cleaner loaded with fresh vinegar. It came apart, but part of the inner thread had disappeared in the process. The valve was removed from service.

    Okay, I've ordered a pack of Viton 112 O-rings. Hopefully this should do the trick. Thank you all for your help!

    Well, the O-ring worked perfectly.
