1. The Forum Rules have undergone some minor changes and updates.  Please take the time to read them; it will only take a couple of minutes of your time. By doing so, you lessen the chance of incurring the wrath of the moderation team or making yourself look foolish to other members.

    90% of users posting adverts in the Sales forums need to be reminded to read the rules as their posts are wrong.  This is unnecessarily time-consuming and will no longer happen - if your advert doesn't follow the Sales Rules it will be deleted and you'll have to start all over again.

Even if this is just your own personal opinion, RESPECT YOUR FELLOW MEMBERS.'

  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

  6. Postings on Politics, Religion & Controversial Off-Topic Material

    The majority of users do not want to read about these subjects and people have left the forum as a result of it – this is after all an 'Airgun' Forum. It’s all very well to say they don’t have to read it if they don't want to, but as most of us use the ‘New Posts’ button there is no easy way to avoid it.

    All AGF staff members are in favour of people being able to discuss what they want, but we have to draw the line somewhere if it is upsetting other users. We don’t want to read about these topics either.

    IMPORTANT- The discussion of politics and religion is no longer allowed anywhere on the forum (including the Adult section).  The only exception is if it's airgun related - they must be put in the Airgun Related Politics section..

    We will not tolerate bullying or personal attacks, racism or any other offensive 'isms'. we will remove these topics from the forum, we will not give you an area where you can abuse each other. We will not hesitate to ban offenders.

Has Anybody Ever Changed A Dive Bottle Charging Valve (reg Assembly) Before?

    Hello all, I just noticed my 3lt bottle (Dive) was getting low. So I thought I would fill her up (to 300Bar) using my Omega Supercharger. All was going well bust I noticed it was taking ages (far longer than normal). Checked thing over and noticed my bottle was leaking!. It was leaking where the whole valve assembly screw's into the bottle. Looking closely I noticed a small crack running up the left side of the seam from casting. See pic's below:

    IMG_0781.JPG IMG_0782.JPG


    Have not a clue how this has happened? Maybe just a fault in casting?. The bottle is not a year old (loads of test left). Was wondering if anyone has changed one of these before? and will it require a test again if I change it. If poss I would like to replace it, and with a better one..

    I would rather do it myself if possible rather than send it off somewhere, It dont look much of a job, I think they are tightened to about 50 nm, so should come out easy enough..

    The valve assembly it has now is made by APEKS, was wondering if anyone could recommend any particular one to replace it with? It's a M25x2 size thread. I have seen one here for sale:

    https://www.bestfittings.co.uk/shop...-accessories/mde-jubilee-gun-charging-valves/

    Also I was thinking of getting a bare unit and fitting my gauge from the goosed APEKS assembly, I was wondering if they are all the same thread?. I could buy the full assembly but not sure I need it..

    If anyone has any advice, it would be much appreciated..

    Baz..

    Yes the Jubilee is the best on the market, specifically designed for guns not diving.

    Screw out screw in, easy!

    Have you contacted Apeks? I've always found their gear to be quite good & hopefully they will stand by this & send you a new one.

    I'm glad it was only a slow leak.

    Are you sure that is a crack and not a casting mark? Apexs stuff is normally good quality, I would hope the bottle supplier would sort you out

    I very much doubt that's a crack - probably just the edge of the casting / forging flash.

    Have you put some oil around the area to see where the air is actually escaping? Pound to a pinch of sh t it's coming from between the bottle and valve - is it a Hydrotech cylinder by any chance? I've seen quite a few newish examples with failed O-rings in this area.

    If it's less than a year old why are you looking to strip it yourself? For all the usual reasons you'd be far better taking it back to where you got it from and letting them sort it out. If it turns out to be something serious and you do it yourself you've got zero comeback and a worthless bottle..

    If you do it yourself make sure it is completely empty , also how will you know it is fixed until it's filled , I would take it back and get it sorted tbh

    Thanks for the reply's guys, it is in fact a hydrotech cylinder and as Cloverleaf stated turned out to be a faulty o-ring (between bottle and valve). Replaced it myself (easy job), filled it up and jobs a good one. :thumb:
