  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.

  5. 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.

    I've been reading everywhere but can't find the relative size, everywhere says the quick probe sealing o rings are 5 x 1.5, they aren't big enough, one of the seals broke so I ordered some according to sized list and there alternatives. but they aren't big enough.

    From a parts diagram there are two part numbers
    2618A 5 x 1.5
    there is also another o ring marked as 2710
    but i can't find that correct size written down anywhere else

    Anybody else had the same issue, probably a very old quick fill probe, probably a different size seal used on them, bit stuck for the weekend, can't find small packs anywhere near me, so multi assortment for £!2-£15 or but a whole new probes seal.

    Anybody got any ideas :thumb:

    I had been speaking to blackmax earlier on in the week about the same gun, this is just a problem with a broken O ring, I'm out of air can't fill it up at the moment for the sake of a 5p O ring I don't know the size of, got abit of work to do on it but can't even have any air at the moment:facepalm::facepalm::facepalm::facepalm::facepalm:

    Thank you @sharpsman , my micrometer seemed to say somewhere around those figures but it's impossible to be totally accurate with soft rubber and metal jaws, it was definitely under 2mm and trying to measure soft rubber internally is even worse, I was trying to pick up a 5 x 2 pur 70 just as an emergency until I can order some, that would only work out .06 mm bigger so should work for a carefull fill just for now, I was going to go along the lines of a new Quick fit adapter to go with the set of "Best Fitting" kit I just got , so didn't really want to buy another screw on adapter, to fit it into a " best fittings" quick couplers set :thumb:

    I'll let people know when I do :D:D, when I didn't need "O" rings , i was just gathering up a kit, they came next day, because I needed them they're taking 3 days :smash:,but at least I should be able to get some air into it now , the new quick couple probe arrived today that fits the new best fittings kit I got last week (well I bl***y well hope it fits them):laff:

    You can see why I was frustrated, using the HW100tuning's exploded diagram, they are about the only ones who clearly mark out this "O" ring as a type A or B part no. 2710, virtually everywhere else just lists the 2618A , which is the 5 x 1.5 that didn't fit, got a bag of them now that do fit the new probe though. Picture here should show what I'm talking about

    No, I know they are not a tight fit in the tube when you push it in , but even with 2 of the new "O" rings it just slops about and slides out without the hint of wanting to stay in, the new probe only uses the 5 x 1.5 that pushes in lightly and fills it up a treat, the gun is pretty full at the moment but just trying by finger with the old one pretty much tells me it will leak, I've got to change a few fittings about even just to try it as they all go on via best fittings quick release now that kit arrived and I'm swapping everything over.

    My eyes aren't the best these days but to me, the slightly damaged one looks a little bigger, maybe just stretched , butb the section looks just that little bit bigger ??

    Just a quick update, I now think those are the correct size ?, I screwed on a best fittings adapter and cleaned the fitting so no hint of grease, put on 2 new "O" rings, tried it , once the pressure gets to equal the gun so filling can begin, it blows the top "O" ring off, so however badly they fit it gets to about 100 bar pressure wise , then it blows the top "O" with a sharp pop, the new fill probe doesn't sit in the cylinder extra tight with the smaller 5 x 1.5 "O" rings but will easily get to 200 bar without a whisper of a leak, so I think the best thing to do is treat the old one to a trip in the wheelie bin on Tueday :)

    We have oversized ones, many people prefer them. 5 X 1.6mm

    Bs008's are usually too thick for the groove width, which is 1.7mm generally

    Is this a standard set up HW100 with a standard cylinder? They look like A&M probe Orings for the A&M probe and Cylinder which is not exactly the same size as the W one.....?

    The experts again and the all o ring lists from the forums...

    Instead buy the full probe for a few quid, will fit and no headache.
    By the way a AGT fill probe works too.

    Im not 100% sure this even the correct fill adapter, it looks like the correct item, it's what came with it, I know no more than that. :shrug:

    @HW100Tuning

    Thanks for replying , I don't think your oversize will make much difference, not being rude the 5 x 1.5 didn't stop air at all, chances are your oversize seals adding a further 0.02 mm probably won't seal it either?? ,but looking at the picture, the one that fits with the little gaps either side is the BS008, the one on the end is the old now knackered which did fit but is well past it's sell by date, but clearly looks a good fit to the groove
    20190920_164016.jpg

    When on the end, the 4.57 x 1.78 simply blow right off the short end and a small part of the ring comes out the cylinder end caught between the fill probe and cylinder spout . I was watching your stuff on evilbay until you suddenly went on holiday then it looked for all puposes like you dissapeared off the face of the earth :D:D

    @The burpster

    Standard set up, you must be a bit of a mind reader though , I do have a A & M cylinder waiting in the wings, but that didn't come with a probe and it hasn't been fitted yet due to testing needs and constant removal of the cylinder after alterations :rolleyes::rolleyes:, spooky :)

    20190920_171106.jpg

    @Wewekokowe

    If you had read some of my other posts you would have seen I've been advised by the experts, I tried all the forum lists as to sizes for the probes , I have bought a brand new probe and stopped all the headaches :)

    20190920_170941.jpg

    All I simply wanted was a bag of cheap "O" rings (THAT FIT) just to make up a spare filling probe, how hard is that to try and achieve , bloody near on impossible :mad::mad:, with that particular probe, I ordered the new probe last Saturday, the moment I found out I couldn't buy an "O" ring the size I wanted locally on a Satuday morning. I'll spend more on "O" rings than I will buying another new fill probe , The 5 x 1.5 fit the new probe , so they aren't wasted, I simply bought 10 x BS008 as they were only going to be for that old fill probe, so that didn't break the bank :):).

    If I ever come across a 5 x 2 I'll give that a try, it boiled down to I simply lost 4 days work time on the rifle for the sake of a 5-10p "O" ring :smash::smash::smash:.
    Apart from that, the wheelie bin is still looming :laff:
