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.

    'Behaviour

    Do not make inappropriate or offensive posts - including threats, harassment, swearing, prejudice, defamation, deliberate insults or name-calling, other negative remarks about this forum, its moderators and administrators or your fellow members. 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.

  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.

    How long is a piece of string? It depends whether you want an assorted set such as the Hilka one sold in Screwfix (cheaper on Ebay) or a smaller set such as the £2.20 one from Toolstation or whether you want to buy specific sizes in quantity. First you need to know the sizes you expect to need.

    Search 'O ring seal' on Ebay and prepare to spend a few hours browsing.

    If I know the specific size , I pop down to my local bearing/seal supplier and buy them by the hundred. ( Eg. the O ring seals in hosepipe fittings are £1.99 for 4 in my local garden centre and £3.80 + the dreaded per hundred in the bearing suppliers)

    I've been a pressure vessel engineer for most of my life and have used seals of all kinds

    Question...... Where do 'Approved sellers' get their O rings from?

    Answer ........ From the same manufacturers and Wholesalers as all other trades do.

    All seals are made to international standards and as long as you know the Material is correct, usually the standard is

    Try SealForce on the Bay https://www.ebay.co.uk/usr/sealforce53?_trksid=p2047675.l2559 :up:

    DON'T be tempted to buy the cheap kits from the likes of Aldi or Screwfix as they tend not to be of the right material (i.e. 70 shore Nitrile) and will not last very long

    Sadly that seller currently has no items for sale and only 1 feedback this month, they may have jumped ship :(

    This is the supplier I've used, they do specify material and hardness and a very comprehensive range of O ring sizes. Min quantities 10 off, sometimes 50 off. I've used a few of their O rings on piston head conversions (springers), oil and fuel caps on chainsaws blar, blar. That said I can't guarantee the products and you might find cheaper elsewhere.

    I'd be interested to see what others think of them and where you end up sourcing O rings.

    I sell seal kits for quite a few guns and buy from a UK maker to industry standards
    seals supply uk on evilbay are good, most of the other suppliers on evilbay are dearer but many think they're buying better rings because they cost more not always the case
    the generic kits are fine but you can buy from polymax or barnwell services if un sure

    I have 4x1.5 in nbr 70 but I haven't 2x1 or 9x1.5 in nbr 90- I have 9x1.5 in nbr70
    I can order them but I won't be ordering for a week or so and you'll pay 2 lots of carriage
    try the evilbay company I mentioned
    if they don't list the 90 grade just message them and they'll sort you out I'm sure they're a very good seller

    You'll struggle getting 90 shore/pur o-rings cheap in small quantities. Search for Viton or polyurethane.

    That's who I was using, they've been going for years and supply to the trade, however, they seem to have disappeared.

    90 grade are as easy as getting Viton hnbr epdm I find but getting poly now that is harder and they cost the earth
    last poly ones I got I had to have them made by one my suppliers who makes them from rod on a cnc
    I think I prefer the cast poly ones though but just can't always get them at a viable price
