    Aeron B96 CO2 Piercer Seals

    Where can I get some of these, magic9er has some on his website but I am not sure if he is still trading.

    What size are they? Tried some generic ones from the hardware place but they mashed up.

    Any favourite seals for this semi-auto? Probably the same as for the Tau 7 and similar ...

    Plain O-rings from the hardware store will just be nitrile seals that absorb CO² and swell up and get mashed.
    Polyurethane ones will be best being resistant to the CO² and to abrasion too...

    I've read that some Jonnys on here cut small sections of automotive fuel pipe to make piercer seals?

    Maybe those for the Tau 7 fit.
    The cap isnt exactly the same in depth, but it is in width.

    The same seal fits a lot of C02 pistols and a few rifles.

    Baz fixed me up with some polyurethane seals for a Tau 7 - worked a treat I had no joy with the seals that came with the pistol or the replacements that I bought from the UK distributor (they would bulge/distort/leak CO2)

    Have you tried a smear of vaseline round the seal,it works a treat on my B96.

    Yes I did try that after a previous recommendation (might of been yourself) but no joy. The sealing arrangement is a curios design, an o-ring fairly loosely within a groove, sliding inside a tapered tube.; it must be highly dependent on the sliding interference fit. The seal must be made before the C02 punchuresd otherwise it could blow out/distort the seal. The OEM seals are quite soft and easily get pushed out of shape, on mine it used to leak straight off, or after one shot.

    The polyurethane seals are much more robust and secure and worked perfectly in my Tau 7; maybe there is some variability in the internal tube diameter.

    That is a proper 'TOPS' heads-up, cheers.
