That sounds very weird, as all fill nipples are a standard size.
Is there a paintball shop/store near you that stock's fill nipples/attachments? I would suggest taking the fill station along and asking the store to check it over. But honestly, the only fill nipples I know that were a different size were the Govnair system from around 1999/2000 era. The last time I used this set up was with my Custom Products regulator which was fitted to a UK spec Evil bottle, and even then the fill nipple fitted fine. Please let me know how you get on.
