It migth also be usefull if anyone has links to (pneumatics) fittings suppliers. In the UK I often suggest:
http://www.airlines-pneumatics.com/w...duct-index.asp
https://secure.thorite.co.uk/index.html
http://www.ihp.co.uk/store/
as well as the big components suppliers
http://www.rswww.com
http://www.farnell.com/
But I've never found an suppliers accross the water when folks ask for parts links in the US or Canada.
