no worries! thanks for all your help, I think i'll use tam's (robart?) one-way disconnects unless someone comes out of the woodwork with a festo 3mm. Couldn't find such a thing on their site or SMC's.
My next quest will be for a dual digital air pressure gauge like todd's but packaged much smaller! [img][/img]
The smallest digital pressure gauges I've seen & used, were sold for a while by CJM. CJM no longer has 'em, but Sandor (Digitech here on RCU) stocked them recently - you might want to have a look at those.
