Torp,
They look like push-in fittings to me (similar to industrial pneumatics) rather than the Robart external barb type. If they are 4mm, which I think they are, I can "borrow" all the fittings off the shelf at work....
I've asked the question and am waiting for Eurokit's reply.
By the way, just found out the price from Ripmax in the UK - £199/pair (should be called Rip-off-max!!)
