When you buy stuff from ebay you have to have some knoledge because ppl selling stuff there are often incompetent

That's the case here

If you have doubts you can always email the seller and ask for clarification/ ask him if he has something with 1/4" BSP threads and he can check if the thing he is selling has BSP threads


Normally these guys are motivated to sell their stuff so if you write something along the lines of:

'I want to buy it but I've never heard of 11.3mm Threads. Could you check if it has NPT or BSP threads? I guess other buyers have the same problem as I do - so if you check it and provide correct info you will sell more'
thanks poland :P Can you identify the 3-way in this photo http://www.spudfiles.com/forums/files/qev3wayv_691.jpg

a slide check is a 3 way valve :-D

but it's a manually operated valve not a solenoid valve... I'd say lower your pressure requirements to 300 psi and get a solenoid valve

That's what I meant by:

some real good deals on pneumatic parts on ebay but the thread sizes are so poorly defined!


These things started popping up a few months ago on eBay, there's a lot more cheap-oh pneumatic fittings than before. It's such a shame that the thread sizes are presented in such a perverse manner. As I said I purchased a couple of quick couplings and they're very decent.
