I am looking to build several bypass valves and fit them to my tools, can anyone suggest where to buy the required parts featured in this video?

hydramaster sell them no? or similar

All them parts are quite freely available from any hydrolics or compressed air stockist, the only difficulty will be tapping into the wand.

I would suggest using compressed Airfitting as they are cheaper and less bulky, but only rated upto about 600psi

You can do it easier than Robs example but fitting an inline 3 port valve and getting a hydrolics supplier to make you a small solution line with crimped elbows.

This will also make the bypass less prone to damage if you bash it or drop your wand.

This is an example of a 3 port valve but you will need to find a smaller one (which are available)

To be honest Mike 600 psi is plenty, i have located a welding shop who can weld the stainless steel pipe, just need to find fitting which are compact.

Can anyone confirm the type of thread used in carpet cleaning fittings?
Im not sure BSP is right, as i recall i tried to use a BSP 1/4 male to male nipple once an it was wrong.
Would the thread type be NPT?
