whats this

[Simon]

Works like some sort of line lock, but using plastic hoses (no not much use for brakes)
What would it be for?

Is that aircraft or race car? I would guess it has something to do with safety lock out while doing maintenance? That is obviously a 1/4 turn valve for pneumatics or hydraulics.

Perhaps something like an oil fired central heating oil supply valve

It's not for air jacks or something like that is it?

 

[John Milmont]

Could this be for injecting oil directly into the exhaust?:idea:

 

[David Morton]

Very similar to the Line lock I have on my front brakes but you are right - it's not for brakes. Could be anything ?

Assuming the police are following you!

Simon.

As above I think it is just an industrial isolation valve with some sort of Locking isolation facility, commonly used on pneumatic machines. locking facility for applying a padlock to allow completion of some form of permit to work system.

we install similar types of valves in the Cement Works that I work in.

I've seen similar valves used on Dirt Late Model and Modified Stock Cars to turn off the right front brake..

Nylon brake lines are actually quite common;

It looks like a light aircraft fuel sample/drain valve, witht the red interlock pin to prevent accidental draining of the tank
