ONE WAY NON RETURN STRAIGHT PIECE VALVE

 Non Return Inline Straight Piece Valve - One way

Will fit tubes 5mm and 6mm

 

Design to stop the back flow of air and water passing back down the pipes or tubes.

Flow is from black to white.

 

NOTE: You will not be able to blow through this valve using your mouth only!

You will be able to suck on the white side and the valve will let a little air through until the spring re-seats the little valve internally.

This takes a quite a lot  of sucking!

Please don't ask me how I know!
