Concertina Dye/oil Injector - Includes Tool / Hose And Coupler

The Concertina is a new cartridge in the form of a bellows. It has no piston, so
there is no opening at the rear. Each pre-filled capsule incorporates a non-return
valve, so there is no mess when you connect it via the charge hose to the system.
As pressure is applied with the injector tool, the capsule collapses like a 1-way
concertina, forcing liquid into the A/C. Once empty, the capsule remains neatly
collapsed, for compact, environmentally friendly (disposal).
