CONCERTINA DYE INJECTOR with UV TORCH

Concertina adds measured amounts of Glo-Leak UV test fluid, PAG oil, Ester oil or other lubricants, without degassing, and without adding refrigerant. (The law requires you to leak test before topping up refrigerant) The factory pre-filled Concertina cartridge collapses as the liquid is forced out by back pressure or drawn out by vacuum. It stays collapsed thanks to the valve built into the bottle cap. This allows the liquid out, prevents air and moisture entering in. This also helps to prevent use of the wrong lubricants.
