This is a direct replacement part for the WHITE ink dampers found in your DTG Viper garment printer. This special damper has a special heat-shrink bonding that helps seal the tubing once slid over the top and OVER the bottom flange of the 'spout'. Helpful tip: use mouth supplied spit to help lube up the spout in order to slide the tubing over the flange.
LOOK VERY CLOSLY AT THE DAMPERS ON YOUR PRINTER BEFORE ORDERING. DTG uses a number of different types and setups in their printers.
