These John Guest 4mm Half Cartridges are what's used in the new EZRstruder as well as our new HE series hotends. They allow the 4mm PTFE tubing to pass thru giving a fully lined path for filament to travel reducing friction and chances for jamming. Sold individually, they press into an 8mm hole and have a plastic retainer with metal barbs that engage to hold the tubing. Search for our lanyard for PTC fittings to give you a positive locking connection on these fittings
