In a barrel All metal input Teflon only reaches the top of the barrel, the rest of the route is done through the metal interior of the barrel, prevents the inlet Teflon from touching the nozzle making it suitable for high temperatures at which Teflon can degrade. This type of barrel It may require a few degrees more temperature and is usually more prone to clogging than a heatbreak Bore type.
Titanium improves heat evacuation over heatbreak This means that there are greater temperature differences between the block and the heatsink. By not having parts of different materials such as a barrel BiMetal, has a longer life span (but worse thermal conductivity)
Material: Titanium
Bottom Diameter: Threaded M6
Top Diameter: M7 Smooth
Caliber 1.75mm
Length: 20.9mm
*The use of thermal paste at the junction with the heatsink is recommended
