Heat Break Thermal Barrier Tubes

Manufactured in the USA by P3-d, these heat break tubes are replacements for v6 Heat Break Tubes.  They are precision machined on swiss CNC lathes and plated with our electroless nickel based Duraplat3-d™ technology, which is used in plastic injection and aerospace RTM carbon fiber molds for its release properties and wear resistance.  We recommend to use these heat break tubes with our low-friction wear resistant nozzles.   Duraplat3-d™ Coating: Specially engineered for improved lubricity and low friction Entirely coated inside and outside High hardness (68Rc) for a lifetime of printing Wear resistant for abrasive filaments (carbon fiber, metallic, etc...)  Corrosion resistant Specs: Fits v6 Hot Ends 303 Stainless Steel M6 threaded body (for 3mm filament) M7 threaded body (for 1.75mm filament
