Phaetus EndCoat™ V6 and Volcano Hardened Steel Nozzle (PS & PH Models)

Conquer highly abrasive industrial composites and high-temperature polymers with the ultra-durable Phaetus EndCoat™ Nozzle Series. Available in both standard V6 (PS) and extended Volcano (PH) form factors, these premium nozzles combine a heavy-duty hardened steel substrate with Phaetus's patented EndCoat™ surface technology. The result is a highly resilient thermal component engineered to withstand carbon fiber, glass fiber, and metal-filled materials while maintaining a reliable, high-precision aperture.

Whether you're completing standard prototyping or pushing the boundaries of industrial additive manufacturing, EndCoat™ delivers up to 2.5 times the service life of an ordinary hardened steel nozzle.

🛡️ Patented EndCoat™ Technology

Unlike standard surface plating that can wear down unevenly or peel away under high temperatures, Phaetus's patented EndCoat™ process integrates deep into the nozzle tip and internal filament path. This custom treatment provides unmatched material protection:

• Exceptional Surface Hardness: Delivers a molecular surface hardness rating of approximately HV3300, creating an incredibly tough defense against abrasive additives.
• Slick, Low-Friction Flow: The outer coating reduces physical surface friction to prevent molten polymer from sticking to the tip, decreasing print-head dragging and stringing.
• Corrosion Resistance: Inhibits internal degradation and chemical wear when printing aggressive, acidic, or volatile industrial compounds.

Featuring a microhardness rating of HV3300, EndCoat™ technology yields up to a 2.5x increase in operational service life.

🔥 Built for Extreme Environments

Engineered to handle high-temperature functional 3D printing, the EndCoat™ series keeps running smoothly where standard brass or copper nozzles quickly fail.

• 500°C Thermal Limit: Rated for extreme operating environments, allowing you to confidently print high-temp materials like PEEK, PEKK, PEI (Ultem), and PPSU.
• Abrasive-Optimized Geometry: Precision-machined internal geometry maintains fluid extrusion paths even when printing fibers, reducing backpressure and clogging risks.

📋 Specifications & Compatibility

• V6 Model (PS): RepRap M6x1 standard (7.5mm thread length, 12.5mm total length). Fits standard V6 hotends.
• Volcano Model (PH): Volcano M6x1 standard (14.5mm thread length, 21mm total length). Fits extended Volcano heater blocks.
• Filament Compatibility: Precision engineered for 1.75mm diameter filaments.
• Available Sizes: 0.40mm, 0.50mm, 0.60mm, and 0.80mm.
• Installation Warning: Always hot-tighten to your hotend's precise torque specifications when the heater block is at operating temperature to prevent molten filament leaks.
