Kobra S1 Upgraded Nozzle & Silicone Sock – 0.2–0.8mm

Anycubic Kobra S1 & S1 Combo Upgraded Nozzle + Silicone Sock Kit

Take your Anycubic Kobra S1 or Kobra S1 Combo 3D printer to the next level with this premium upgraded nozzle and silicone sock set from Sprouture Lab. Available in four precision-engineered diameter options — 0.2mm, 0.4mm, 0.6mm, and 0.8mm — and three high-performance materials, this kit is designed to deliver consistent extrusion, improved print quality, and extended service life.

Why Upgrade Your Nozzle?

The stock nozzle on any FDM printer eventually wears out or limits your filament choices. A purpose-built replacement nozzle matched to your Kobra S1 hotend geometry ensures proper seating, optimal heat transfer, and compatibility with a wider range of filaments — from standard PLA and PETG to abrasive composites.

Three Material Options to Match Your Filament

• Brass Nozzle — The classic choice for PLA, ABS, PETG, and flexible filaments. Excellent thermal conductivity for smooth, consistent flow.
• Hardened Steel Nozzle — Built tough for abrasive filaments such as carbon fiber, glow-in-the-dark, and metal-fill. Significantly extended wear life compared to brass.
• Copper Plate Nozzle — Superior heat transfer with an added protective coating. Ideal for high-temperature printing and demanding materials.

Four Diameter Sizes for Every Application

• 0.2mm — Ultra-fine detail printing for miniatures and intricate models.
• 0.4mm — The versatile standard size; perfect for everyday prints.
• 0.6mm — Faster print speeds with a good balance of detail and throughput.
• 0.8mm — Maximum flow for rapid prototyping and large structural parts.

Silicone Sock Included

The included silicone sock insulates your hotend block, keeping heat stable and preventing unwanted material buildup on the heater block. This results in more accurate temperature readings, cleaner prints, and a longer lifespan for your hotend assembly.

Frequently Asked Questions

Q: Are these nozzles compatible with the Anycubic Kobra S1 Combo as well as the standard Kobra S1?

A: Yes! This upgraded nozzle and silicone sock kit is engineered to fit both the Anycubic Kobra S1 and the Anycubic Kobra S1 Combo. Simply select your preferred material and diameter when ordering.

Q: Which nozzle material should I choose for abrasive filaments like carbon fiber or metal-fill?

A: For abrasive filaments such as carbon fiber, metal-fill, or glow-in-the-dark, the Hardened Steel nozzle is strongly recommended. Brass nozzles wear out quickly with abrasive materials, while hardened steel provides significantly greater durability and longevity.

Q: Does the silicone sock fit all nozzle sizes in this kit?

A: The silicone sock is designed to fit the Kobra S1 hotend block regardless of which nozzle diameter (0.2mm, 0.4mm, 0.6mm, or 0.8mm) you install. It insulates the heater block to stabilize printing temperatures and help prevent filament buildup around the hotend assembly.

Q: Do I need any special tools to install this nozzle?

A: No special tools are required beyond a standard nozzle wrench or socket wrench. Ensure your hotend is at printing temperature before swapping the nozzle so that any residual filament is softened and removal is safe and easy.
