Hotend Silicone Sock - H2D / H2S / P2S / X2D - 1 piece

Hotend Silicone Sock – H2D / H2S / P2S

A silicone sock for the hotend is a small but very effective accessory for Bambu Lab 3D printers. It protects the hotend block and nozzle, improves thermal stability, and keeps the hotend clean even during longer prints. This version is designed for H2D / H2S hotends (H2 series) and the P2S model. Thanks to its precise shape, it simply slides onto the hotend block and stays firmly in place even during fast printing.

Main benefits of the silicone sock

• Better thermal insulation – the silicone creates an insulating layer around the hotend block, which helps maintain a stable temperature even at high filament flow rates.
• Protection against cooling air – the sock protects the nozzle and block from direct cooling air flow from the fans, which reduces temperature fluctuations.
• Less plastic adhesion – melted filament is less likely to stick to the surface of the sock, so the hotend stays clean longer and is easier to maintain.
• Longer hotend life – limiting plastic buildup and more uniform heating contribute to a longer life for both the nozzle and the heating block.
• Quick and easy replacement – if damaged or worn, simply pull the sock off and put on a new one.

Material properties

The silicone sock is made of heat-resistant silicone, commonly used in original Bambu Lab replacement parts for the H2 series. The material is designed to:

• withstand long-term load during printing up to approx. 300 °C,
• be flexible and tear-resistant,
• seal well around the hotend block and not peel off during print head movement.

Compatibility

• Bambu Lab H2D hotend
• Bambu Lab H2S hotend (and other compatible H2 series variants)
• Bambu Lab P2S (hotend part compatible with this silicone sock)

Before installation, we recommend verifying the hotend type matches the H2D / H2S / P2S designation in your printer.

Package contents

• Hotend silicone sock – 1 piece

Tips for use

• Install the sock on a cooled hotend to prevent burns or damage to the material during assembly.
• After installation, check that the edge of the sock does not interfere with the filament path at the nozzle and does not obstruct material flow.
• When printing abrasive or high-temperature filaments (e.g., PC, PA, CF filled materials), regularly check the condition of the sock and replace it as needed.

This silicone sock is an ideal solution for Bambu Lab printer users who want to increase printing reliability, improve the surface quality of prints, and simplify hotend maintenance.
