Great value pack

Getting 10 pieces is excellent value. I keep spares on hand because they do wear out eventually with frequent nozzle changes. The silicone quality feels durable and handles ABS printing temperatures well.

Good quality, slight odor initially

The material quality is solid and withstands high heat. There was a slight rubber smell during the first few prints, but it dissipated quickly after a heat cycle. Overall very satisfied.

Improved temperature stability

Since installing these, my temperature fluctuations have decreased noticeably. The insulation keeps the heat focused on the block rather than dissipating into the cooling fan area. A must-have upgrade.

Perfect fit for my V6 setup

These sleeves fit snugly on the aluminum heating block. The split design makes installation incredibly easy without needing to disassemble the whole hotend. Highly recommended for anyone running high-temp filaments.

Essential accessory

If you are using an E3D V6 clone or original, you need these. They protect the heating block and improve efficiency. The pack of 10 will last me a long time.

Easy to install for beginners

I was worried about damaging my hotend during installation, but the flexible silicone made it very forgiving. It snapped right into place. No tools required at all.
