This product is compatible with the E3D cartridge style heater block on the V6. If you have an older bead style heater block, we have an upgrade kit available here.
For those who have printed with copolyesters like colorFabb XT, you know that if you don't nail the settings absolutely dead on, the nozzle can pick up little bits of material throughout the print. The bits collect until they are big enough to be dropped off in a gooey char blob. Doesn't usually matter much for function, but for looks it's not great.
The silicone socks help to address that issue with a non-stick surface that covers most of the nozzle and heater block leaving only a little bit of the end of the nozzle sticking out.
The sock also provides the additional benefit of insulating your heat source. This allows for more cooling of your print for better bridges and overhangs without the concern of accidentally cooling your nozzle and causing temperature fluctuations (or the dreaded temp fall error). It also insulates your part from the heat generated from the heater block which will cause some improvement in quality.
It is expected that this sock may become worn or damaged over time, and they're cheap enough that the shipping is more than the cost of one piece, so we've bundled them into multi packs. Your future self will thank us.
