Silicone sock cover for MK7 MK8 heated blocks

This blue silicone sleeve fits MK7 and MK8 heated blocks on 3D printers. It insulates the aluminum heating block during operation. The cover is sold as a single piece without the heated block included. It suits hobbyists and professionals maintaining or upgrading their printer hotends.

Thermal insulation during sustained printing

The silicone material wraps the heated block to retain heat during long print jobs. Stable block temperature reduces filament flow variation across layers. This helps consistent extrusion when printing for extended periods. The cover stays in place through repeated heating and cooling cycles.

Low thermal mass and simple handling

The thin silicone sleeve adds negligible mass to the hotend assembly. It does not increase power draw or require additional cooling. Installation is a quick push-fit over the existing block. The blue colour makes the cover easy to spot during maintenance.

Questions about this item

Does the 1.3 cm thick silicone sleeve trap heat around the heated block during long prints?

The 1.3 cm thick silicone sleeve is designed to insulate the heated block, helping maintain stable temperatures and reduce heat loss during extended printing sessions.

Which heated block models does this 2.3*2.3*1.3CM blue silicone cover fit?

This cover is made for MK7 and MK8 heated blocks; the block itself is not included in the package.

Will the blue silicone cover interfere with the thermistor or heater cartridge wires on an older MK7 hotend?

The sleeve slides over the aluminum heating block, leaving openings for the thermistor and heater cartridge leads to pass through without interference.
