Behold the Mosquito® Liquid - it uses the same patented technology found in the standard, air-cooled Mosquito® hotend, but optimized for liquid cooling in heated enclosures. The liquid cooling block is precision machined out of a corrosion resistant bronze alloy that allows for use with most commercially available coolants. Liquid also features our latest Bimetallic Heat Break™ - the first version to be totally conductively cooled. The hotend is available with or without liquid fittings. Includes: Mosquito® Liquid - 1.75 (Fully assembled) Mosquito® Liquid Mounting Hardware Set of Mosquito® Liquid hex keys for assembly, disassembly, and mounting Super tasty US-made gourmet lollipops Eisele Fittings (if selected) Mass Specifications: Hotend mass: 74 grams Hotend mass w/ 6 mm OD Eisele Straight Fittings: 99 grams Hotend mass w/ 8 mm OD Eisele Straight Fittings: 108 grams Hotend mass w/ 6 mm OD Eisele Elbow Fittings: 122 grams Hotend mass w/ 8 mm OD Eisele Elbow Fittings: 158 grams General Notes: If using Eisele Fittings, the compression side should be hand tightened and the threaded side should be torqued to a maximum of 9 Nm for a proper seal. If using these compression fittings with a tube material that has a Durometer of 95A or softer, a tube support will be necessary in order to properly secure the tube within the fitting. If using a tubing softer than 95A, we tested and recommend Viton® fluoroelastomer tubing with a Durometer of 75A. The Mosquito® Liquid is compatible with Rep Rap style nozzles which are characterized by their M6 x 1.0 threads, 7 mm threaded length, and 12.5 mm overall length.
