The genuine La Marzocco Tool Conic for Mounting Piston Seals (Part UT016) is the essential, specialized component designed to solve the common service problem of how to install espresso machine piston seals without damage. This OEM tool features a precision-machined conical shape that facilitates the critical process of seal replacement in lever-style group heads, such as those found on the Leva. It works by smoothly dilating the seal's elastic element, allowing the delicate PTFE profile ring or gasket to glide into the designated mounting groove without the damaging twisting or excessive stretching inherent to manual installation. Stop wasting time and money on a damaged piston seal replacement fix. Installing high-pressure piston seals, especially those used in lever machines, is notoriously difficult; improper technique often results in seal deformation, tears, or cuts, leading to immediate leaks and system failure. The UT016 eliminates this risk by providing controlled expansion and insertion support, guaranteeing that the seal is seated evenly and correctly. This precise fit ensures maximum seal life and helps prevent costly leaks after a group head rebuild, significantly reducing machine downtime and ensuring peak espresso quality. This specialized mounting tool is invaluable for technicians and serious maintenance professionals working on La Marzocco piston assemblies. By guaranteeing a quick and safe installation procedure that actively prevents seal damage, the La Marzocco UT016 ensures the mechanical integrity and reliable operation of your high-volume commercial equipment.
