Draper Cranked Immersion Heater Spanner Metric 85mm

About this tool

The Draper Cranked Immersion Heater Spanner is a specialist tool designed for the installation and removal of electric immersion heaters fitted to domestic hot water cylinders with moulded insulation. This professional-grade spanner is essential for plumbers and heating engineers working with standard UK immersion heater installations. Manufactured from robust 3mm thick steel with a protective zinc-plated finish, this tool delivers the strength and corrosion resistance required for reliable performance in demanding plumbing applications. The cranked handle design provides additional leverage and torque, making it easier to loosen tight immersion heater elements without damaging the cylinder or surrounding insulation.
