Extruder Compression Spring – 20 mm Length, 7 mm OD, Carbon Steel

The Extruder Compression Spring is a precision-formed mechanical spring designed for use in 3D printer extruder assemblies. Manufactured from 45 carbon steel, it provides consistent tension and durability under repeated compression cycles. Its compact geometry and optimized coil design ensure stable filament pressure and reliable extrusion performance. Built for long-term mechanical stability, it maintains consistent force output across extended use. Ideal for replacing worn extruder springs in most standard desktop 3D printers.
