Micro Stainless Steel Extension Coil Spring, OD 2mm, 0.3mm Wire Diameter, 6.56ft, Rust-Proof, Flexible Hose Guard for Capillary Tubes and Sensor Wires

This micro extension coil spring is crafted from 304 stainless steel, delivering reliable rust-proof performance and long-lasting durability. With a slim outer diameter of 2mm and a wire diameter of 0.3mm, it is perfectly sized to fit snugly around tiny capillary tubes, 3D printer PTFE lines, sensor wires, and micro air hoses, effectively preventing kinking, abrasion, and bending damage to delicate internal pipelines and fragile cables. The total length of 6.56ft is supplied as one whole, uncut piece, giving you full wrapping protection and the flexibility to cut it to your exact needs. Both ends can be bent into small hooks, allowing it to double as a tension pull spring when required. Its uniform elasticity and light tension make it an ideal fit for tight mounting gaps found in lab equipment, RC drones, hobby DIY assemblies, and other precision applications. The sturdy coil structure ensures consistent protection across the entire length, making it a versatile and dependable solution for a wide range of micro-scale projects.
