The XRAY 971240 Silicone O-Ring set contains ten precision rings cut for a 24mm diameter shaft with a 0.7mm cross section, made to keep rotating parts sealed and running clean. These O-rings are a simple spare-part solution for hobbyists carrying out scheduled service or quick swaps at the track.
Silicone construction delivers good resistance to heat and aging while remaining flexible for secure seating. Use them to replace worn seals around shafts, gearboxes, or differential components without needing specialist tools.
Sized for a snug fit on 24mm shafts, these rings suit a wide range of RC models where a thin 0.7mm wall is required. They are especially handy for model builders and tuners who want reliable sealing against dust and light moisture.
