For model builders who service parts regularly, the XRAY 972050 Silicone O-Ring set is a practical spare. These rings are designed for 5mm shafts with a 2mm profile to provide a reliable sealing surface in many RC setups.
Moulded from quality silicone, the O-rings cope well with the wear of repeated assembly work. Their flexibility and tear resistance mean they sustain a good seal through servicing routines.
Keep a pack of XRAY 972050 O-rings in your spares kit for fast repairs or part swaps. They help prevent lubricant loss and secure components so your model runs cleanly.
