Replacement 3x42 o-ring details

This Zenoah K700013042 O-ring serves as a direct replacement sealing part for RC use, intended for routine maintenance and small component repair. The item is supplied as a single 3x42 sized sealing ring to restore or maintain seals in assemblies that specify a 3x42 o-ring.

Installation is straightforward for hobby technicians: clean mating surfaces, inspect for wear or debris, seat the o-ring into its groove without twisting, and reassemble to achieve even compression. The ring restores proper sealing and does not change tuning or performance beyond correcting leaks.

Storage and care: avoid prolonged exposure to solvents and direct UV light, keep the ring stored flat at ambient temperature, and replace any o-ring that shows cracking or permanent deformation. Confirm fitment with the component reference that specifies a 3x42 o-ring.
