P-16 O-ring Replacement Set (5) Hirobo HI2529004  [HI2529004]

P-16 replacement rings for small RC assemblies

This Hirobo HI2529004 set features five P-16 O-rings intended for general maintenance and sealing duties in helicopter assemblies and similar small RC components. The parts are supplied for use as spare seals during routine servicing.

Removal and replacement are straightforward: take out the old O-ring, clean the contact area thoroughly, and press the new ring into place ensuring it is not twisted. If recommended for the assembly, apply a small amount of silicone-safe lubricant to assist fitting and to protect the material.

O-rings are maintenance consumables rather than performance upgrades; they preserve fluid containment, help isolate minor vibrations, and ensure correct component spacing. Keep extras in your workshop for prompt replacements and dependable intervals between services.
