P-16 O-ring set 5 pcs for Hirobo HI2529004  [HI2529004]

P-16 seal rings for routine service

This Hirobo HI2529004 kit provides five P-16 O-rings intended for general helicopter maintenance and small seal duties. Use them as spare parts for Hirobo helicopter assemblies or other small RC items that specify the P-16 size.

Installation is simple: remove the old ring, clean the seating area, and install the new O-ring ensuring it sits evenly without twists. If the assembly recommends it, a small amount of silicone-compatible grease will help the ring seat and reduce initial wear.

O-rings like these are maintenance items rather than tuning components; they maintain fluid containment, help dampen light vibration where mounted, and preserve correct clearances. Carry a few extras in your tool kit for quick swaps during maintenance or events.
