HIROBO HI2529006 O-RING P-3 5pcs Rubber Seal Spare Pack  [HI2529006]

Replacement O-rings for rotorcraft models

This HIROBO HI2529006 O-RING P-3 pack provides five replacement O-rings intended as routine consumables for model helicopter assemblies. It is suitable for small repairs and periodic servicing on model helicopters and similar components that use compact rubber seals.

O-rings are employed to seal linkages, fittings, and maintenance points that require a compressible rubber gasket. Replace them at the first sign of cracking, flattening, or hardening to restore effective sealing and to avoid play in linkages that can impair control accuracy. The 5 pcs pack gives you multiple spare rings for quick field repairs.

Installation is simple: remove the worn ring, clean mating surfaces, lightly lubricate with an RC-safe silicone lubricant if helpful, and fit the new O-ring without overstretching. Always check full range of motion after fitting to ensure no binding or unintended preload.

The product is described solely as an accessory for RC-scale helicopters and is not intended for use on full-size or non-model vehicles.
