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

RC helicopter O-ring maintenance kit

This HIROBO HI2529006 O-RING P-3 pack includes five replacement O-rings intended as consumable seals for general RC helicopter parts. The set is designed for routine checks and minor repairs on model helicopters and other compatible assemblies that use small rubber seals.

O-rings seal linkages, fittings, and service points where a compressible rubber gasket is required. Replace them when they show cracking, flattening, or hardening to restore reliable sealing and to prevent play in linkages that can reduce control precision. The pack contains 5 pcs so you have spare rings for several quick repairs.

Fitting is straightforward: remove the worn ring, clean the mating surfaces, apply a light coat of RC-safe silicone lubricant if needed, and fit the replacement without overstretching. After installation, check full range of motion to confirm there is no binding or unintended preload.

The description treats this item strictly as an accessory for RC-scale helicopters and does not imply suitability for full-size or non-model vehicles.
