HIROBO HI2529006 5-Pack O-Ring P-3 Rubber Seals  [HI2529006]

Seal set for model helicopter upkeep

This HIROBO HI2529006 O-RING P-3 kit supplies five replacement O-rings intended as standard consumables for RC helicopter components. It is suitable for periodic inspection and small repairs on model helicopters and other systems that use similar rubber seals.

O-rings are used to maintain seals around linkages, fittings, and service points that need a compressible rubber gasket. Replace rings that show cracking, flattening, or hardening to restore a reliable seal and to prevent slack in linkages that can affect handling. The 5 pcs count gives you enough spares for multiple service intervals.

Installation requires removing the worn ring, cleaning mating faces, optionally applying a small amount of silicone lubricant safe for RC, and seating the replacement without excess stretch. Verify full movement after fitting to ensure freedom of travel.

This entry describes the item solely as an RC-scale helicopter accessory and is not an endorsement for use on full-scale or non-model vehicles.
