Hirobo HI2529007 O-RING P-22 Linkage O-ring Kit for Helicopter Spares  [HI2529007]

Compact O-ring Kit for Routine Servicing

This Hirobo HI2529007 O-RING P-22 is supplied as a small rubber o-ring pack aimed at general helicopter maintenance tasks. It is suitable for replacing hardened or worn seals where a snug elastic seal is required in confined spaces.

Workshop applications typically include sealing small control linkages, keeping dust away from tiny rotor bearings, and re-establishing preload on softer joints. The item is sold as a generic replacement for helicopter assemblies, so confirm the o-ring fits the intended joint before installing.

Installation notes

• Take out the old o-ring and thoroughly clean mating surfaces to remove grime and old lubricant.
• Apply a light smear of silicone grease to the new o-ring to help it slide on and reduce the risk of pinching.
• Stretch the o-ring gently and seat it on the shaft or inside the groove, then check for free movement and that there is no binding.

Tuning and maintenance role

Fresh o-rings restore sealing and reduce unwanted play in small mechanical joints; fitting new rings can improve consistency of movement and reduce contamination problems. Store a few spares for regular checks and quick trackside fixes.
