The Cometic left side case gasket for Honda TRX400EX is an AFM-style seal formed from chemically blown nitrile synthetic rubber bonded to an aluminum core for consistent sealing under load. AFM construction provides strong recovery and torque retention with heat resistance above 205°F and typically eliminates the need for sealants or re-torquing. Intended for 1999–2006 TRX400EX left side case service where a durable case seal is required.
