Lectrosonics Replacement O-Ring Set for Transmitters | MM400-Type

Lectrosonics replacement o-ring kits are purpose-built maintenance components for production teams and engineers who rely on Lectrosonics wireless transmitters in demanding live sound, broadcast, and touring environments. A degraded or damaged o-ring compromises the environmental seal of a transmitter body, creating risk of moisture intrusion and unreliable RF performance at the worst possible moment. Having genuine replacement hardware on hand is a straightforward way to extend the service life of existing transmitters without sending them to a repair facility.

These kits are offered in versions matched to specific Lectrosonics transmitter families, so technicians can stock the correct replacement for the units in their inventory. Whether the application is a nightly touring run, a broadcast production floor, or a permanent installed system, keeping o-ring kits in the maintenance kit alongside batteries and antenna hardware is standard practice for any crew taking equipment longevity seriously. Genuine Lectrosonics replacement parts ensure proper fit and seal integrity that generic alternatives cannot guarantee.
