Overview
Mike interviews Wes, a grease-industry specialist who brought the Lube Shuttle grease gun to North America, to dig into why modern grease zerks fail more often than older ones. The conversation covers quality-control problems from overseas manufacturing, how zerk head dimensions are supposed to be standardized but often aren't, the main thread types (1/8 NPT, metric M10/M12, BSP, drive-in), how to identify what thread you have using simple hardware-store nuts, and whether adhesives are a bad fix. Useful for owners troubleshooting grease acceptance issues or replacing broken fittings.
