Brad Ultra-Lock Connectors

Molex Brad Ultra-Lock Connectors incorporate a mechanical locking design and a unique radial-seal that deliver unsurpassed performance. The patented push-to-lock technology provides a simple and secure operator-independent connection. This positive locking design provides built-in reliability that eliminates connector related intermittent signals in the harshest environments. Fewer intermittent signals mean less downtime and better productivity. The unique radial o-ring seal design, similar to what is found in hydraulic connectors, provides a more robust protection against water ingress even in high-pressure wash-down environments.
