Light Monkey Blind Plugs

An E/O blind plug is a protective cap designed to seal wet-matable Electro-Oceanic (E/O) cords when they aren't actively plugged into a light head, battery canister, or heated vest system. It keeps salt water, dirt, and debris away from the exposed electrical pins, preventing costly galvanic corrosion and pin damage while your technical diving gear is stored or transported.

Light Monkey E/O Blind Plug

Protect the most critical electrical connections in your technical diving setup with the Light Monkey E/O Blind Plug. Designed specifically for wet-pluggable E/O cord systems, this dummy plug seals and insulates exposed connectors when not in use—shielding fragile pins from saltwater exposure, sand, impact, and corrosion.

Whether you're running heated undergarments, switching out canister light heads, or storing your battery pack between dives, keeping an E/O blind plug attached ensures your connectors stay clean, dry, and ready for your next dive.

Key Features & Benefits

Corrosion Protection: Seals out moisture and salt spray to eliminate galvanic corrosion on electrical contacts.

Debris Barrier: Blocks sand, grit, and dirt from fouling female sockets or bending male pins during transport.

Universal Compatibility: Fits standard wet-pluggable E/O cords used on technical dive lights, battery canisters, and heated drysuit systems.

Durable Construction: Made from marine-grade materials designed to withstand harsh saltwater and technical diving environments.

Essential Gear Safety: Inexpensive insurance against permanent connector damage and mid-trip electrical failures.

Recommended Uses

Capping unused drysuit heated-vest leads on dives where active heating isn't required.

Protecting battery canister outlets when light heads are detached for storage or charging.

Safe storage and transport in your gear bag or dive crate.
