B&G SEN-PLUG-DPT Depth Transducer Housing Plug

B&G Housing Plug for Depth Transducers (SEN-PLUG-DPT)

The B&G SEN-PLUG-DPT is an essential Blanking Plug / Dummy Insert engineered to maintain watertight hull integrity when a depth sensor or combination transducer is removed from its thru-hull housing. Designed specifically for B&G and Airmar 2-inch (51 mm) depth housing assemblies, it seals the internal bore of the thru-hull fitting during sensor maintenance, off-season storage, or dry-docking.

Constructed from heavy-duty, UV-stabilized marine composite polymer, the SEN-PLUG-DPT includes integrated O-ring seals and a safety locking cap/ring to prevent accidental dislodgement under hydrodynamic water pressure. Utilizing the dummy plug prevents marine fouling, barnacles, and debris from colonizing the inside of the housing bore while the primary transducer is uninstalled.

Key Features

• Watertight Hull Protection: Safely seals open thru-hull housings when depth transducers are pulled for cleaning, inspection, or winterization.

• Fouling Prevention: Keeps marine growth, algae, and debris out of the internal housing mechanism while the main sensor is removed.

• Dual O-Ring Seals: Features high-grade marine nitrile O-rings to ensure a leak-proof seal under dynamic hull loads.

• Durable Marine Composite: Corrosion-free polymer construction engineered to resist UV degradation and saltwater environments.
