Valox Shore Power Inlet (Round, Male 16A 230V) – Marine Flush Connector

This 16A round-front shore power inlet provides an alternative form factor to the standard square inlet, featuring a circular flange that can be easier to install on certain boat surfaces. The inlet is made from durable Valox® thermoplastic, offering the same robust, corrosion-proof performance as the square version. It mounts flush with a round cutout – an ideal solution if your boat already has a circular hole or you prefer a round design for aesthetic or space reasons. The unit is a male 3-prong inlet for 230V AC shore power, complete with a tethered watertight cap that ensures IP56 protection when closed against water and debris.

Like other Marinco 16A inlets, this round Valox model uses nickel-plated brass pins internally to guarantee secure electrical contact and longevity. Its heavy-duty plastic construction stands up to UV rays, saltwater, and physical impact, making it suitable for all marine environments. The locking cover keeps the inlet dry and safe when not in use. If your boat originally had a round shore power inlet or you have limited flat area for installation, this product provides the perfect solution without sacrificing quality or water tightness. It connects with any standard 16A shore power plug for easy power hookup.

Use Cases and Recommendations :

• Ideal replacement or upgrade for boats that require a round shore power inlet – for example, if a previous inlet left a round cutout, this Valox unit will fit directly without modification.
• Useful for installations on curved hull sections or where space is limited, as the circular flange can provide a better seal or fit than a square one.
• Perfect for maintaining a uniform appearance on a vessel where other deck hardware (hatches, fillers, etc.) is round – this inlet blends in better aesthetically while still providing full 16A shore power functionality.
• Suited for the same range of boat sizes and power needs as a standard 16A inlet (boats up to ~12 m with moderate AC systems). It provides a reliable 230V connection for running chargers, outlets, and appliances at the dock.
• Interoperable with Marinco and standard systems – you can use your existing 16A dockside cord. The round shape is purely a mounting preference; electrically this inlet matches the standard 16A shore power connector.
