Reliable Watertight Protection – with gasket and sealing cap

A compression gasket and a watertight sealing cap create a physical barrier that prevents ingress when the plug is not inserted. The cap locks over the receptacle to shield contacts from spray and moisture.

Secure sealing reduces corrosion risk and improves longevity of 12V connections in marine or exposed outdoor settings.

Flexible Installation Options – with supplied mounting plate or locking ring

A mounting plate is included for neat front-panel installation, while a locking ring allows secure rear access fitting into panels. Both accessories remove the need to source extra brackets during installation.

Fitting can be completed quickly on dashboards or bulkheads, whether access is from the front or rear of the panel.

Appropriate for Standard 12V Circuits – with a 20 amp maximum rating

Rated for 12V systems and specified with a 20 amp maximum, compatible with common 12V plugs used across boats and vehicles. The rating indicates safe continuous current the receptacle is designed to handle.

Suitable for most accessory loads such as lighting, pumps and chargers that fall within the 20 amp limit.
