Fresh Water Locking Inlet Filler Cap

Fresh Water Locking Inlet Filler Cap Black

Supplied with 2 number coded keys, these caps fit the vast majority of motorhomes - about 85%.

The key is to look for the 3 prongs that stick out on the inside of the cap - the last picture shows the filler on my van - yours doesn't have to look exactly the same as this, but it does need to have the 3 slots around the outside of the central filler hole that these 3 prongs go into.

Please don't message me to ask if it will fit a particular model of van, I can't answer you as manufacturers do change fitments sometimes within a model's lifetime - you'll need to look at the pictures and measurements to tell if it will fit your van.  Returns are allowed if it doesn't fit, providing it comes back still in new condition of course.

The cap is 77mm in diameter at it's widest outer point.  The inside, i.e. the outer edge of the black rubber seal, is 64mm in diameter.  The central protruding part, that goes into the filler neck on your van, is 34m in diameter at it's base, tapering to 29mm diameter just before it's end.

A white version is also available

Make your van much easier to fill with water!  Also consider purchasing our Rheinland filler cap - temporarily replaces your normal locking filler cap so you can attach a hosepipe to it, with a normal garden hose fitting:-
