This is a custom made water tank fill made from aluminum with a stainless steel cap. Both will polish up or can be left dull. Inside neck is long enough to go through thick sidewalls, like Spartan, or can be cut down. Uses 1-1/4" ID clear PVC hose for connecting to fresh water tank (available on-line here also). The flange and tube are welded together but the weld is on the inside now so it looks nicer on the outside. (One photo shows old style with weld on outside). The portion that will stick out on the outside of the trailer is approximately 2-3/8" at the farthest point including the cap.
Application: Any vintage trailer which needs a period looking water fill.
Height: 3-1/2" Flange
Width: 3-1/2" Flange
Depth: 9" total length
