That Vetus sea chest comes in 3 sizes. Maybe Amel used different sizes at different times and models. Maybe not.
The outlet of our sea strainer is 1 1/2 inch BSP.
In this size, BSP and the US Standard NPT have identical thread pitch and depth, but different thread shapes. You can screw either one into the other with full mechanical strength, but they will not seal reliably leak tight using only TFE tape. For low pressure applications (like the sea strainer) use of a good pipe sealant paste will give a permanent leak tight seal.
