Bulkheads Specifications

Leave the tape measure in the toolbox.

Bulkhead fittings are sized by the nominal PVC pipe they accept, not their actual outside dimensions. A 1" bulkhead fits 1" PVC pipe, not a 1" hole.

The measurement that matters? Your tank's mounting hole. Refer to the required hole size shown in each diagram before drilling.
