Bulkhead ABS Thread x Slip (Thread on the Flange/Head side)

When measuring for bulkheads, you will need a hole in your tank that is slightly larger than the “C” measurement for the corresponding bulkhead but no larger than the “A” measurement. 

Example: If you have a 1.75″ diameter hole currently in your tank, then you would want to use the 1″ ABS Bulkhead.
