There are several factors to consider with the hole size needed for a bulkhead. The information below is considered "general" guidelines for the most popular types of bulkheads. (For example they may not apply to schedule 80 bulkheads).
- 3/4 inch bulkhead: 1 1/2 inches (thick walled bulkheads need 1 3/4 inch hole)
- 1 inch bulkhead: 1 3/4 inches
- 1 1/2 inch bulkhead: 2 1/2 inches
Be sure to check with your supplier before ordering, and be sure to have bulkheads in hand before having a tank custom drilled!!
