  • Do this bulkheads fit perfectly on a 1.5 inch hole?. I have been looking everywhere for a 3/4 bulkhead for a 1.5 hole as opposed to the 1 3/8 hole.
  • Yes, this bulkhead fits in 1.5" hole.

  • Hello. On this bulkhead, the insert fitting appears to be threaded both inside and outside. I am assuming the inside threads are 3/4" NPT? If so, what are the outside threads? Basically, I am wondering if an FPT elbow can thread directly onto the outside of the of the threads protruding to the dry side of the tank. Thank you!
  • Ron,
    Inside threads are 3/4". Outside thread is not compatible with any of the PVC fittings. It only fits bulkhead nut.
