April 11, 2020
Can you please tell me what size is the thread on the fitting. I intend to use it for the drain on my fish well. I plan to cut off the barb hose connection and screw in into a Poly Elbow

Per Perko:


All Perko thru hulls use a National Pipe Straight Thread (NPS).

  • Our 5/8" hose size thru hulls have a 1/2" NPS thread
  • Our 1 1/8" hose size thru hulls have a 1" NPS thread
  • All others use that same NPS thread size as their hose size
    • For example the 3/4" hose size thru hull has a 3/4" NPS thread size.
