Full-Thread Thru-Hull Flush Deck Drain Fitting.
Unlike the previous models with a ribbed hose barb, this version features continuous external threading down the entire length of the shaft. It is designed to mount flush on a deck, floor, or hull wall, allowing you to directly thread on a female pipe coupling, an elbow fitting, a sea valve, or a specialized drainage pipe rather than sliding a flexible hose directly onto it.

To ensure the parts mate perfectly with your plumbing system, could you tell me:
• What is the thread size or hole diameter you require (e.g., 1/2", 3/4", 1", 1-1/2" NPT/BSP)?
• Are you planning to thread a female coupler/valve onto the end, or do you still need to attach a flexible rubber hose down the line?
