Marine-Grade 316 Stainless Steel Full Threaded Thru-Hull Fitting (Drain Outlet), heavily utilized in boat plumbing systems for bilge pumps, deck drains, or livewells.
Its mirror-polished surface offers top-tier corrosion resistance in harsh saltwater environments. The full-length thread design allows you to adjust the backing nut to accommodate various hull or transom thicknesses seamlessly.
• Common Thread Sizes (O.D.): 3/4", 1", 1-1/4", 1-1/2", and 2" (Standard BSP or NPT threads).
• Key Installation Feature: The interior of the flange head features dual internal slots/pins. This allows an installation tool or a wrench to lock the fitting in place, preventing it from spinning while you tighten the nut from inside the hull.
To help you find the exact replacement or purchasing link, could you tell me:
• What is the diameter of the hole drilled in your hull (or your target thread size)?
• Will this be installed above or below the waterline?
