Why Buy Our 1” Boat Drain Tube Flaring Tool?

EASY OPERATION: This tool can create flanges for installing 1" drains in transoms, livewells, or baitwells, making it easy to press in new brass or aluminum drain tubes for a proper fit with no leakage. It lets you flare a 1” OD brass or aluminum tube using two wrenches to tighten the nuts on each end.

DURABLE: It is made of sturdy stainless/zinc-plated steel that can withstand the corrosive elements of a marine environment. Excellent for properly flaring your drain tubes for easy installation and restoration.


  • Once you measured the size you need to install your drain tube flush on your boat, scribe a 2nd line of 3/16” out from the transom line you first scribe for flaring.
