Seachoice Screw-Type Drain Plug with O-Ring Seal
A reliable, positive-sealing drain plug for boat transoms, fish wells, ice chests, and other onboard compartments that require a secure, vibration-resistant drain closure. The screw-type design with fine threads and an integrated O-ring seal keeps water out even under the constant vibration and movement of underway conditions — and the attached plug means you won't lose it overboard during draining.
Parts Desk Insights
This is the correct drain plug when you need a secure, watertight closure in a 1" diameter drain hole and want a plug that stays attached to the fitting when removed. The fine-thread screw design is specifically suited to high-vibration applications where a push-in or friction-fit plug would work loose over time — making it the preferred choice for transom drains and fish well drains on trailered boats that see regular road vibration. The two-screw flange mount (1-1/2" x 2" flange, two #8 screws) provides a secure, flush installation. Confirm your drain hole is 1" diameter before ordering.
