Sea-Dog Cockpit Scupper 1-1/2in Nylon w/ Flapper
Sea-Dog Cockpit Scupper 1-1/2in Nylon w/ Flapper — Product description
The Sea-Dog cockpit scupper is a simple nylon drain valve for self-bailing cockpits. Water drains out through the opening, and the soft black flapper seals back down to keep it from washing back in. Fits 1-1/2 inch applications and ships as a single unit.
A cockpit scupper is one of those small parts that quietly does a big job. This Sea-Dog scupper drops into a self-bailing cockpit and lets water drain out fast, while the soft black flapper keeps it from washing back in. One-way flow. That's the whole point.
It's molded from nylon, so it won't corrode or seize up the way metal hardware can after a few seasons in salt and sun. The white body blends into most deck colors, and the flexible flapper seals back down on its own once the water's cleared.
This one fits 1-1/2 inch applications and ships as a single unit. Good for replacing a cracked or stiff flapper on an older boat, or rigging up drainage on a project build. If your cockpit's been holding water after a rain or a wet ride, a worn scupper is usually the culprit, and swapping it is a ten-minute job.
Simple part. Does exactly what it should.

Frequently asked questions
What size does this scupper fit?
It fits 1-1/2 inch self-bailing applications.

The soft black flapper works as a one-way valve. It opens to let cockpit water drain out, then seals back down so water can't wash back in through the drain.

No, it ships as a single unit.
