Sea-Dog 520021-1 Replacement Drain Plug 1 Inch Nylon
Sea-Dog 520021-1 Replacement Drain Plug 1 Inch Nylon — Product description
Lose the plug on your Sea-Dog drain fitting and you're stuck. This is the exact threaded screw-in replacement for the 520010, 520020, and 520030 drain plugs, and it comes with a fresh gasket. UV-resistant nylon, one inch, hand-tight. Keep a spare in the dry box.
Lose the plug off your Sea-Dog drain fitting and the whole assembly is useless. This is the fix. It's the threaded screw-in plug that replaces the one on Sea-Dog's 520010, 520020, and 520030 drain plugs, and it ships with a fresh gasket so you get a clean seal the first time.
The plug is molded from nylon and UV resistant, so it holds up to sun and spray without going brittle on you. One inch in diameter, it threads right into the matching flange and snugs down by hand. No tools, no fuss.
Keep one in the dry box. These plugs walk off, get dropped overboard, or finally wear out their gasket after a few seasons, and when that happens you want the spare already aboard instead of a bilge that won't drain.
