Descrizione
A kayak is at its best when the water stays outside. Scupper holes keep a sit-on-top kayak self-draining, but they also let cold spray, sand, and the occasional wave come along for the ride. These 40 mm rubber stoppers close that gap in seconds, turning a wet cockpit into a dry, comfortable seat for long paddles and cold-weather sessions.
The soft, flexible rubber forms a snug seal without marring the hull, and the flanged design holds tight under pressure while remaining easy to pop out with a fingertip. They are built for the abuse of UV, salt spray, and repeated installs, season after season, from flatwater lakes to the surf line.
Each pack carries ten stoppers, enough to cover a full kayak, a tandem, or a spare set for the truck. When the weather turns warm, pull them out and let the scuppers drain freely again; when the air turns cold, plug them in and paddle dry.
Dry legs are the quiet luxury of a serious paddler.

Frequently Asked Questions
Q: Will these fit my kayak?
They fit standard 40 mm scupper holes found on most sit-on-top kayaks. Measure the inner diameter of your scupper hole before ordering to confirm.
Q: Do they keep water completely out?
They dramatically reduce water entry in normal paddling and light chop. In extreme surf or swamping conditions, some water can still enter around the edges, as with any plug system.
Q: How do I install them?
Press each stopper into the scupper hole from the top until the flange seats flush. To remove, pull the tab upward with one finger. No tools or adhesive needed.
Q: Are they safe for the hull material?
Yes. The rubber is softer than kayak hull materials, so it compresses into the hole without scratching gelcoat, plastic, or fiberglass.
Q: Do they float if they pop out?
Rubber plugs typically sink slowly; keep the spares from the 10-pack in your hatch or truck so a lost plug is never a trip-ender.
Q: Can I use them on paddle boards or canoes?
Yes, they also work on paddle board scupper holes, canoe drain holes, and any 40 mm deck drain that needs a temporary seal.
Q: Will the stoppers affect my kayak's stability?
No. They are lightweight and sit flush with the deck, so tracking, stability, and hull performance remain unchanged. They only change what happens below deck, keeping water out.
Q: How do I store them between paddling seasons?
Rinse with fresh water after saltwater use, dry them completely, and store them out of direct sun in a cool, dry place. Stored properly, they keep their shape and sealing performance for years.
