2-Pack Compression Kayak Scupper Plugs
Perfect for problem scupper holes or those prone to knock-outs.
Today’s kayaks dwarf what was available in the past with constant innovations and advanced features. Many of which are borrowed from larger traditional power boats. Compression plugs have been used for years on larger boats and this technology has now been brought to the kayak segment. They are ideal for scupper holes that tend to leak or in applications where the scupper plugs are easily knocked out. These plugs use corrosion-resistant 316 stainless steel for all metal components which is the most durable for marine applications. When tightened with the supplied Allen-wrench, the rubber plugs bulges to form a tight and secure seal.
The compression plugs can only be removed from below the kayak and require the use of an Allen-wrench to loosen. For your safety you should remove the compression plugs prior to entering rough water conditions where the open factory equipped scupper holes can function as designed to drain large amounts of water quickly.
Sold in packs of two, these plug have a slight taper for a tight fit when installed. This is better than universal plugs with an extreme taper because those plugs tend to not hold as secure which makes them prone to leaking and becoming dislodged easily. Each set includes an Allen-wrench for installation.

When measuring…
Be sure to check each scupper hole to be plugged. They can and do vary from hole to hole.
Measure to the nearest 1/8” at the section of the scupper hole where it is completely round and begins from a straight cylinder wall. You can download our Scupper Hole Size Gauge free of charge to help with the measurements.
Select a plug size that has your scupper hole measurement somewhere near the middle of the taper range. For example if your scupper hole is 1-1/4”, you would want to select our 1-3/16” - 1-7/16”. This means that when the plug is installed, it will be approximately halfway in. If a larger plug is selected it will sit too high and be easy to be knocked out. If a smaller plug is selected it may sit lower but it may also not be large enough to press tightly in the scupper hole for a proper seal.
