Waterproof Tackle Box Gasket & O-Ring Seal Kit – 60-Piece Multi-Size Replacement Set

Keep Your Gear Dry & Protected

Waterproof seals are what stand between a ruined day and a successful haul. This 60-piece O-ring gasket kit replaces worn or damaged seals on hard tackle boxes, dry bags, and waterproof organizers—the backbone of reliable gear storage. A cracked or degraded gasket turns a waterproof container into a water-trapper. These replacement seals slip in fast, cost pennies on the dollar versus a new box, and keep your tackle, electronics, and essentials bone-dry in rain, spray, or rough conditions.

What's Inside

• 60 black rubber O-rings & gasket seals in 4 universal diameters: 5/16 in (8mm), 3/8 in (10mm), 15/32 in (12mm), and 9/16 in (14mm)
• Premium rubber construction resists UV radiation, saltwater exposure, and temperature extremes
• Universal fit for most hard-sided tackle boxes, coolers, waterproof cases, and dry bag closures
• Replace worn seals without replacing the entire container

Why Seal Replacement Matters

Over time, gaskets and O-rings degrade from UV exposure, salt spray, and thermal cycling. Replacing them restores the waterproof integrity of your storage system, protecting expensive tackle and gear from moisture damage. This assortment covers the most common seal sizes found on fishing tackle boxes, coolers, and waterproof organizers.
