The Syntho-Plug Football Activated Foam Leak Plug is a water-activated polyurethane foam plug designed to provide rapid temporary sealing of larger punctures, hull breaches, and leak openings. Engineered for marine emergency repairs, spill containment, and leak mitigation, the football-shaped design allows the plug to conform to irregular openings while quickly expanding and hardening to create a durable seal.

Initially pliable for easy insertion, Syntho-Plug activates when exposed to water and cures within minutes, reducing water ingress or liquid discharge from approximately 280 GPM to less than 1 GPM. Compatible with fiberglass, steel, aluminum, and wood surfaces, the plug can be used above or below the waterline in fresh, brackish, or saltwater environments, making it an invaluable tool for emergency vessel repairs and hazardous material containment operations.
