Marine Grade Butyl Tape for Boat Sealing & Deck Hardware

Permanent Non-Curing: Absorbs engine vibrations and wave impacts. Unlike rigid sealants, it never turns brittle or cracks under structural stress.
Marine-Grade Stability: Specifically engineered for saltwater immersion and intense UV exposure. It won’t melt in tropical heat or fail in cold.
Self-Healing Seal: As bolts penetrate, the tape “hugs” the threads to seal the hole automatically. It flows back to fill voids, preventing deck rot before it starts.
