Water Hose Cap for Marine Applications

Protect your shipboard water hoses and couplings with our marine-grade water hose caps. Designed to seal hose ends securely, these caps prevent leakage, contamination, and mechanical damage in demanding maritime environments. Whether you need to blank off a line during maintenance or keep couplings clean from saltwater spray and debris, these caps provide a reliable, watertight solution.

Our water hose caps are manufactured from corrosion-resistant materials including brass, stainless steel 316, and engineering nylon, ensuring long-lasting performance even in harsh saltwater conditions. They are compatible with standard BSP and NPT threads and available in a wide range of sizes from 1/2" to 4" (DN15 to DN100), making them a versatile choice for deck washing, ballast systems, fire fighting, and other shipboard applications.

As a trusted ship chandler, ALL-K MARINE Ship Store supplies high-quality hose fittings and couplings to the marine industry. Each cap is rigorously tested for pressure integrity and durability, so you can rely on them for tough offshore use. Choose from threaded caps for permanent sealing or easy-push caps for quick temporary closures.
