Manufactured from Marelon, Forespar’s advanced glass-reinforced polymer, this valve provides excellent resistance to corrosion, electrolysis, and harsh marine environments. Unlike metal fittings, Marelon components will not corrode or seize, making them particularly suitable for long-term installation in sanitation systems.

The valve operates through a simple manual lever that clearly indicates the selected flow direction, allowing quick and secure switching between discharge routes. It is commonly used in combination with marine toilets such as Jabsco manual and electric toilet systems, where a Y valve is required to comply with different waste management setups.

Available in two sizes to suit standard marine sanitation hose diameters, the Marelon Y valve is widely used in both sailboats and motorboats due to its durability, smooth operation, and dependable sealing performance.

Loctite® 577 is a high-performance thread sealant designed for sealing metal threaded pipes and fittings, preventing leaks caused by vibration, pressure, or temperature changes.

Commonly used in marine plumbing, hydraulic systems, and gas installations, it provides reliable sealing while also locking the threads to resist loosening. The sealant cures anaerobically in the absence of air when confined between metal surfaces.

Supplied in a 50 ml bottle, Loctite 577 allows for accurate application and is suitable for both maintenance and installation work on board.
