Guidi Flush Seacock – seawater-resistant brass

Cleanly recessed in the hull, reliable in use: This retractable through-hull fitting from Guidi sits flush with the outer skin and provides a hygienic, corrosion-resistant passage for water and sanitation lines. Thanks to high-quality brass, it withstands continuous contact with salt and brackish water.

Tip: When installing, apply a suitable marine sealant (e.g., polyurethane-based) to the sealing surface and secure the fitting from the outside with a lock nut to ensure permanently tight and secure connections.
