About Guidi Marine Hose & Fittings

Guidi, an Italian manufacturer specializing in marine accessories, offers a comprehensive line of marine-grade brass and bronze fittings, connectors, valves, and strainers. Their fittings are cast from CC499K bronze — a copper-tin alloy specifically formulated for marine environments, giving superior resistance to corrosion, dezincification, and wear in both fresh and salt water settings.

Most of Guidi’s threaded parts use BSP (British Standard Pipe, also known as “G / ISO 228 / BS 21 / EN 10226” threads) standards, commonly used in Europe and marine systems. (Note: BSP is not fully compatible with NPT in the U.S. — sealants or adapters may be needed if mixing thread types.)

Guidi’s hose connectors are dimensioned to allow secure clamping to hose assemblies conforming to nautical standards and to minimize turbulence, cavitation, and pressure drop.

Where applicable, many Guidi products carry RINA (Registro Italiano Navale) validation and conform to UNI EN ISO 9093-1 (the small craft seacocks & through-hull fittings standard).
