Guidi Marine Fittings

Guidi Logo

Environmental Marine is proud to offer high-quality Guidi marine fittings, designed for the harsh environmental demands of marine use. These corrosion-resistant CC499K bronze fittings, strainers, valves and accessories will perform reliably for years.

Guidi Bronze Fittings

We recommend Guidi brand bronze fittings because of the harsh, salty conditions and temperature extremes your boat or yacht will likely encounter. Bronze offers superior resistance to corrosion and wear and can withstand high pressure, making it perfect for use in marine plumbing. Unlike plastic fittings, bronze is strong, malleable and durable — ensuring its usefulness over years of operation.
