Marelon® - Marine Grade Plumbing Systems

• Non-Corrosive
• Non-Conductive
• Fire Resistant
• Impact Resistant
• Temp. Range -40° to +250° F
• U.V. Resistant

In the late 1970's, a search was undertaken for a material that could replace the traditional bronze and brass plumbing components in boats. The frequency of severe corrosion, and the problem of conductivity in bronze, had long been a source of frustration for designers and boat builders. And, owners had to deal with the risk and costs of this ancient metal in their modern boats.

Marelon® is a formulation of glass reinforced Dupont Zytel®. It is optimized for marine use above and below the waterline with maximum U.V. inhibitors, and it will not support combustion. Additional marine benefits of the material are its extreme range of operating temperature and it's resistance to abrupt changes in temperature.

Over the years there have been many thousands of installations exposed to the extreme cold experienced in Alaskan and North European fishing boats, and to the high temperatures of marine engines and exhaust systems. We know of no case of failure of a Marelon® component from weathering or from these extremes of heat or cold.

Critical Marelon® plumbing components are U.L. marine listed (MQ1151R) and exceed A.B.Y.C. (H-27) (American Boat & Yacht Council) standards. See product catalog for listings.
