Marelon - Marine Grade Seacocks
Non-Corrosive Non-Conductive Fire Resistant Impact Resistant Temp. Range -40 to +176 degrees F U.V. Resistant 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.
Marelon is a good substitute for bronze seacocks. It is unaffected by electrolysis- so there is no need for a bonding wire. Also, corrosion of any kind is not a problem. A light lube from time-to-time is all the service needed.
