Frequently Asked Questions
What is Marelon and why is it used in seacocks?
Marelon is a high-performance polymer compound developed for marine applications, offering superior corrosion resistance, impact strength, and UV stability compared to traditional metals. Its use in seacocks eliminates galvanic corrosion and the need for periodic cleaning and polishing.
What are the benefits of a full-flow seacock?
A full-flow design ensures an unobstructed passage for water, maximizing efficiency for critical systems like engine cooling or raw water intakes, and minimizing the risk of blockages compared to restricted port designs.
Can this seacock be used above or below the waterline?
Yes, this Forespar Marelon seacock and through-hull assembly is specifically designed and approved for installation both above and below the vessel's static waterline, providing versatile application.
What standards does this Forespar seacock exceed?
This Forespar Marelon seacock assembly significantly exceeds the requirements of ABYC (American Boat and Yacht Council) H-27 standards for marine thru-hull fittings and seacocks.
What is included in the Forespar Marelon Full-Flow Seacock & 1-1/4" Mushroom Through-Hull package?
The package includes the integrated Marelon seacock valve and the 1-1/4" mushroom head through-hull fitting with buttress threading, as well as an emergency handle cap thru-hull plug for added safety.
