Common Concerns Answered
I prefer traditional bronze for my marine hardware. Why should I consider Marelon?
While bronze has a long history in marine applications, Marelon offers demonstrably superior corrosion resistance, especially in saltwater environments. This polymer formulation will not corrode, ensuring a longer service life and reduced maintenance compared to bronze fittings that are susceptible to galvanic corrosion and dezincification.
What if my boat's existing through-hull fitting has a non-standard thread size?
This Forespar integrated system is designed for simplicity and compatibility. However, for older boats with unique through-hull dimensions, it is advisable to measure your existing fitting to ensure it matches the 1" standard mushroom head through-hull provided. Replacement of existing fittings often requires adapting the hull opening to accommodate the new component.
Is Marelon strong enough for a critical through-hull fitting?
Yes, Marelon is a high-performance polymer specifically engineered for marine applications and is extensively used by major boat manufacturers. It meets and exceeds stringent standards like ABYC H-27, demonstrating its robust mechanical strength and durability under marine conditions. The integrated design further enhances security and reliability.
Frequently Asked Questions
What is the thread size of the Forespar Marelon Full-Flow Seacock & 1" Mushroom Through-Hull?
