Marelon Thru Hull Fittings at Fisheries Supply


As a boat owner or marine professional, choosing the right materials for your vessel's plumbing systems is crucial for ensuring safety, reliability, and longevity. Let's look at the benefits and drawbacks of Marelon.

What Are Marelon Thru Hull Fittings?

Marelon thru-hull fittings are a type of marine-grade plumbing system designed for use above and below the waterline. These fittings are made from a proprietary formulation of polymer composite compounds, which provides a superior marine-grade product with unmatched reliability. Marelon thru hull fittings are precision molded to ensure complete freedom from corrosion and electrolysis, making them an excellent choice for boat owners seeking a durable and long-lasting solution.

Benefits of Marelon Thru Hull Fittings

Marelon thru hull fittings offer several benefits that make them an attractive option for boat owners and marine professionals.

Some of the key advantages include:
  • Zero Corrosion: Marelon's proprietary formulation ensures that the fittings are completely resistant to corrosion.
  • Zero Electrolysis: The absence of electrolysis in Marelon fittings prevents the buildup of electrical charges, which can cause damage to surrounding components.
  • Lightweight: Marelon thru hull fittings are significantly lighter than their bronze counterparts, making them easier to handle and install.
  • Strong: Marelon's composite material provides exceptional strength, ensuring that the fittings can withstand the rigors of marine environments.

Drawbacks of Marelon Fittings

Some drawbacks include potential brittleness in extreme temperatures and limitations in high-pressure applications compared to metal fittings. Additionally, improper installation or maintenance could lead to leaks or failures over time.

When buying Forespar Marelon thru hull fittings, you can consider things like:
Threads: Male threaded Marelon fittings will not work in female tapered threads, so knowing the threads of the fittings is important for proper sealing and strength.
Measurement: Forespar's Marelon Comparison table shows the strength of Marelon compared to bronze, and both values are measured "Dry as Molded" (DAM).
