Forespar Marelon Pipe to Hose Adapters
Forespar Marelon Pipe to Hose Adapters: The Corrosion-Free Connection
When it comes to below-deck marine plumbing, the weakest link is often where rigid pipe meets flexible hose. Forespar has engineered a purpose-built solution: their line of Marelon Pipe to Hose Adapters—sometimes called tailpipes—that create secure, leak-resistant transitions between threaded pipe and hose lines throughout a vessel's plumbing system.
What Is Marelon®?
These hose adapters are made from Forespar's high-strength, glass-reinforced composite polymer, Marelon®. Unlike traditional bronze or brass fittings, Forespar's Marelon® polymer delivers zero corrosion, zero electrolysis, light weight, and strength—all critical qualities in the harsh saltwater marine environment. With abrasion and UV resistance comparable to bronze, and over three-quarters of the strength, Marelon's 100% corrosion resistance makes it an ideal choice for sailors and powerboaters who want plumbing that simply won't fail due to oxidation or galvanic action.
Designed to Integrate with Forespar's Marine Plumbing Ecosystem
Forespar Marelon Pipe to Hose Adapters, also known as Tailpipes, are an ideal choice for joining hose lines to Forespar Ball Valves and Seacocks. This makes them a natural complement to a complete Forespar Marelon plumbing installation, ensuring consistent material compatibility from thru-hull to hose throughout the boat.
The adapters are available in both male and female threaded configurations and span a wide range of sizes to match common marine hose and pipe dimensions. Available configurations include options such as male thread ½" to 5/8" barb, female thread 1½" to 1-1/8" barb, and male thread 1" to 1-1/8" barb, among others—covering the most common transitions found on sailboats and powerboats alike. NPT tapered pipe thread variants ensure a tight, reliable seal when used with Teflon tape or plumber's putty, as recommended by Forespar for their threaded fittings.
