The perfect choice for joining hose to Forespar ball valves and seacocks.

These tailpipes (hose adapters) are made from Forespar's high-strength, glass-reinforced, composite polymer, Marelon.
With abrasion and UV resistance comparable to bronze, and over 3/4 of the strength, Marelon's added 100% corrosion resistance makes it a "no brainer" choice for thru-hulls, valves, and other marine plumbing fittings. Among plastic fittings, Marelon is more than twice as strong as nylon, its next closest rival.
