Forespar Marelon CF251 Thru-Hull Fitting

The Forespar Marelon CF251 thru-hull fitting is a through-hull fitting for boat plumbing, used for seawater intakes, cockpit drains, bilge pump discharges, and other below-waterline and above-waterline openings. It is made of Marelon, Forespar's glass-reinforced composite. The mushroom head sits nearly flush against the hull. The fitting is supplied with a matching nut.

Key Features:

• Marelon construction: glass-reinforced composite that does not corrode or electrolyze like metal fittings
• Mushroom head design: a low-profile, streamlined head that sits close to the hull exterior
• Nut included: a matching nut for securing the fitting from inside the hull
• Strong and durable: resists impact, UV exposure, and marine chemicals
• No bonding required: as a non-metallic fitting, it does not need electrical bonding

Marelon fittings are a long-lasting choice for boat owners and installers replacing aging metal through-hulls or adding new plumbing runs. They are used in sailboats, powerboats, and other marine applications. Choose the variant that matches your plumbing requirements.
