About

Description

Ensure a watertight, durable hull penetration for your SeaWater Pro modular watermaker with our 1/2" Thru-Hull Fitting. This essential marine-grade component provides a secure channel for intake or discharge lines, safeguarding your vessel against leaks and corrosion while optimizing system performance.

Key Features

  • Marine-Grade Construction: Made from high-quality 316 stainless steel (or UV-stable nylon in the plastic variant) to resist corrosion, pitting, and biofouling in saltwater environments.

  • Precision Machining: Smooth, burr-free interior bore minimizes turbulence and maximizes flow efficiency through the hull.

  • Leak-Proof Design: Includes a high-pressure O-ring gasket and backing nut to create a reliable, compression-style seal.

  • Low-Profile Profile: Compact flange sits flush to the hull for a clean installation that won’t catch lines or impede movement.

  • Easy Installation & Maintenance: Threaded body and large knurled backing nut allow hand-tightening; service the O-ring without removing your watermaker.

Specifications

  • Bore Size: 1/2" (13 mm) ID through-hull diameter

  • Material Options: 316 stainless steel or UV-stabilized marine nylon

  • Pressure Rating: Suitable for up to 150 PSI (watermaker feed/discharge)

  • Temperature Range: –40 °F to 250 °F (–40 °C to 120 °C)

  • Seal: EPDM O-ring gasket included

  • Flange OD: 1 7/8" (48 mm)

Applications

  • Intake or discharge lines on SeaWater Pro modular and portable watermaker systems

  • General-purpose low-pressure thru-hull for freshwater washdowns, deck drains, or wash pumps

  • Retrofit installations on yachts, liveaboards, and commercial vessels
