Straight 1" thru hull

Product Description 

Elevate your boat’s hardware with our Premium White Mushroom‑Head Straight Thru Hull Fitting, a component that merges aesthetics, durability, and precision engineering. The classic white mushroom head ensures this fitting blends seamlessly with other thru hulls on your vessel, offering a clean, cohesive look.

Designed for rugged marine environments, this thru hull is molded from UV‑resistant Acetyl, so it resists deterioration from sun exposure and marine sealants. The plastic nut ensures a secure, watertight fit, and the design accommodates double hose clamps for added safety and peace of mind.

With extra thread length, it easily handles thicker bulkheads and transoms—ideal when installing in varied hull materials and thicknesses. Whether you're replacing worn hardware or installing new components, this thru hull fitting ensures reliable, long‑term performance.
