Marine-Ablauf

Why Boaters Choose This Drain Outlet

• Compact 46mm outlet profile – Smaller footprint than standard fittings means a cleaner, more professional-looking installation that doesn't snag lines or gear.
• Thickened 6.5mm outlet wall – Reinforced walls resist cracking, impact, and deformation — far more durable than thin-walled alternatives that fail under stress.
• Arc-sloped face design – The curved outlet face reduces water resistance and sits flush against the hull contour, minimizing drag and improving hydrodynamic performance.
• Flat wrench-access recess (预留平面) – A built-in flat surface lets you grip and tighten with a standard wrench without damaging threads — no more stripped fittings or frustrating installs.
• ABS material – corrosion-proof & non-yellowing – Marine-grade ABS resists saltwater, UV rays, and chemical exposure. Won't yellow, crack, or degrade over time like cheaper plastics.
• Available in Black & White – Match your hull color for a seamless, factory-finish look.

Solves These Common Problems

• ❌ Drain fittings that stick out and create drag → ✅ Low-profile arc-slope design hugs the hull
• ❌ Cracked or brittle fittings after one season → ✅ Thickened 6.5mm ABS walls built for longevity
• ❌ Stripped threads during installation → ✅ Wrench-flat recess for secure, damage-free tightening
• ❌ Yellowing plastic that looks cheap → ✅ UV-stable ABS stays clean and professional

Applications
