Stop bilge water from backing up into your boat — this 90° nylon thru-hull drain fitting creates a watertight, corrosion-proof connection between your bilge pump hose and hull, preventing leaks, odors, and water damage at the exit point. Whether you're replacing a cracked fitting or installing a new bilge pump system, this compact 90-degree elbow delivers a secure, professional-grade seal that lasts season after season.

Product details

Why This Fitting Solves Real Problems

  • Eliminates awkward hose routing: The 90° elbow angle lets you route bilge pump hose cleanly along the hull without kinking or bending — a common cause of restricted flow and pump burnout.
  • Watertight thru-hull seal: Double-flange design with integrated nut clamps firmly against the hull interior and exterior, preventing water ingress even under wave pressure.
  • Corrosion-resistant nylon: Premium glass-filled nylon construction resists saltwater, UV exposure, fuel, and bilge chemicals — outlasting metal fittings in harsh marine environments.
  • Universal hose barb: 19mm (3/4") barbed inlet fits standard bilge pump discharge hoses for easy, tool-free connection.
  • Compact footprint: At just 21mm wide and 19mm tall, it installs in tight bilge spaces where larger fittings won't fit.
