90° Marine Bilge Pump Drain Fitting – Nylon Thru-Hull Connector

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.
