Hobbywing Water Cool Tube 2040 For 130 Type Motor

The Hobbywing Water Cool Tube 2040 (Part No: HW30820100) is a high-efficiency aluminum cooling jacket designed specifically for 20mm diameter brushless inrunner motors, commonly referred to as 2040 or 130-size brushless motors. This is a critical upgrade for RC boat enthusiasts using the SeaKing 2040 series, as it prevents motor overheating during high-speed runs by circulating lake or pool water directly around the motor can.

Key Features:

• Precision Machined Aluminum: Constructed from lightweight, high-grade aluminum that offers excellent thermal conductivity for rapid heat transfer.
• Dual O-Ring Seal: Includes high-quality rubber O-rings that create a watertight seal against the motor casing, preventing internal water leaks while allowing for easy installation and removal.
• Integrated Water Nipples: Features two 4mm diameter inlet/outlet nozzles, compatible with standard 3x5mm or 4x6mm silicone water tubing.
• Anodized Finish: Typically finished in a vibrant Hobbywing Blue or Black anodizing to resist corrosion from freshwater and maintain a professional look.
• Compact Footprint: Designed to fit perfectly on 20mm diameter cans without interfering with motor mounts or wires in small hull configurations.

Installation Tip:

To ensure a perfect, leak-free seal, apply a very small amount of marine grease or silicone oil to the O-rings before sliding the tube onto the motor. This helps the rubber seat properly and prevents the O-rings from tearing on the edge of the motor can. For the best cooling performance, ensure your water pickup (located at the rudder or hull bottom) is free of debris to maintain high flow rates.
