J Perkins Brass Double Insert Coupling 5511896

The J Perkins Double Insert Coupling, part number 5511896, is a solid brass marine coupling for model boat drive systems. Its precision-machined, ribbed and splined shaft section is designed to press into flexible universal joint couplings or rubber drives, creating a link between the motor and propeller shaft. The brass construction provides corrosion resistance in wet environments, including fresh and salt water use. This insert coupling is designed to support smooth power transfer while helping reduce drivetrain movement between connected components.

Features

• Ribbed, splined insert profile helps prevent drive slip under torque.
• Solid brass construction provides corrosion resistance for marine applications.
• Designed for use with flexible universal joint couplings or rubber drives.

The double insert format provides a practical connection within a model boat drivetrain, where the motor output needs to transfer rotation to the propeller shaft. Its high-torque linking function and press-fit insert design make it suited to marine model drive assemblies using compatible coupling components.
