J Perkins Brass 6.0mm Insert Coupling 5511868

The J Perkins 6.0mm Insert Coupling, part number 5511868, is a brass marine insert coupling suggested for model boat drive systems. It provides a link between a motor and propeller shaft, helping transfer drive through the drivetrain.

Precision-machined from solid brass, this coupling has a ribbed, splined shaft section designed to press securely into flexible universal joint couplings or rubber drives. The profile helps resist drive slip under torque, while the brass construction is suited to use around fresh and salt water.

Features

• 6.0mm insert coupling for model boat drive systems
• Ribbed, splined shaft section for secure insertion into compatible flexible universal joint couplings or rubber drives
• Solid brass construction for corrosion resistance in wet environments

The coupling is designed to help reduce drivetrain movement between the motor output and propeller shaft, supporting smooth power transfer in a marine model setup.
