J Perkins M6 Insert Coupling for Model Boats 5511882

The J Perkins M6 Insert Coupling, part number 5511882, is a brass insert coupling for model boat drive systems. This M6 coupling provides a link between a motor output and propeller shaft through a flexible universal joint coupling or rubber drive.

Its solid brass construction is suited to wet operating environments, including fresh and salt water exposure. The ribbed, splined shaft section is designed to press into a compatible coupling body, helping reduce drive slip and drivetrain movement when torque is applied.

Features

• Ribbed, splined insert design for pressing into flexible universal joint couplings or rubber drives
• Solid brass construction for resistance to corrosion in wet environments
• Supports smooth power transfer between motor and propeller shaft

The insert coupling is intended for model boat applications where a compact M6 threaded connection is required within the drive system. Its machined profile provides a direct mechanical connection between the coupling components.
