J Perkins 1/8in Insert Coupling 3.2mm - 5511870

J Perkins 1/8in (3.2mm) Insert Coupling, part number 5511870, is a brass marine insert coupling for model boat drive systems. This precision-machined component provides a link between a motor and propeller shaft, supporting efficient power transfer through the drivetrain. Its solid brass construction is suited to use in wet environments, including exposure to fresh and salt water.

Features

• Ribbed, splined shaft section presses into flexible universal joint couplings or rubber drives.
• Solid brass construction provides corrosion resistance in marine environments.
• Helps reduce drivetrain slop between the motor output and propeller shaft.

The ribbed insert profile is designed to press securely into the coupling body, helping prevent drive slip when torque is applied. The 1/8in (3.2mm) size identifies the insert coupling's shaft dimension for suitable model boat drive system applications.
