ZF Screw Plug

ZF Screw Plug

This is a replacement screw plug for ZF brand concrete mixer truck gearboxes. Featuring a threaded body and an internal Torx drive head, this plug is used to seal various ports on the gearbox housing, such as the oil fill, drain, or level check openings. It is a critical maintenance component for preventing oil leaks and contamination of the gearbox lubricant. This specific design with a Torx drive allows for precise torque application, reducing the risk of stripping the plug head during installation or removal.

Key Features

• Direct replacement for plugs on specific ZF mixer gearbox models
• Internal Torx drive for secure fastening and removal
• Steel construction for durability and longevity
• Threaded design for a secure seal in oil ports
