Description
Overview:
This replacement draw tube for AL-KO 161S and 251S Delta couplings (MPN 764 121) is the sliding inner member that runs inside the overrun coupling body on braked trailers. It forms part of the telescopic mechanism that allows the hitch to move under braking, transmitting force into the overrun damper and brake linkage so the trailer brakes apply progressively. When a draw tube is worn, bent or seized, overrun travel and braking response can be affected; replacing the tube restores smooth movement and correct operation of the coupling. This unit is intended for use specifically with AL-KO Delta-pattern overrun couplings designated 161S and 251S, widely used on plant and equipment trailers, car transporters and general-duty braked trailers. It is a direct-fit service part for the coupling housing and interfaces with the existing damper and brake actuation components. Suitable for routine maintenance or repairs where the original inner tube has suffered corrosion, impact damage or excessive play.
Key Features:
- Direct replacement inner draw tube for AL-KO 161S and 251S Delta overrun couplings
- Restores smooth telescopic travel and consistent overrun braking performance
- OEM-style geometry to seat and guide correctly within the coupling body
- Interfaces with standard AL-KO damper and brake actuation linkage
- Helps eliminate play or binding caused by a worn or damaged inner tube
- Suitable for professional fleet maintenance and trailer service workshops
Typical Applications:
Used on braked trailers fitted with AL-KO Delta 161S or 251S couplings. Typical installations include plant and construction equipment trailers, car transporters, general-duty and commercial trailers in hire, utility and fleet service. The draw tube sits inside the Delta coupling housing, linking the tow connection to the overrun damper and brake linkage to manage braking force during deceleration.
