Used Tractor & Combine Harvester Hydraulic Coupler

Used Hydraulic Quick Couplers Available at TMC Bejenne

The hydraulic circuit of your tractor relies on dependable connections between each component: distributor, pump, cylinder, and hitch receivers. The used hydraulic quick coupler offered by TMC Bejenne comes from machines dismantled on our 11-hectare yard and undergoes inspection before sale. With a stock of 25,000 references constantly refreshed, you benefit from rapid supply for major brands: John Deere, Case IH, New Holland, Massey Ferguson, Fendt, and more. To complement your supply of used agricultural equipment, also explore our ranges of hydraulic distributors, hydraulic pumps, multi-couplers, and hydraulic cylinders.

Male-Female Push Pull Hydraulic Couplers: Types and Uses

The push pull coupler is the most common standard found on agricultural tractors. The mechanical connection is made by simply pushing the male end into the female end; disconnection happens by pulling. This type generally includes a check valve that reduces fluid leakage during disconnection and protects the circuit. Models with ball-locking maintain the mechanical connection even under strong vibrations, making them suitable for rough terrain work. Certain push pull couplers also allow disconnection under residual pressure, useful when the circuit remains pressurized at rest. TMC Bejenne stocks male and female push pull couplers in various sizes according to your circuit flow.

Valve and Screw-Type Hydraulic Couplers: When to Choose Them?

Two major types complement the used agricultural equipment offer at TMC Bejenne:

• Valve coupler: The integrated valve prevents fluid loss upon disconnection. Standard on most tractors, compatible with double-acting distributors.
• Screw coupler: Threaded for enhanced sealing under high pressure. Used on precision equipment, fixed installations, or high-demand circuits.
• Push pull couplers by size: Available in several bore sizes (1/2 inch, 3/4 inch, etc.) to match the flow and pressure of each circuit.
• Ball locking: A safety mechanism that maintains mechanical connection under load. Recommended for heavy mounted equipment.
• Disconnection under residual pressure: Check compatibility with your distributor before installation, as some models require it.

Hydraulic Coupler Operation and Troubleshooting

A leaking hydraulic coupler, one that fails to connect or disconnects under pressure, typically indicates a worn valve ball, an aging O-ring seal, or a cracked coupling body. Troubleshooting begins with releasing residual pressure in the circuit before handling: forced disconnection under pressure can cause fluid ejection or damage the circuit. In most cases, replacing the entire coupler is quicker and more cost-effective than repairing individual parts.
