TL63 1/2" Body 4BD4FH Cartridge Male Flat Face Coupler

The TL63 is a high-performance, cartridge-style male flat-face coupler designed specifically for machines equipped with the 4BD4FH manifold block system. Engineered for demanding environments, this coupler ensures secure, leak-free connection for skid steer and excavator attachments while protecting your system from contamination with its spill-minimizing flat-face design.

🗸 Precision Manifold Fit: Specifically engineered for the 4BD4FH manifold with a 48mm thread diameter, ensuring a direct and secure installation.

🗸 Connect-Under-Pressure Functionality: Equipped with an internal mechanism that allows you to connect attachments even when residual heat has trapped pressure in the hydraulic lines, saving time and frustration on the job site.

🗸 Industrial Durability: Constructed from zinc-plated steel and rated for a maximum working pressure of 350 bar (35 MPa), capable of handling the most rigorous agricultural and construction tasks.

🗸 ISO 16028 Compliance: Fully interchangeable with any standard ISO 16028 flat-face coupler, providing wide compatibility with various attachments and machine configurations.

🗸 Low-Profile Cartridge Design: The thread-in design reduces the exterior profile of the coupler, effectively minimizing side-loading and protecting the coupler from accidental impact damage.

🗸 Clean Hydraulic Operation: The flat-face architecture minimizes hydraulic fluid spillage during disconnection (0.02 ml), keeping your machine clean and preventing environmental hazards.

Specifications

Q: You mentioned there are two different thread sizes for this manifold type. How do I make sure I get the right one?

A: Because there are variations in the 4BD4FH manifold system, we strongly recommend measuring the outside diameter (OD) of your current coupler’s thread. This TL63 model has a 48mm OD thread. If your measurement differs significantly, you may require the alternative size. Additionally, comparing the style of the o-rings on your existing part to the images provided on your listing is a great way to visually verify the match.

Q: Is this a standard hose-end coupler or a cartridge coupler?

A: This is a cartridge-style coupler. It is designed to be threaded directly into the 4BD4FH manifold block on your machine, not onto the end of a flexible hydraulic hose.

Q: Can I use the TL63 to replace a standard poppet-style coupler?

A: No. Flat-face couplers (ISO 16028) and poppet-style couplers are not interchangeable. You must verify that your current manifold system utilizes the flat-face design to ensure proper fitment and fluid flow.

Q: Does "Connect-Under-Pressure" mean I can connect it while the machine is running at full flow?

A: No. "Connect-Under-Pressure" refers to the ability to overcome residual pressure trapped in a disconnected attachment hose (caused by sun-heated oil expansion). It does not mean you can connect it to a pressurized, live hydraulic circuit. Always ensure the machine is off and the system is properly depressurized before attempting to connect or disconnect hydraulic lines.
