TL33 3/8" SAE Thread Hydraulic Quick Connect Coupler Set (1/4" Body, ISO 5675)

The TL33 is a heavy-duty, industrial-grade hydraulic coupler set designed for compact agricultural equipment and attachments. Engineered to exceed ISO 5675 standards, these 1/4" body couplers provide a reliable, high-pressure connection for a variety of compact tractors and skid steer implements.

🗸 Heavy-Duty Industrial Rating: Built for durability in rugged conditions, these couplers are rated for over 5100 PSI, ensuring exceptional performance under high-pressure demands.

🗸 Universal Ag-Style Compatibility: Designed to interface seamlessly with any standard 1/4" body Ag-style (poppet) hydraulic port, making it a direct fit for equipment from major brands including Bobcat, John Deere, CAT, Kubota, New Holland, and more.

🗸 Precision Locking Mechanism: Features a push-connect locking sleeve with heavy knurling for a secure, non-slip grip, even when working in demanding field conditions or wearing gloves.

🗸 Advanced O-Ring Boss (ORB) Connection: The 3/8" SAE (ORB) thread design ensures a superior, vibration-resistant seal that allows for repeated connection and disconnection without compromising integrity.

🗸 Corrosion Resistance: Finished with robust trivalent zinc plating to provide a long-lasting barrier against rust, moisture, and environmental exposure.

Specifications

Q: Are these "Flat Face" or "Poppet" style couplers?

A: These are AG-Style Poppet (Ball-Detent) couplers. They use a spring-loaded poppet valve, which is the industry standard for traditional agricultural tractors and many compact equipment attachments.

Q: What is the benefit of the SAE (ORB) thread?

A: The O-Ring Boss (ORB) thread is a specialized hydraulic fitting that features an O-ring on the male end. When tightened into a matching port, this O-ring provides a highly effective, leak-free seal that is much more resistant to vibration and thermal cycling than standard NPT tapered threads.

Q: Can these be used on a Flat Face (ISO 16028) system?

A: No. Ag-Style (ISO 5675) and Flat Face (ISO 16028) couplers are not interchangeable. You must verify that your machine’s existing ports match the Ag-style poppet interface.

Q: Why is the 1/4" body size significant?

A: The 1/4" body size is typically found on smaller hydraulic circuits, such as low-flow auxiliary lines, pilot controls, or compact implements. It is important to match the body size exactly; attempting to connect a 1/4" coupler to a 1/2" port will not result in a secure or functional connection.
