Product Description
TL91-M 1" NPT Thread 1" Body Flat Face Hydraulic Quick Disconnect Coupler (Male)
The TL91-M is an industrial-grade, high-capacity flat face hydraulic coupler engineered for the most demanding heavy machinery applications. Designed to meet and exceed the ISO 16028 standard, this coupler provides a robust, leak-resistant connection capable of handling high-pressure systems while minimizing fluid loss and system contamination.
🗸 Heavy-Duty Industrial Rating: Built for extreme environments, this coupler is rated for over 5076 PSI to ensure peak performance under high-pressure loads.
🗸 High-Capacity Design: Featuring a 1" body size, this coupler is optimized for heavy equipment and high-flow attachments where maximum oil delivery is required.
🗸 ISO 16028 Compliance: Fully interchangeable with any standard 1" body Flat Face quick disconnect system, ensuring broad compatibility across heavy machinery fleets.
🗸 Precision Locking Mechanism: The push-connect sleeve is equipped with heavy knurling to provide a secure, non-slip grip, allowing for fast attachment changes even when the operator is wearing heavy safety gloves.
🗸 Advanced Contamination Control: The Flat Face design allows for easy cleaning of the interface before connection, effectively preventing dirt and debris from entering your hydraulic lines.
🗸 Integrated Protection: Includes a high-quality protective dust cap to shield the coupler face from debris and the elements when not in use.

Q: Why is a 1" body size used instead of the more common 1/2"?
A: A 1" body size is required for high-flow hydraulic systems found on larger heavy machinery. Using an undersized coupler would create significant backpressure, restrict performance, and potentially overheat your hydraulic system.
Q: Is the Flat Face design better than traditional poppet-style (AG) couplers?
A: Flat Face (ISO 16028) couplers are superior in applications where keeping the system clean is critical. Unlike poppet valves, which trap dirt in the recess, the flush face is easy to wipe clean, significantly reducing the risk of internal component failure due to contamination.
Q: Can this be connected under pressure?
A: Standard ISO 16028 couplers are not designed to be connected under full system pressure. Attempting to do so can damage the internal seals. Always ensure your hydraulic circuit is fully depressurized before making or breaking a connection.
Q: How do I know if this is the correct thread size for my hose?
A: The 1" NPT thread is standard for large-bore hydraulic hoses. If you are unsure, you can measure the inside diameter of your hose fitting. A 1" NPT fitting will have an approximate thread inner diameter of 1.23".
