TL87 1/2"(#8) SAE Male Flat Face Connect Under Pressure Hydraulic Quick Coupler

TL87 1/2" Body SAE Male Flat Face "Connect-Under-Pressure" Hydraulic Quick Coupler

The TL87 is a heavy-duty, male flat-face coupler engineered for operators who frequently swap attachments and need to overcome trapped residual pressure. Designed to exceed ISO 16028 standards, this component allows for secure connection even when high-pressure circuits have accumulated heat-induced pressure, effectively eliminating the common struggle of connecting hydraulic lines under load.

🗸 Connect-Under-Pressure Functionality: The integrated internal relief valve allows the male tip to be connected even when residual heat expansion has trapped pressure in the hydraulic lines, saving significant time on the job site.

🗸 High-Pressure Performance: Rated for over 5076 PSI, this coupler is built to handle the intense demands of modern skid steer hydraulic systems.

🗸 Universal ISO 16028 Compatibility: While featuring an advanced pressure-relief valve, the interface remains fully compatible with any standard 1/2" body Flat Face hydraulic system.

🗸 Minimal Contamination: The Flat Face design is engineered to prevent debris ingress; the flush surface is incredibly easy to wipe clean before connecting, keeping your hydraulic manifold pristine.

🗸 Spillage Prevention: Designed for environmentally responsible performance, it ensures virtually zero fluid loss during connection and disconnection.

🗸 Enhanced Grip & Protection: The heavy knurled locking sleeve provides a non-slip grip, even with gloves, and the included dust cap shields the coupler face from the elements when not in use.

Specifications

Q: Why is "Connect-Under-Pressure" so important for my skid steer?

A: Hydraulic fluid expands as it heats up (like when a machine sits in the sun). This creates "residual pressure" in the lines that pushes back against the poppet valve in standard couplers, making it physically impossible to lock the coupler into place. The TL87 has a dedicated valve to relieve this pressure during the connection stroke, allowing it to snap into place easily.

Q: Can I use the TL87 with my existing standard female couplers?

A: Yes. The TL87 is a male coupler designed to mate with any standard 1/2" body ISO 16028 female coupler. You do not need to replace your entire manifold system to utilize the benefits of this coupler on your attachment lines.

Q: What does the "#8" designation in the thread size mean?

A: The #8 SAE (Society of Automotive Engineers) designation, also known as -08, refers to the thread diameter (3/4"-16 UNF). This is the standard fitting size for the hose end, while the 1/2" body size is the interface that connects to your machine.

Q: How do I maintain this coupler to ensure the Connect-Under-Pressure valve stays working?

A: The most important maintenance step is keeping the face clean. Even with a relief valve, grit can interfere with the O-ring seals. Always use the included dust cap when the attachment is stored, and wipe the face with a clean rag before every connection.
