TL86 3/4"(#12) SAE Male Flat Face Connect Under Pressure Hydraulic Quick Coupler

TL86 1/2" Body SAE Male Flat Face "Connect-Under-Pressure" Hydraulic Quick Coupler

The TL86 is a heavy-duty, male flat-face coupler designed for high-performance hydraulic systems. Engineered to resolve the frequent issue of trapped residual pressure in hydraulic lines, this coupler features an advanced internal relief valve. It is an essential component for operators who require the ability to connect attachments quickly, even when lines have been pressurized by thermal expansion or system heat.

🗸 Connect-Under-Pressure Technology: Integrated internal valve allows you to push-to-connect even against trapped residual pressure, significantly reducing downtime when swapping implements.

🗸 High-Pressure Performance: Rated for over 5076 PSI, this coupler is built to withstand the demanding load cycles of professional skid steers and compact loaders.

🗸 Universal ISO 16028 Compatibility: Designed to interface perfectly with any standard 1/2" body ISO 16028 Flat Face hydraulic port, making it a drop-in replacement for major brands like Bobcat, John Deere, CAT, and more.

🗸 Contamination & Fluid Management: The Flat Face design allows for easy cleaning, preventing grit from entering your hydraulic lines. Furthermore, the design minimizes fluid loss to virtually zero during disconnection.

🗸 Industrial Durability: Constructed from high-strength steel with trivalent zinc plating to resist corrosion, even in harsh agricultural or construction environments.

🗸 Ergonomic & Secure: Equipped with heavy knurling on the locking sleeve to ensure a secure grip, even when working with wet, muddy, or oily equipment, and includes a protective dust cap.

Specifications

Q: How does the "Connect-Under-Pressure" mechanism work?

A: Standard flat-face couplers have a solid valve that must be pushed open against the full pressure of the trapped oil. The TL86 features a small, spring-loaded relief valve built into the main valve. When you start the connection, this relief valve opens first to bleed off the trapped pressure into the manifold, allowing the main valve to move freely and the locking sleeve to engage.

Q: Can I use the TL86 on a circuit that does not have trapped pressure?

A: Yes. The TL86 functions exactly like a standard flat-face coupler under normal conditions. The pressure-relief feature is an added benefit that only engages when it detects trapped pressure during the connection process.

Q: How do I identify if my machine is using a 3/4" (#12) SAE thread?

A: You can identify this by measuring the threads of your existing hose fitting. A 3/4" SAE (Dash -12) fitting has an outside diameter of approximately 1.06 inches and an inner diameter of approximately 0.98 inches.

Q: Do I need to replace the female side as well?

A: While the TL86 is fully compatible with your existing standard female flat-face couplers, many operators choose to replace the female side with a "Connect-Under-Pressure" female counterpart as well. This ensures that even if pressure is trapped on the machine side of the circuit, you still have the relief valve functionality to make the connection effortless.
