Product Description
TL88 1/2" Body Flat Face "Connect-Under-Pressure" Hydraulic Quick Coupler (Male)
The TL88 is an industrial-strength, male flat-face coupler designed to solve the common frustration of trapped residual pressure. Featuring a "Connect-Under-Pressure" valve mechanism, this coupler allows you to attach your implements even when thermal expansion has pressurized the lines, making it an essential upgrade for any operator frequently swapping attachments.
🗸 Connect-Under-Pressure Functionality: The advanced internal valve design allows you to engage the coupler even when the system has residual trapped pressure, preventing unnecessary downtime.
🗸 High-Pressure Performance: Built to withstand the rigors of heavy-duty work, the coupler is rated for pressures exceeding 5076 PSI.
🗸 Universal ISO 16028 Compatibility: While featuring an upgraded valve design, the external interface remains fully compatible with any standard 1/2" body Flat Face hydraulic system found on major brands like Bobcat, John Deere, CAT, and more.
🗸 Minimal Contamination: The Flat Face design is easy to wipe clean before connection, significantly reducing the amount of grit and debris entering your hydraulic manifold.
🗸 Spillage Prevention: Designed for environmentally conscious operation, it ensures virtually zero fluid loss during the connection or disconnection process.
🗸 Enhanced Grip: The heavy knurled locking sleeve ensures you can maintain a non-slip grip, even when the coupler is covered in hydraulic oil or when you are working in muddy conditions.

Q: What exactly is "residual pressure" and why is it a problem?
A: Hydraulic lines often trap fluid pressure due to heat expansion (e.g., sitting in direct sunlight). In standard couplers, this pressure acts like a wall, preventing the valve from opening during connection. A "Connect-Under-Pressure" coupler, like the TL88, uses a relief valve mechanism to bleed off that pressure internally as you connect, allowing the lock to engage.
Q: Can I use this with my existing standard female Flat Face couplers?
A: Yes. Because the TL88 adheres to the ISO 16028 standard, the male half will still couple perfectly with any standard female 1/2" Flat Face coupler, even those without the pressure-relief valve.
Q: Is the 3/4" NPT thread different from a 1/2" NPT?
A: Yes. The 3/4" NPT (Dash -12) thread refers to the size of the pipe thread connecting to your hose, while the 1/2" body refers to the coupler's interface size. Please ensure your existing hoses use 3/4" NPT fittings to ensure a proper match.
Q: Why is there only one coupler in this set?
A: The TL88 is sold as a specialized male-end solution often used as a replacement for high-wear attachment tips. If you need a full set (Male + Female), we can assist in identifying the matching female counterpart.
