Product Description
TL28 #12 JIC Thread High Flow Flat Face Hydraulic Quick Connect Coupler Set (5/8" Body Bulkhead)
The TL28 is an industrial-strength, high-flow flat-face coupler set engineered specifically for heavy-duty older Bobcat skid steers and high-performance attachments. Featuring a 5/8" body size and a #12 JIC (#12 / 3/4") bulkhead thread connection, this set is built to handle maximum hydraulic fluid volume without restriction, ensuring your high-performance equipment runs at peak efficiency.
✓ High-Flow Engineering: Specifically designed with optimized internal pathways to reduce pressure drop, allowing the high fluid volume required by demanding attachments to pass smoothly.
✓ Bulkhead Optimized: Built with a #12 JIC bulkhead thread configuration designed for secure frame or panel mounting on older high-flow Bobcat machines.
✓ Heavy-Duty Industrial Rating: Engineered to withstand extreme operating conditions with a working pressure rating exceeding 5076 PSI.
✓ Universal ISO 16028 Compatibility: Interchanges seamlessly with any standard 5/8" body Flat Face hydraulic system.
✓ Contamination & Fluid Management: The flush-face design is easy to wipe clean, keeping dirt and debris out of your hydraulic lines. It also ensures near-zero fluid loss during disconnection.
✓ Robust Construction: Constructed from high-strength steel with a corrosion-resistant trivalent zinc plating and a heavy knurled locking sleeve for a secure, non-slip grip. Includes protective dust caps.

Frequently Asked Questions
Q: Why does this use a 5/8" body size instead of the standard 1/2"?
A: High-flow hydraulic systems on older heavy-duty loaders (like high-flow Bobcat models) require larger fluid capacities to power demanding attachments like trenchers, cold planers, or heavy brush cutters. The 5/8" body size accommodates this higher volume safely.
Q: What is a #12 JIC thread?
A: JIC (Joint Industry Council) threads utilize a 37-degree flare seat to create a metal-to-metal seal. A #12 size corresponds to a 3/4" nominal tube size (with an outer thread diameter of approximately 1.06"), commonly found on heavy-duty industrial hydraulic hoses.
Q: Are these couplers compatible with standard 1/2" couplers?
A: No. Because these feature a 5/8" body size, they will only couple to other standard 5/8" body Flat Face couplers. They will not physically connect to standard 1/2" body couplers.
Q: Do I need thread sealant for JIC fittings?
A: No. JIC fittings rely entirely on the 37-degree metal-to-metal flare seat to create the seal. Thread sealant or Teflon tape is neither necessary nor recommended on the JIC flare threads.
