Designed for use with engine oil, lubricating oil, transmission fluid, and hydraulic fluids, this carbon steel quick disconnect coupling from the Eaton Aeroquip Hansen FD15 Series connects via a thread-to-connect mechanism without requiring special tools. The male-to-male configuration features a 7/16" UNC end on one side and a 5/16" ORB end on the other, with a Buna-N seal for reliable fluid compatibility across a broad temperature range starting as low as -65°F.
The Danfoss / Eaton Couplings - Code Cp meets MIL-V-81940/2-1 compliance requirements and exceeds ISO 16028 operating pressures, making it well suited for demanding industrial and mobile hydraulic applications. The Hansen sub-brand backing and Eaton Aeroquip engineering combine to deliver a complete coupling assembly rated for consistent performance in fluid transfer circuits where fast, tool-free connections are required.

Got a machine that runs on transmission fluid and needs a quick-connect setup. This a male-to-male coupling, and one end is 7/16 UNC while the other is 5/16 ORB, that right?

That's what you've got. One end is 7/16" UNC and the other is 5/16" ORB, both male. The Buna-N seal holds up well against transmission fluid along with engine oil, lubricating oil, and hydraulic fluid, so it covers a pretty wide range of common fluid types in one assembly.

Will this work okay with regular hydraulic fluid, or does it need something special?
Answer by: Customer Support on May 27, 2025, 1:57 PM
It is designed for use with engine oil, lubricating oil, transmission fluid, and hydraulic fluids, so standard hydraulic fluid should work just fine.

trying to swap out a worn quick disconnect, are the ends on this one 7/16 UNC on one side and 5/16 ORB on the other?
Answer by: Customer Support on Jul 12, 2025, 4:11 PM
It is a male-to-male complete coupling with a 7/16 inch UNC end on one side and a 5/16 inch ORB end on the other.
