DANFOSS / EATON Male pipe thread Sampling

Description & Features

Designed for fluid sampling in engine oil, lubricating oil, transmission fluid, and hydraulic fluid circuits, this carbon steel quick disconnect coupling features a male NPTF end on one side and a male UNF thread connection on the other. The 5/16-inch port size and Buna-N seals make it well suited for use across a range of industrial fluid systems requiring routine sampling access.

The Danfoss / Eaton Male Pipe Thread Sampling valve belongs to the Hansen FD15 Series and connects via a thread-to-connect mechanism, no special tools required. It meets MIL-V-81940/2-1 compliance and exceeds ISO 16028 operating pressure requirements. Rated for a minimum working temperature of -65°F, it performs reliably in demanding temperature environments.

Question by: Lyle C on Mar 28, 2026, 3:13 PM
got a sampling port on a hydraulic circuit, what fluids is this FD15-1000-04 meant to pull samples from?
Answer by: Customer Support on Mar 30, 2026, 6:41 AM
For routine sampling, it is meant for engine oil, lubricating oil, transmission fluid, and hydraulic fluid circuits.
Question by: Danny P on Apr 3, 2026, 9:06 PM
this thing work on transmission fluid lines, or is it only for engine oil and hydraulics?
Answer by: Customer Support on Apr 5, 2026, 9:32 AM
Transmission fluid is actually one of the listed applications for this coupling, right alongside engine oil, lubricating oil, and hydraulic fluid. The Buna-N seals and carbon steel body handle that range of fluids well, so you're good to go on that front.
