Designed for very high-pressure hydraulic lines subject to pressure surges and repeated flexing, the Danfoss / Eaton Hose End (Perm) R1290 D -20 Code 61 Flg is a permanent fitting assembly suited to demanding environments including mining, construction, farming, and high-performance industrial equipment.
Constructed from carbon steel, this fitting features a flanged end (Code 61) on one side and a hose/line connection on the other, with a -16 hose dash size and a drop dimension of 2.38 inches. The permanent assembly design provides a reliable, secure connection in hydraulic systems where consistent performance under high-pressure conditions is critical. At 2.65 lb, this is a robust component built to the standards associated with the Eaton Weatherhead line, now marketed under the Danfoss Power Solutions brand.

Application
Very high pressure hydraulic lines subjected to pressure surges and fl exing. Some applications include mining, construction, farming, and high performance industrial equipment
Got a hydraulic line on a piece of heavy construction equipment that sees some pretty nasty pressure spikes. This a permanent fitting or something I'd need to swap out regular?

Permanent assembly, so once it's crimped on, it stays put. That's actually the right call for lines that take repeated pressure surges because you're not dealing with a connection that can back off or work loose over time. It's built from carbon steel, which holds up well in the kind of abuse that comes with construction equipment. The Code 61 flanged end handles the high-pressure side, and the hose connection is a -16 dash size, so make sure your hose matches that before ordering.

Trying to replace a hose end on a machine, is this one the Code 61 flanged style and what hose size is it set up for?

You are looking at a permanent hose end with a Code 61 flanged end on one side, and it’s built for a -16 hose dash size on the hose connection side.
