The Rotary FC5225-16X hydraulic hose is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7516-31A, it is the genuine Rotary part — same part number, same fit, and same working specification as the one already on your lift. Ordering the Rotary hydraulic hose from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.
Specifications
- Part number: ALS-7516-31A
- Brand: Rotary
- Type: Genuine OEM hydraulic hose
Hydraulic parts fit by the numbers, and the numbers are unforgiving. A cylinder has to match working length and port type; a hose is spec'd by inner diameter, pressure rating, and end fittings; a power unit lives or dies on voltage. Even seal kits differ by who built the cylinder — the same lift model can carry two cylinder brands with different seal profiles. Order to the actual part, not the lift name.
No hydraulic part works alone. A cylinder is only as good as the fluid feeding it, the fluid is only as clean as the reservoir and filter keep it, and a fresh seal kit won't hold in a barrel that's already scored. That's why a leak is worth diagnosing as a system: replace the weeping part, but check the fluid, the fittings, and the bore before you call it fixed.

Replacing your hydraulic hose
A lowering or flow valve issue — a lift that drifts down or won't reach full height — is often fixed at the valve rather than the cylinder, but it takes a methodical check to be sure. Isolate whether the leak is internal or external, then service or replace the valve and confirm the lift holds height afterward. The step-by-step guide lays out how to trace it.

Find the right part for your lift
Not certain this is the exact part your lift needs? Start with your lift's model and serial off the data plate, then open our Rotary parts lookup to see the visual parts breakdown for your model — the exploded drawing with every part numbered and priced. If your plate is missing or unreadable, our guide to finding your model number walks through where to find it, or send us a photo and we will identify the lift for you.
Signs of a hydraulic problem
For a seal kit specifically, the decision is made inside the barrel. Before you order seals, confirm the bore isn't scored and the rod isn't pitted where the seal rides — new seals won't hold in a damaged cylinder. Shine a light down the barrel; smooth and shiny is good, scratched or rust-pitted means the cylinder itself needs replacing, not just seals.
Parts commonly replaced at the same time
One trip up, one refill, one bleed: order the companion hydraulic parts with this one. A seal kit alongside a cylinder, a fresh hose, and the correct oil turn a partial fix into a finished job. Tell us what lift you have and we will build the kit so nothing is left to fail next.
Hydraulic fluid
Fluid matters on any hydraulic repair: most lifts take an ISO-32 hydraulic oil, though a number of older ones spec Dexron ATF. Match whatever is already in the reservoir rather than mixing types, and top off to the level your manual specifies after bleeding — capacities differ from model to model.
Safety notes
Pressure and cleanliness are the two rules. Bleed the system completely so there is no air to compress, keep contamination out of every open port, and prove the lift holds at full height with no drift before it sees a vehicle. If you are not certain the bleed is complete, do it again — this is not the place to guess.
Before you order
Ordering tip: hydraulic parts are matched to the lift's pressure and geometry, so read the model and serial off the plate and, for hoses and cylinders, have the old part's dimensions. Plan to replace the oil and bleed the system as part of the job, and add a seal kit if you are opening the cylinder anyway.
Ordering the right revision
Before this goes in the cart, grab two things off your lift: the model number and the serial number, both on the manufacturer's plate. The serial matters more than most people expect — lift makers revise components between production runs without renaming the lift, and the run your serial falls in determines which revision of this part is correct.
If you are working from a failed part rather than a plate, measure what you have and photograph how it mounts. Send that to us along with the lift brand, and we will check it against the same parts breakdowns our own techs use in the field before you commit to the order.
