The BendPak 5323120 seal kit is the direct replacement for the BendPak lift it came off of. This is the genuine BendPak part — same fit and same working specification as the one already on your lift. Ordering the BendPak seal kit 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: 5323120
• Brand: BendPak
• Type: Genuine OEM seal kit

Hydraulic parts almost always fail by leaking. A rod seal starts weeping and the cylinder body goes wet; a hose cracks near its crimp; a fitting's o-ring flattens; the lowering valve stops seating and the lift drifts down overnight. Fluid finds the weakest seal in the loop and pushes past it. The symptom — a puddle, a slow sag, a spongy lift — tells you roughly where in the loop to look.

Not every hydraulic problem is the cylinder. A lift that lowers itself overnight usually has a lowering valve that won't seat or a leaking check, not a bad seal. A lift that jerks or won't reach full height can be a tired pump or a flow valve out of adjustment. And a hose that's cracked near the crimp will spray under pressure — a real hazard, not just a mess to mop up.

Replacing your seal kit

Swapping a hydraulic hose is mostly about relieving pressure first, catching the fluid, routing the new line so it can't rub or pinch, and bleeding the cylinders afterward. Match the new hose to the old for length, inner diameter, and end fittings. Since a hose under pressure will spray if it's cracked or loose, the full walkthrough is worth reading before you start. Full step-by-step: how to reseal a lift cylinder.

Find the right part for your lift

If you are not sure this part matches your setup, the fastest check is the visual breakdown: open our parts lookup, pick your model, and match your part against the drawing where every item is numbered. Can't read the model plate? our guide to finding your model number shows exactly where it lives on each lift type, and we are a phone call away if you would rather have us confirm it.

Signs of a hydraulic problem

Inspect every hose end to end. You're looking for cracked or brittle covers, blisters, weeping at the crimped fittings, and any spot rubbing a cable or bracket. A hose that's damp near the crimp is about to let go there. Squeeze it — a healthy hose is firm, an old one goes hard and checked or soft and mushy. Either extreme means replace it.

Parts commonly replaced at the same time

Plan the whole repair, not just the one part. Cylinders, seals, hoses, and fittings share a pressure system and a service interval, so replacing the obvious failure without the worn companions just sets up the next leak. Give us your model and serial and we will assemble the complete hydraulic kit.

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

Clean matters as much as tight in a hydraulic job — a speck of grit through a valve or seal will cost you the repair twice. Cap ports the instant a line is open, use the correct oil, bleed thoroughly, and leak-check at full pressure. Always set the lift on its locks before working underneath it.

Before you order

Get the details right up front: model, serial, hose lengths, fitting types, and power-unit voltage where it applies. If the cylinder is only weeping, a seal kit is often the better call. Order the oil you will need for the refill at the same time, and we will verify fit before anything leaves the shelf.

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.
