Heavy Equipment Hydraulic Parts: Cylinders, Hoses, Pumps, and More

Find durable hydraulic parts for excavators and heavy machinery, organized for fast selection and uptime-critical repairs. This category includes pumps, cylinders, cylinder assemblies, seal kits, barrels and pistons, hoses, flanges, cartridges, wiper rods, U‑cup seals, and excavator couplings covering core power transmission and motion-control needs across mobile equipment. Shop by part type to match OEM specs, restore pressure, stop leaks, and keep travel, lift, and swing functions operating at peak efficiency.

Designed for construction, agriculture, mining, and industrial fleets, these parts support quick turnaround and long-term reliability when systems show symptoms like slow travel, creeping loads, overheating fluid, or pressure loss.

Propel Parts carries a full range of hydraulic components including pumps, cylinders, cylinder assemblies, cylinder seal kits, barrels and pistons, hoses, flanges, cartridges, wiper rods, U-cup cylinder seals, and excavator couplings. This lets technicians source both complete replacements and component-level rebuild parts in one place.

Common symptoms include external oil leaks, spongy or drifting cylinders, loss of lifting power, slow travel or swing, overheating fluid, and contamination in the reservoir. Seal kits, U-cups, and wipers can often restore performance if the barrel and rod are still within spec; otherwise consider a cylinder assembly or component replacements.

Yes. Beyond complete pumps and cylinders, our inventory includes barrels, pistons, cartridges, flanges, hoses, wiper rods, and U-cup seals ideal for cost-effective, component-level repairs when the core unit is serviceable.

Use the correct seal materials and sizes, replace wipers during every reseal, keep hoses within pressure and bend specs, flush lines after failures, and maintain clean fluid. Proper torque on flanges and fittings and timely replacement of worn hoses help avoid repeat downtime.

Hoses are available with common diameters and end configurations. Verify thread type, seat/flare style, and length. Matching fittings and flanges are listed so the line can be built or replaced without guesswork.
