Compactor Hydraulic Accessories — Fittings, Hoses, Seals, Filters

Replacement hydraulic accessories for industrial trash compactors — fittings, hoses, seals, filters, gauges, and reservoir components. The small parts that make every hydraulic system work and fail predictably enough to keep in standing stock.

What this page covers

Hydraulic accessories are everything that isn't a pump, valve, or cylinder — but every accessory matters. A leaking fitting drains an entire reservoir overnight. An abraded hose fails at the worst possible moment. A clogged filter destroys a pump. Stocking the most-replaced accessories is the cheapest hydraulic system maintenance you can do.

PRT stocks the standard industrial fittings (NPT, JIC, SAE O-ring), hose assemblies in the most common sizes, cylinder and pump seal kits, return-line and suction filters, hydraulic gauges, and reservoir hardware (sight gauges, breathers, fill caps, drain valves). Most ship same day.

How to choose

For fittings, match by thread type (NPT, JIC, SAE O-ring), thread size, and hose connection. For hoses, match by inner diameter, working pressure, length, and end fittings. For seals, match by cylinder or pump model and the OEM seal kit number.

When replacing seals on a cylinder or pump, also replace the wiper seal and any sealing surfaces that show wear. Re-using a single worn component re-introduces the contamination that killed the system in the first place.

Hydraulic accessory categories

  • Hydraulic FittingsNPT, JIC, SAE O-ring fittings in standard thread sizes.
  • Hydraulic HosesStandard sizes from 1/4 inch to 1 inch ID, 2000-5000 PSI working pressure.
  • Cylinder Seal KitsPiston, rod, wiper, and O-ring seals for ram and tailgate cylinders.
  • Pump Seal KitsShaft seals, body seals, and O-rings for pump rebuilds.
  • Hydraulic FiltersSuction strainers, return-line filters, and pressure-line filters.
  • Hydraulic Gauges0-3000 PSI and 0-5000 PSI pressure gauges for diagnostics.
  • Reservoir HardwareSight gauges, breathers, fill caps, drain valves.

Frequently asked questions

How often should I change hydraulic filters on a compactor?

Replace the return-line filter every 1,000 hours or annually, whichever comes first. Replace the suction strainer with every oil change. Filters are cheap; pumps and valves are not.

What hydraulic hose pressure rating do I need for a compactor?

Match the hose's working pressure to the system's operating pressure with a 4:1 safety margin. Most compactors run 2,000-2,500 PSI, so a 2-wire braid hose rated to 5,000 PSI working pressure is the right choice.

Can I rebuild a hydraulic cylinder with PRT seal kits?

Yes. PRT seal kits include piston seals, rod seals, wiper seals, and O-rings — everything needed to rebuild the most common compactor cylinders. Provide the cylinder model and bore/rod dimensions.

Are PRT hydraulic fittings interchangeable with Parker, Eaton, and Aeroquip?

Yes. PRT fittings follow industry-standard thread specs (NPT, JIC, SAE O-ring). They're dimensionally interchangeable with major-brand fittings — specify by thread type and size, not brand.
