Compactor Hydraulic Accessories — Fittings, Hoses, Seals, Filters

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.
