Overview
A hydraulic system is only as clean as its filters let it be. Contaminants that pass a worn or poorly sealed element wear pumps, valves and cylinders long before they fail outright.
Most systems filter in three places. A suction strainer protects the pump at the reservoir. A pressure-line element protects the valves and actuators downstream of the pump. A return-line element cleans the oil on its way back to the tank.
PureCore supplies replacement elements for each of them, with media chosen for the duty and dimensions and sealing surfaces checked so the element installs and seals correctly. Share the part number, the dimensions, a sample or clear photos, and we will propose a matched equivalent, or develop one from the sample where no standard equivalent exists.

How to match a part
Any one of these is enough to start. Send what you have and we will propose a matched element.
Part number
The number printed on the element or in the machine manual. The fastest way to a match.
Dimensions
Outer and inner diameter, length, thread and seal details of the old element.
Sample
Send the old element. We match it, or develop a replacement from it.
Photos
Clear photos of the element, its labels and both end caps.
