Abstract
A magnetic particle filter for a hydraulic control line is disclosed. A filter array is positioned to surround a portion of the hydraulic control line and includes alternating magnets and spacers having different interior diameters forming a ribbed interior surface. The corners between the spacers and magnets trap particles, magnetic and non-magnetic, thus removing them from the hydraulic control line.
