Removes particle contaminants from the hydraulic fluidProvides linear path for low flow restrictionReduces corrosion and abrasionHighly durable and reliableEasy installation with snug fitWix Spin-On Hydraulic Filters are designed to remove particle contaminants from the hydraulic fluid. They are made of pleated paper which filters the contaminants down to microscopic size and provide a linear path for low flow restriction. These filters reduce corrosion and abrasion of hydraulic components and are highly durable and reliable.
