Removes particle contaminants from the hydraulic fluidProvides linear path for low flow restrictionReduces corrosion and abrasionHighly durable and reliableEasy installation with snug fitWix Coolant Spin-On Filters are designed to remove the particulate contaminants from the cooling system. 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.
