Knowledge points Structure of PH444 Oil Filter 1.Outer Shell: The outer shell is made of a durable material that protects the filter's internal components and provides structural integrity. 2.Canister: The canister is the main body of the filter and holds the filtration media and internal components. It is designed to withstand the flow and pressure of the oil passing through. 3.Filtration Media: The filtration media is the critical component responsible for capturing contaminants in the oil. It is typically made of high-quality materials like cellulose or synthetic fibers that trap and retain particles of various sizes. 4.Anti-Drainback Valve: The anti-drainback valve prevents residual oil from draining back into the engine when it is turned off. It maintains oil pressure and ensures immediate lubrication when the engine is started. 5.Bypass Valve (if applicable): Some oil filters, including the PH444, feature a bypass valve that allows oil to bypass the filter if it becomes clogged or the oil flow is restricted. This provides continuous oil flow to the engine during such situations to prevent engine damage. Overall, the PH444 Oil Filter is designed with a robust structure and high-quality components to effectively filter and protect the engine by removing contaminants and maintaining proper oil flow.   PH444 Attributes: Outer Diameter 108 mm (4.25 inch) Thread Size 7/8-16 UN Length 205 mm (8.07 inch) Gasket OD 72 mm (2.83 inch) Gasket ID 63 mm (2.48 inch)   PH444 OEM Cross Reference: Baldwin BT124 Case IH A62423 A59110 Cyclone PM461 Donladson P559130 P550714 Fleetguard LF790 GMC 25011133 Hifi SO 790 Komatsu L790PP Kox FO043 Orenstein & Koppel 1448774 Perry PL368 Volvo 48044069 4804406 8010773 White 40-0000406 Wix 51458   PH444 Picture show
