Filter with molded end cap

摘要

A filtering element includes a circumferentially extending filter media having a pair of opposite ends. An end cap assembly closes the ends of the filtering media and consists of an annular cup-shaped member defining a circumferentially extending trough. A circumferentially extending band of sealant is dispensed into the trough. The media and the centertube, which supports the inner diameter of the media, is installed in the sealant within the trough. The sealant may be either Plastisol or a photo-initiating polymer. The end cap can be made transparent to ultraviolet light, so that the photo-initiated polymer can be cured by transmitting ultraviolet light through the end cap.
