The end cover of the filter element mainly plays the role of sealing both ends of the filter material and supporting the filter material. The steel plate is mainly pressed into various shapes as required. The filter element is installed on the vehicle and engine, which will produce vibration during mechanical operation, and the air filter will bear great stress. The end cover can effectively improve the bearing capacity of the filter material, Generally, one side of the end cover is stamped into a groove that can place the end face of the filter material and the adhesive, and the other side is bonded with a rubber seal to seal the filter material and the channel of the filter element.
There are parts of specifications of filter caps we made for clients before for your reference. If you need other shapes, we could make customization.
