The filter end caps is one of the important components of the filter element, with great demand and general dimensional accuracy requirements, but the outer surface shall not have visible bumps and scratches, and the formed part shall not have defects such as crack, wrinkle and deformation. It is easy to install during assembly
The filter end caps of the filter element mainly play 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 filter end caps can effectively improve the bearing capacity of the filter material, Generally, one side of the filter end caps 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 seal the channel of the filter element. The filter end caps is made of steel plate, plastic and foamed polyurethane, in which the foamed polyurethane can be heat sealed with the filter material directly with a mold, so as to save the adhesive and sealant strip.
The materials used to produce filter end caps include galvanized steel, anti-fingerprint steel, stainless steel, and many other materials. The filter end caps have various shapes as different needs. Each of the three materials has its own advantages.
Galvanized steel is coated with zinc oxide to prevent rusting since the chemical compound takes far longer to corrode than steel. It also changes the steel’s appearance, giving it a rugged look. Galvanization makes the steel stronger and harder to scratch.
Anti-fingerprint steel is a kind of composite coating plate after fingerprint-resistant treatment on the surface of galvanized steel. Because of its special technology, the surface is smoother and it is non-toxic and environmentally friendly.
Stainless steel is material that anti-corrosion to the air, vapor, water and acid, alkali, salt, and other chemical corrosion media. The common kinds of stainless steel include 201, 304, 316, 316L, etc. It has no rust, long service life, and other characteristics.
For the specifications, there are parts sizes for reference, not all. Welcome to contact us for further discussion.

Applications
The filter element is mounted on a vehicle, engine or mechanical device. During the operation of the machine, vibration is generated, the air filter is subjected to a large stress, and the end cover can effectively improve the bearing capacity of the material. The filter end cover is generally used in the air filter, dust filter, oil filter, truck filter, and active carbon filter
