High-Quality Harsh Environments Cylindrical Cartridge Air Filter Metal End Cap

The filter end cap mainly serves to seal both ends of the filter material and support the filter material. It stamped into various shapes as needed from the steel sheet. The end cap is generally stamped into a groove on which the end face of the filter material can be placed and an adhesive can be placed, and the other side is bonded with a rubber seal to function to seal the filter material and seal the passage of the filter element.

1. For the production,  Dongjie Supplied filter end caps include filming, molding, blanking sheets, and punching. The picture of the production process is as below:

2.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 medium. The common kinds of stainless steel include 201, 304, 316, 316L, etc. It has no rust, long service life, and other characteristics.

3. For the specifications, there are some common sizes for reference, not all. Welcome to send an inquiry to discuss more details.

4. Application

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.
