Formed packing seal generally refers to an annular seal ring formed by molding or turning from rubber, plastic, leather and metal materials.
Formed fillers are divided into two types according to their working characteristics: extruded sealing rings and lip sealing rings; according to materials, they can be divided into rubber, plastic, leather and metal. Among all kinds of extruded seals, rubber extruded seals are the most widely used, and the O-ring has the longest history and the most typical. There are many types of lip seals, including V-shaped, U-shaped, L-shaped, J-shaped and Y-shaped.
