O-rings and packings are among the most commonly used seals and are highly practical. Movable seals specifically used for sealing pistons and pump shafts are called packings. Seals are necessary for pumps because there are parts of the pump where leakage or air ingress can occur. By choosing a suitable sealing system, the fluid can be protected, and air entry into the pump can be prevented.

Packings are made from various materials, including plastic, natural rubber, and synthetic rubber. They work by creating fluid pressure that causes the edge of the seal to adhere to the wall, enhancing the seal's performance. The usage of these seals typically starts from a single package, and multiple seals can be placed together in one groove.

O-rings are easy to install and have numerous positive features that drive their sales. Sealing packings are composed of different parts, such as gaskets, liners, and sealing caps. A crucial characteristic of liners is their softness and flexibility, allowing them to cover pores effectively without hindering the rotation and movement of the shaft. Advantages of packings include low friction, increased chemical resistance, good abrasion resistance, high thermal and heat transfer efficiency, and resistance to deformation. Packings can withstand high pressure and have additional applications in high-speed elastic bands and bearings.

Packings are mainly available in two materials: asbestos, primarily used for low temperatures, and metallic, typically used for high temperatures. Lubrication is very important in packings.
