Seal ring for PZ type cylinder hole

Pneumatic seals of type Pz are used for cylinders and valves.

I. Performance and Use
Pneumatic seals of type Pz are used for cylinders and valves. Double-acting cylinder seals require small groove sizes. The low-friction cylinder seal has two miniature sealing edges between which grease accumulates.

II. Material
Rubber RP or fluorine glue FKM, polyurethane TPU.
 

III. Working Situation
Working pressure: ≤ 1.2Mpa
Working temperature: -20 to 100C
Surface velocity: ≤ 1 m/s.

4. installation
This type of pneumatic piston seal of the PZ type can be inserted into the groove simply by fitting it over the piston. In order to avoid damage to the seals, the sharp edges on the piston and cylinder should be removed. In the case of no lubrication, it is important to have a complete lubrication film in the cylinder, which should be done before assembly to ensure a long working life of the seal.
 

V. Main Advantages
Small installation groove, good sealing performance;
Due to the geometry of the sealing lip, the operation is smooth;
The structure is small, so the static and dynamic friction is very low;
Suitable for dry air and oil-free air, initial lubrication during assembly to extend the work
For life has a vital role; easy to fit into the sealing groove.
