Pneumatic piston seal type PPD

PPD type is a small double-acting piston seal. Compared with O-ring, it has better friction performance and unique cross-sectional design to avoid damage due to twisting. It is used for standard cylinders, small diameter cylinders and thin cylinders.

Working range:

Working pressure: ≤1.0MPa;

Working temperature: -20℃~+80℃

Surface speed: ≤1m/s

Medium: Air, oil-lubricated and dry air, oil-free air (initial lubrication during assembly)

Installation: This type of pneumatic seal can be easily placed on the piston and installed in the groove. To avoid damage to the seal, take measures to avoid sharp edges during installation. In case of oil-free lubrication, it is important to have a complete lubricating film on the seal face, which should be done before installation to ensure a long service life of the seal. Material: The standard material is synthetic rubber based on NBR with a hardness of 5 Sh.
