Description

The SPS rod seal has been designed for pneumatic cylinder applications. The SPS can also be used for pneumatic valves where allowed by the overall dimensions. Moreover a shorter machining of the system can be obtained thanks to the reduced overall dimensions. The profile is rounded in the middle of the dynamic lip and it has two projections on the static lip. This symmetric shape allows easier installation. The special spring shaped profile ensures high flexibility in the system even at low pressure. Standard compound reference: B0 Alternative compound reference: A0 It is important to remove flashes or cutting edges in the housing to avoid damages.
