S-FLON (PTFE) seals and back-up rings are combined to achieve low friction characteristic and of elimination stick slip even at low pressure/speed conditions.

Moderate sealing performance comparing with U-packings due to the PTFE plastic seals which have higher rigidity and lower elasticity than rubber materials.

Good practice is needed to prevent scars on the delicate surface of S-FLON seals.

# STG type is well accepted by construction machines and heavy machineries sectors.
