Most failures do not occur during operation—but during installation.
Common issues in practice:
▪️ Sealing lips are damaged by sharp edges
▪️ The seal is installed upside down (pressure side not observed)
▪️ Installation without sufficient lubrication
▪️ Torsion caused by misalignment or overstretching
▪️ Tolerances and surface roughness are not maintained
The consequences?
– Leaks shortly after commissioning
– Premature wear on the seal and piston rod
– Unplanned downtime and unnecessary costs
Our approach at ttv:
We don’t view rod seals as individual parts, but as part of a system comprising geometry, material, surface finish, and installation process.
Because: Even the best seal is useless if it is installed incorrectly.
