How to Select a Hydraulic Seal
The correct hydraulic seal is determined not only by size, but also by the seal’s function in the system and the actual operating conditions.
View guide →How to Measure a Seal
For reliable product matching, the rod, housing and groove dimensions should be checked in addition to the used seal.
View guide →How to Determine O-Ring Size
O-Ring size is defined by inside diameter and cross-section; outside diameter can be used to check the relationship between these two values.
View guide →Differences Between NBR, PU, FKM and PTFE
The correct sealing material is determined by evaluating the fluid, temperature, motion, surface and mechanical conditions in which the product will operate.
View guide →Why Do Hydraulic Seals Leak?
The seal may not be the only cause of leakage. Product selection, groove, surface, installation, operating conditions and guiding should be checked together.
View guide →What Is the Difference Between a Piston Seal and a Rod Seal?
Both products provide sealing in a hydraulic cylinder, but their locations, contact surfaces and the direction of leakage they control are different.
