Hydraulic Rod Seals

KOK hydraulic rod seals are designed for reciprocating cylinder applications where external leakage control and system durability are critical.

Our rod seal designs are optimized for:

• Dynamic pressure loading
• Contamination exposure
• Extrusion resistance
• Long-term dimensional stability

Material selection and profile design are determined based on operating pressure, speed, temperature, and fluid compatibility.

Available in polyurethane, NBR, and PTFE-based configurations depending on application requirements.
