🔍 What Are Hydraulic Seals and Why Are They Critical?

Hydraulic seals are specialized sealing elements used in hydraulic cylinders, pumps, and actuators to block or contain fluid under pressure. Their function is two-fold:

• Prevent internal leakage of hydraulic fluid, maintaining system pressure

• Exclude contaminants such as dust, water, and debris from entering the cylinder

CFKS manufactures a full line of dynamic and static seals, including:

• Rod Seals (UN, UNR, UHR): Maintain tight sealing between piston rod and cylinder

• Piston Seals (KDAS, UTS): Seal between piston and bore to ensure effective pressure buildup

• Wiper Seals (DHS, GA): Clean contaminants off the rod during retraction

• Guide/Wear Rings: Prevent metal-to-metal contact, improving service life

• Buffer Seals & Back-Up Rings: Absorb high-pressure spikes and prevent extrusion

These seals are critical for hydraulic cylinders operating under high pressures (up to 40MPa or more), high-frequency cycles, and harsh environments.

🔬 Material Technology: PU, NBR, FKM, PTFE — Engineered for Performance

CFKS hydraulic seals are available in a wide range of high-performance materials to ensure chemical compatibility, wear resistance, and durability:

• PU (Polyurethane): Excellent wear and extrusion resistance, ideal for dynamic sealing

• NBR (Nitrile Rubber): Cost-effective and oil-resistant, suitable for general hydraulic applications

• FKM (Fluoroelastomer): High temperature and chemical resistance for aggressive media

• PTFE (Teflon®): Low friction, non-stick surface, suitable for dry running and high-speed systems

All CFKS materials are tested for compression set, fluid compatibility, tensile strength, and hardness (Shore A/D), ensuring long-term sealing stability in both low-speed and high-speed cylinder applications.
