Piston Ring K17 60x44.5x6.3

Applications in Hydraulic Systems and Industrial Machinery

The K17 60x44.5x6.3 piston ring is a precision-engineered hydraulic seal designed for use in piston assemblies of hydraulic cylinders. In English search trends, users commonly look for phrases like “hydraulic piston seal K17”, “PTFE piston ring 60x44.5x6.3”, “K17 seal for cylinder”, or “hydraulic cylinder piston seal kit”.
This model provides excellent sealing performance, preventing fluid leakage under high pressure while ensuring smooth piston movement. It is widely used in industrial hydraulic systems, mobile machinery, and maintenance applications where reliability, dimensional precision, and long service life are essential.

Key Advantages and Technical Characteristics

The K17 piston ring combines a PTFE-bronze sealing ring with an NBR (nitrile rubber) O-ring, delivering superior wear resistance and effective oil sealing. The bronze-filled PTFE ensures low friction and minimal wear on cylinder surfaces, while the NBR O-ring provides the necessary elasticity and oil resistance.
This construction guarantees high durability, excellent resistance to hydraulic oils and greases, and reliable sealing in demanding environments.
Standard dimensions of this model are 60 mm outer diameter, 44.5 mm inner diameter, and 6.3 mm height, making it compatible with most cylinder housings in the K17 standard design — one of the most popular configurations in modern hydraulic engineering.

FAQ - Frequently Asked Questions

1️⃣ What makes the K17 piston ring different from other types?
The K17 design features a PTFE-bronze ring combined with an NBR O-ring, ensuring optimal sealing performance and reduced wear. Compared to other profiles, such as K15, this design offers better stability and durability in high-pressure systems.

2️⃣ How do I select the correct piston seal size?
Match the outer diameter (60 mm), inner diameter (44.5 mm), and height (6.3 mm) to the cylinder’s housing dimensions. Correct fitment ensures leak-free operation and maximum seal efficiency.

3️⃣ What applications is this piston ring suitable for?
It is ideal for hydraulic cylinders, industrial presses, construction machinery, forklifts, and mobile hydraulics, where high sealing performance and resistance to pressure are required.

4️⃣ Is NBR suitable for hydraulic oils?
Yes. NBR (nitrile rubber) provides excellent resistance to oils, fuels, and hydraulic fluids, making it ideal for standard hydraulic applications.

5️⃣ Can this product be delivered quickly?
Absolutely. The K17 60x44.5x6.3 piston ring is available for immediate dispatch with 24-hour delivery across Poland and the EU.
