Products Description
DF 754 hydraulic cylinder double acting piston seals
Advantages:
☆ Low starting force and operating friction
☆ Excellent wear resistance
☆ Compatible with most hydraulic fluids
☆ More tolerance to contamination than common PTFE equivalents
☆ Rapid recovery of face after assembly, unlike common PTFE surface rings, it doesn't need to be remolded.
☆ Ideal for use with Kintowe DFG guide tapes & PFC guide ring
Kintowe DF 754 hydraulic cylinder double acting piston seal is designed to provide a more efficient and reliable hydraulic cylinder. This compact low friction seal is perfect for light to medium duty hydraulic cylinders, making it ideal for a wide range of applications.
One of the key features of this piston seal is its wear-resistant elastomer face, which ensures a longer lifespan and better performance. Additionally, the seal is pre-loaded by an O-ring, which further enhances its sealing capabilities.
The narrow width of the seal housing allows for the use of a narrow piston, which can save space and reduce the overall weight of the hydraulic cylinder. However, it is important to note that an adequate bearing should be mounted on one or both sides of the seal to ensure optimal performance.
The hydraulic cylinder double acting piston seals have improved the functionality of hydraulic cylinders. Its compact design, low friction, and reliable performance make it a must-have component for all light to medium duty hydraulic cylinders.

By Express (FedEx, UPS, DHL, TNT, EMS, etc. )
--- Advantage: Fast (takes about 7 - 10 days in the delivery), door to door
This is especially useful for urgent shipments that need to reach their destination quickly. Though express delivery is a little expensive, it is worth the cost if time is a crucial factor.
By Air Transportation
--- Advantage: Fast (takes about 8 - 12 days), a little cheaper than Express.
Though it takes a little longer than express delivery, at around 8-12 days, it is still relatively quick. Additionally, air transportation is a little cheaper than express delivery. The only downside is that the receiver has to collect the goods from the airport.
By Sea (Ocean ) Transportation
--- Advantage: Much cheaper than Express or Air transportation.
Sea transportation is an excellent option for individuals and businesses that need to transport goods across long distances. With its cost savings and global coverage, it's an attractive alternative to other transportation methods.
