Products Description
K780 double acting piston seals
Advantages:
☆ Cutting design for back-up rings & wear rings, easy to install
☆ Strong extrusion resistance, long using life
☆ The processing accuracy of the cylinder is not high
Kintowe K780 double acting piston seal is a robust assembly designed specifically for single pistons, which uses a rubber sealing element that has proved itself in service to be extremely wear resistant and capable of working most effectively in a wide range of medium duty applications. This piston seal is also suitable for double pistons.
The assembly comprises a rubber sealing element, two split support rings and two split L-shaped guide rings, one of each located either side of the seal.
The nitrile rubber sealing element is designed with multi-lips for efficient dynamic sealing with minimal low friction and when pressurized, be protected from extrusion damage by the extending lips of the support ring. The guide ring is manufactured from a tough, flexible polymer and scarf cut for assembly.
Both the L-shaped guide rings are grooved to ensure that the fluid pressure properly energized the sealing element and to prevent the possibility of any pressure trapping within the seal assembly.
The K780 double acting piston seals are the reliable and durable solution for single and double pistons. It is capable of working effectively in a wide range of applications, making it a valuable asset to many different industries. Whether you are working in manufacturing, construction, or any other field that requires reliable piston seals, the K780 is an excellent choice.

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.
