Products Description
K839 hydraulic scraper seals
Advantages:
● Hard wearing material for long using life
● Twin lip ensures drier sealing system
Kintowe K839 hydraulic scraper seals are a reliable and effective solution for preventing dirt and moisture from entering hydraulic cylinders. Made from high-performance polyurethane, these seals are designed for maximum wear resistance and long-lasting durability.
One of the key features of the K839 seal is its innovative design, which includes two sealing lips that are precisely proportioned to collect fluid passing the rod seal. This helps to prevent leaks and maintain hydraulic system performance over time.
Furthermore, the outer diameter of the seal is designed to fit snugly and securely in the cylinder housing, providing excellent stability and improving overall seal performance even in harsh operating conditions.
A vent between the seal and the wiper is recommended to avoid a pressure trap.
K839 hydraulic scraper seal is a top-quality sealing solution that provides dependable protection and long-lasting performance for hydraulic systems.

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.
