Kintowe K659 is a high-quality single acting piston seal that is reliable and efficient in a large range of applications. It has been designed to offer effective bore sealing and offers improved sealing and compression set characteristics compared with conventional Y rings. The short and robust outer dynamic lip ensures that the seal provides a superior level of sealing performance.
The added benefit of the secondary lip pocket for lubrication ensures optimal performance and maximizes the lifespan of the seal. K659 single acting piston seals guarantee that you get a seal that is durable, effective, and easy to install.
The single acting piston seal is a cost-effective and reliable sealing solution for applications that require high-performance and long-lasting seals. It is an excellent option for a broad range of industries like automotive, industrial machinery, hydraulic pumps, and more.

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.
