Products Description
K735 compact double acting piston seals
Advantages:
☆ Low friction
☆ High pressure capability
☆ Long service life
☆ Variety range of material options to suit many working conditions
K735 is a compact double acting piston seal assembly designed for single piston and suitable for low to high pressure, medium to heavy duty applications.
The assembly is composed of a self-lubricating, wear-resistant bronze filled or glass/MoS2 filled PTFE cap ring that offers great durability and longevity. Additionally, it is loaded by an NBR energizer that provides excellent support and energy to the seal, ensuring that it performs optimally under varying conditions.
Moreover, the double acting piston seal comes with thermoplastic split anti-extrusion rings that provide excellent support on both sides and prevent contamination of the energizer and cap ring. This feature ensures that the assembly remains clean and free of any debris, which enhances its durability and longevity.
K735 piston seal is designed to be used in a variety of equipment and is particularly suited to use in earthmoving and other off-highway equipment. This piston seal is able to deliver reliable, leak-free performance that helps ensure optimal system function and long-term operation.

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.
