Products Description
K673 polyurethane single lip rod seals
Advantages:
☆ Simple installation
☆ No leakage if used with K864 or K839 wipers
K673 is an outstanding solution for medium and heavy-duty applications where dry rod sealing is of paramount importance. This asymmetric seal offers superior performance and reliability, ensuring that your equipment remains in top condition for longer periods.
The single lip design of the seal is a highly efficient solution for various applications. It can effectively prevent contaminants from penetrating into the system and ensure smooth operation. Although a double lip wiper is usually preferred in some situations, the single lip design can still provide excellent performance and reliability.
The single lip rod seal's asymmetric design allows for easy installation and smooth operation, while its robust construction ensures longevity and durability even in challenging environments. K673 is an excellent choice looking a reliable, high-performance dry rod seal for medium and heavy-duty applications. Its superior sealing capabilities, robust construction, and easy installation make it a top choice for engineers and equipment maintenance professionals.

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.
