Key Differences Between TYS and Kastas Hydraulic Seal Products

1. Material and Performance

TYS Sealing: TYS primarily uses materials such as PTFE, polyurethane, rubber, polyoxymethylene, nylon, and phenolic fabric-reinforced composites. It also utilizes elastomers like NBR, HNBR, and FKM. These materials are selected to meet diverse operating conditions. Advanced high-performance polymers, developed and improved by in-house material experts, offer excellent chemical resistance, high-temperature tolerance, and wear resistance. They are suitable for high pressure, high temperature, and extreme environments, ensuring long-lasting and efficient sealing performance across various industries

Kastas Sealing primarily uses rubber and polyurethane materials. However, compared to TYS’s PTFE seals, there are significant differences in raw material supply chain advantages.

2.Custom Solutions

TYS Sealing: TYS provides tailored solutions and designing and manufacturing hydraulic seals based on customers’ application requirements. TYS delivers precisely matched custom products, whether for special sizes or demanding conditions like high temperatures and high pressures.

Kastas Sealing: Kastas offers a range of standardized seals and provides customization. However, it is less competitive in meeting highly specialized needs, focusing more on conventional hydraulic and pneumatic systems applications.
