Product Solutions

PEEK (polyetheretherketone) fittings and plugs have excellent chemical corrosion resistance and mechanical strength, and are widely used in fluid control and piping systems. They provide high-performance and reliable sealing, ensuring the long-term stable operation of the system.

PEEK (polyether ether ketone) screws and nuts are widely used in aerospace, automotive, and electronics and appliances due to their excellent high temperature resistance, chemical resistance, and high mechanical strength. They ensure high reliability and longevity of connections, making them ideal for demanding environments.
