Yangzhong Kangyu Seals Technology CO.,LTD, which was founded in 2010 in Yangzhong city Jiangsu province, is the branch office in Guangzhou. And is located in the biggest construction machinery market of China.

We produce and supply different kinds of the spare parts, WR, Phenolic and Cloth Ring and PTFE used on construction seals. 

Composed of chemical fiber and epoxy resin, the product has a long service life, low friction resistance, good resilience, pressure resistance and water absorption resistance. It plays a supporting role in the hydraulic cylinder with high load capacity, and the supporting ring avoids touching the metal material of the dragging components, and has very good wear-resisting performance and shock-absorbing efficacy.

Commonly known as “Plastic King”, it is a polymer made by polymerization of tetrafluoroethylene as a monomer, with the chemical formula (C2F4)n, with excellent heat and cold resistance, and can be used for a long period of time at -180 to 260ºC. This material is characterized by resistance to acids, alkalis and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE is characterized by high temperature resistance, and its coefficient of friction is extremely low, so it can be used for lubrication as well as an ideal coating for the inner layer of easy-to-clean water pipes.
