DK-33 Stainless Steel Bush with PTFE Coating is a type of self- lubricating bush. It is made with stainless steel material as the base material, spray coated with PTFE on the surface. It has high corrosion resistance and wear resistance. It is particularly suitable for strong acid, alkali, light load and medium and low speed occasions. Its wear resistance is significantly better than the single PTFE bush and graphite bush. At present, it has been widely used in chemical acid-base flow meters, pumps, valves and corrosion-resistant sliding parts in the marine industry.
