This utility model discloses a PTFE sealing structure for a hydraulic breaker, including a cylinder body with a hammer head, and a sealing ring disposed on the outside of the hammer head. A first lip and a second lip with the same inclination angle are fixedly installed in the sealing ring, and a tail lip is symmetrically arranged on the second lip. A storage cavity is formed in the sealing ring. The PTFE sealing structure for a hydraulic breaker provided by this utility model forms a double barrier against external dust through the first and second lips. Adhering dust entering the inner ring of the sealing ring is intercepted by the second lip, effectively reducing the problem of dust continuing to penetrate and aggravating wear. When oil carrying dust continues to seep from the second lip to the tail lip, the accumulated oil seeps into the storage cavity from the one-way flap, allowing the storage cavity to absorb and store this portion of oil mixed with dust. This also reduces the risk of oil leakage and minimizes the situation where dust remains in the oil on the hammer head surface, thus reducing wear.
