??Xinhua Xu rubber products company - is specialized in the production of high-quality import O-ring, our superiority in this regard:

??1, has a very good sealing effect, and with the increased pressure of the hydraulic oil and automatically increases the sealing effect; even at high pressure and high temperature and other harsh working conditions, hydraulic seal leakage and no significant increase in the amount of leakage pole small.

??2, in order to avoid or reduce the low-pressure hydraulic equipment generates crawling and other undesirable phenomena, seals have low static friction and dynamic friction, and the friction coefficient should be very stable, that friction is small.

??3, the seal ring may be required due to long-term immersion in hydraulic oil, highly swelling, dissolution or embrittlement harden the like, so that the loss of the sealing effect, thus requiring seals have good compatibility.

??4, seal all imported raw plastic materials, with good elasticity, heat resistance, cold resistance, pressure resistance, wear resistance and certain physical and mechanical strength, and long service life.

??5, import Xinhua Xu rubber products company seal is easy to manufacture and use, high precision sealing surface, looks beautiful, and inexpensive low grid.
