?Advantages Xu XinhuaXu rubber seals where

??1.  XinhuaXu rubber seals have very good sealing effect, and with the increased pressure of the hydraulic oil automatically improve its sealing effect; even at high pressure and high temperature and other harsh working conditions, hydraulic seal leakage and no significant increase the amount of leakage is minimal.

??2. XinhuaXuXurubber seals to avoid or reduce the low-pressure hydraulic equipment generates negative phenomena such as crawling, imported seals have low static friction and dynamic friction, and the friction coefficient should be very stable, that friction is small.

??3. Because of the rubber seals may require long-term immersion in hydraulic oil, easily swell, dissolve or harden brittle, so that the loss of sealing effect, thus requiring seal has good compatibility.

??4. XinhuaXu rubber seals all imported raw rubber material with good flexibility, heat resistance, cold resistance, pressure resistance, abrasion resistance and a certain physical and mechanical strength, and long service life.

??5. Our imported production seal easy to manufacture and use, the sealing surface machining high precision, beautiful appearance, almost no flash burr, inexpensive and low grid.

?  XinhuaXu rubber seals in terms of wear-resistant materials are commonly used nitrile rubber, EPDM, fluorine rubber.

??Nitrile rubber seals cheapest commonly used in hydraulic cylinders, which are not without environmental exposure to high temperature corrosive medium. EPDM seals slightly higher price than the price of some of the advantages that the nitrile can also slightly higher temperature resistance, corrosion resistance, the drawback is intolerant of an oily substance. Fluorine rubber seals can also be understood as a nitrile rubber and EPDM bit combination, with a high temperature, wear resistance, corrosion resistance and other advantages, but the disadvantage is that higher prices.
