Import O-ring manufacturers in Taiwan Wall OTP top o-ring factory direct, direct import oil nitrile rubber o-rings, we have to be accurate and reliable, alternative, formula selection, parameter selection principle, be careful of various Data were analyzed icons, checking and verification of some of the limitations of technical experience and test results. After a long practice tests, which produce good performance and good quality oil imports o-ring. Imported oil O-ring our advantages: a .. a very good seal, and with the increased pressure of the hydraulic oil and automatically increases its sealing effect; even under high pressure and high temperature, such as poor working conditions, the hydraulic seal leakage no significant increase in volume, the amount of leakage is minimal. 2. superior oil resistance. 3. Our production import O-ring is easy to manufacture and use, the sealing surface machining high precision, beautiful appearance, almost no flash burr and low grid cheap. ? Import oil trench design OTP O-ring: In the case of using the movement, using a compression margin will seal O-ring when the sliding resistance, compression set, etc. have a significant influence, it is necessary to control the necessary The minimum inside. When used under the campaign, especially fast, poor lubrication conditions of case, please margin compression set is much smaller than the average movement with an O-ring.
