Flexible Rubber Sealing Ring

Introduction of O ring seal
Rubber O ring seal is the most widely used in hydraulic and pneumatic transmission system of a seal.
Rubber O ring seal is a kind of cross section for the circular rubber sealing ring, due to its cross section is type O, so called type O sealing ring, also called o-rings. Began to appear in the middle of the 19th century, when use it as a steam engine cylinder sealing element

Classification of O ring seal
1. O-ring seal specifications, the specifications are mainly UHSO rings UHPO ring specifications, the specifications, UNO rings DHO ring specifications, the piston rod o-ring specifications, high temperature resistant o-ring, o-ring resistance to high pressure, corrosion resistant, o-ring, o-ring wear resistance.
2. The o-ring seal main standard of GB 1235-76, GB GB3452.1-92; The P TYPE, G TYPE, S TYPE, SS/V TYPE, F TYPE; AS568 American standard, British standard series; European standard series [1]

Features of O ring seal
1.Rubber O-ring sealed performance is good, service life, high dynamic pressure seal service life 5 to 10 times higher than conventional rubber seal products, up to dozens of times, under certain conditions can and sealing matrix with life.
2. Rubber O-ring small friction resistance, dynamic and static friction force is equal, is "0" shaped rubber ring friction 1/2-1/4, can eliminate "creeping" phenomenon in low speed, low pressure motor.
3. Rubber O-ring seal high wear resistance, with functions of automatic elastic compensation after sealing surface wear.
4. Rubber O-ring good self-lubricating properties. Free oil sealing.
5. Rubber O-ring seal has simple structure, easy to install.
6. Rubber O-ring working pressure: 0-300 mpa; Speed: 15 m/s or less; Working temperature: 55-250 degrees.
7. Rubber O-ring applicable medium: hydraulic oil, gas, water, mud, oil, emulsion, water - ethylene glycol, acid.
