O-ring specifications mainly include UHSO ring specifications, UHPO ring specifications, UNO ring specifications, DHO ring specifications, piston rod O-ring specifications, high temperature O-ring, high pressure O-ring, corrosion-resistant O-ring, wear-resistant O-ring.

O-ring is suitable for installed in a variety of mechanical equipment, in the specified temperature, pressure, and different liquid and gas medium, in the static or motion state from the sealing effect.

The choice of O-ring hardness is more important. Such as a power station pump turbine hardness of 70(Shore) sealing ring, often peeling, or even transverse cut, after the use of 85~90(Shore) sealing ring, the effect is ideal.

Seals are materials or parts that prevent fluid or solid particles from leaking between adjacent mating surfaces and prevent external impurities such as dust and moisture from entering the interior of machine equipment.
