?Rubber O-ring tensile! !

??The amount of stretching the size of the rubber O-ring affect the life of the O-ring, the inner diameter of the actual general rubber O-ring groove bottom diameter of less than or piston rod of the liver, so the rubber O-ring is stretched under the state of installation, the amount of stretch is too small will produce breakage occurs distortions excessive stretching installation, section thickness uneven.

??Rational use of stretching of the rubber O-ring used in the national standard molds, reduce the variety of non-standard parts.

??Rubber O-ring stretched too large circle pressure increase that loses its elasticity, resulting in deformation of the rubber O-ring is generally produced by the compression spring to be sealed, but as the pressure increases, the seal is extruded cloud gap arising from changes in shape, in order to make the rubber O-ring seal and has a good long life, you must make the installation groove and sealing parts O-shaped rubber seal gaps properly designed, when the gap is too large rubber O-type ring under the action of hydraulic pressure to squeeze the gap, resulting in damage, causing leakage.

??Learn the rubber O-ring tensile, increase the service life of the rubber O-ring, increase economic efficiency !!!
