??Installation should pay attention to what O-rings

??1. Do not damage the O-ring sealing surface or sealing surface line

??O-ring sealing plane of the upper and lower end faces depend; sealing performance depends on the bore hydraulic seal O-ring or shaft associated with the lip line, these parts by both soft and rich elasticity of temperature, corrosion resistance , anti-aging graphite, rubber, fiber vulnerable to damage these special materials, and therefore more need in the handling, installation and storage process given special protection and care, once damaged seal area often give a big risk to stay ;

??2. Do not force the installation

??Some O-ring seal is placed in the slot-like stuffing, in which case you need to bear with the installation, construction can not be rough, brutal, action will disrupt a lot of force loaded seal original prefabricated structure, which is like the pre- Fill in the required concrete shattered after disaster will inevitably lead to the same site. Installation of such seals must be very careful, be careful, to be embedded in the successive step by step;

??3. The need to pay attention when installing the balance, symmetry

??The O-ring seal is placed exactly closely the effective sealing surface (or lip line) position. System opened to use after remedial work needs to be done further observation and fastening seal to prevent leakage caused by micro system outburst during operation due to changes in working conditions (eg booster) occurs.
