  • Materials are not allowed to come into contact with acids,alkali,oils and various solvents during storage to avoid exposure to sunlight,arc light and otherS.

Installation:

  • Use tools without sharp edges.
  • Ensure that the O-ring is not twisted,and do not stretch the O-ring excessively.
  • Try to use an auxiliary tool to install O-ring,and ensure correct positioning.
  • For bonding with a sealing strip,the O-ring must not be stretched at the joint.
  • When the O-ring is stretched,the mounting mandrel must be used when passing screws, keyways, etc.The mandrel can be made of soft,smooth metal or plastic without glitch or sharp edges.
  • When installing the compression screws,tighten the screws symmetrically and do not tighten them in the direction.

Some Tips Before Installation(Please Check):

  • Whether the angle is machined according to the drawing.Whether the sharp edge is chamfered or rounded.
  • Whether the inner diameter removes the glitch surface or not.
  • Whether the seals and parts have been greased or lubricated.
