What is the importance between lubricant and sealing material in O-ring? The "lubrication" of the O-ring is a factor of some significance. In many dynamic sealing occasions and working environments. The Dongsheng ring tells you that the O-ring is lubricated by the liquid in contact with it and can also be lubricated by the same liquid used to aid assembly in the first place. It is necessary to add some lubrication to the O-ring because of the serious wear on the dry seal. In the initial assembly, the same situation. All metal parts that come into contact with the seal prior to assembly, as well as the O-ring itself, should be lubricated. This is suitable for static sealing and dynamic sealing.

In general application, apply with high soluble point grease. The O-ring seal and groove can achieve the effect of lubrication. For special applications, a lubricant suitable for the relevant system and operating conditions should be selected (Table 1 below shows the use of lubricants and sealing materials for part of the O-ring).
