Assembling

 

It is forbidden to add sealant and other fillers. In order to obtain better sealing effect, the sealant is

 

coated with sealant, the sealant is driven into the hydraulic system

 

when connecting the pipe, the pipe should be sufficiently deformed to avoid tension

 

when connecting the pipe, it should be avoided to be subjected to lateral force, and the lateral force will

 

cause the seal to be lax when connecting the pipeline, should be a good one, to avoid multiple removal,

 

otherwise it will make the sealing performance worse.
