Coated on the outside surface of threads, playing the
role of locking, sealing and resistance to looseness
due to shock, with high strength.
4
Loctite 275
Green
Coated on the pipeline and connection portion
5
Loctite 510

(Orange )
Coated on the shiny metal surface to function as
sealing. For example: the joint faces of the cylinder
block and flywheel housing.

Suitable for sealing the space between core and hole
and applied to the oil chamber and oil passage, such
as the cylindrical surface of bowl-plug.
