3.8.1. General Directions for Use of Aanaerobic Sealing Materials
Cleanliness of components
Non-metallic surface protection must be removed. In case of repair works, soiled and oily components are to be
cleaned and residues of adhesive synthetic are to be removed. Tapholes are recut with an appropriate tap and
blown off with compressed air.
If solvents or degreasing agents are used for cleaning, make sure that they have volatilized before application
of the synthetic.
Storage
At temperatures below 28° C, 1 year minimum.
Directions for securing (S)
Indication: SM ....... Medium-tight Securing (the connection can be loosened without problems)
Indication: SF ........ Tight Securing (the connection is difficult to loosen)
Application:
Screw joints
Fixing procedure
In general, it is sufficient to apply the synthetic on the screw thread.
If screws are screwed into socket threads, only wet the taphole in order to let the air escape during screwing.
Screws or nuts to be tightened with a specified torque are slightly oiled on their contact surface or housing
section.
Directions for fixing (B)
Indication: BM ....... Medium-tight Fixing
Indication: BF ........ Tight Fixing
Application:
Joint connections, sleeves, gear wheels, pulleys, bearings etc.
Jointing procedure
For jointing connections, both jointing parts are to be wetted. Wetting should completely cover the jointing
surfaces. In case of sliding fits, the parts are encased by turning.
No strength may be exerted to the connection until sturdiness is reached (for duration see table 1).
Directions for sealing (D)
Indication: DR ....... Sealing of pipe joint connections
Indication: DF ........ Sealing of plane surfaces
Application:
Sealing of threads, screwings, joint connections and plane surfaces.
