5.4 Sealing the Pneumatic Screwed Connections
NOTICE
Sealing the pneumatic screwed connections
If pneumatic screwed connections are loosened, these will need to be sealed again after-
wards. Always use the same sealing technique as was used before they were removed.
The following sealing techniques are available:
► Sealing ring (rubber or plastic)
These are either supplied or you can use the ones used before. Check the condition of
used sealing rings for damage.
► Sealant
There are several variants of this:
Loctite 567 [03097172-xx] and Loctite 55 [03092492-xx]
After loosening the pneumatic screwed connection, clean the screwed thread and seal
it with Loctite. The sealing thread for Loctite 55 must be wound on in the direction of
the screwed thread.
There may also already be a sealant on the screwed thread.
