Thread Tap set for 90° compact air fitting to be used on factory air horns when fitting roof bar on Scania Next Gens.
Usually when fitting roof bar (such as Kelsa HiBar, etc), the factory fitted air horn will need to be mounted on new brackets with the air fitting port facing down towards the roof with very little space for the air pipe to enter. To fix this issue you can purchase our compact 90° air fittings here
When fitting these air fittings to the factory Scania air horns, the horn needs to be re-threaded with this thread tap set. No drilling is required just carefully thread in the taper tap, then the plug tap to ream the existing thread. Then simply thread in the new air fitting and gently tighten, then you are ready to re-fit the horn to the truck
