Information
Function and operational criteria of breather plugs GN 774 see function description.
Breather caps are fitted either with a threaded neck or with a bayonet connection and they can also be combined with a filler strainer GN 664 or GN 664.1.
The bayonet version is fitted with a chain to avoid losing it.
MAX-MIN markings can easily be added to the flats of a dipstick (see GN 109).
