Information

Operation and application criteria of breather plugs GN 774 see operation 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).
