This part is custom made for KegLand and is a part you can use to drill a 45-47mm hole into the wall of a tank or lid of a fermenter then fit this 2inch tri-clover fitting without any welding.

The internal diameter is 35mm. The tri-clover flange fits other 2" tri-clover fittings.

This makes for a very easy way to fit the tri-clover fitting.

This is perfect if you want to fit an extension tube or steam condenser to a BrewZilla.
