60cm Thermowell (8mm(5/16′) OD) Includes duotight 8mm (5/16′) x 1/4inch thread with o-ring and nut. Ideal for the Fermzilla range 

This thermowell fits into any 8mm Hole and can literally be installed into almost any fermenter lid. It suits 4mm OD temperature probes like the RAPT Temperature Controller

Having the thermowell attach to the lid of a fermenter is ideal as it means the penetration through the fermenter body is at the top of the fermenter not below the liquid line.  This makes the whole process more sanitary and reduces the number of difficult parts to clean.

This thermowell can be pushed through a bung with a 6-8mm hole but it’s also includes the duotight bulkhead fitting that you can use to attach this thermowell to the lid of your KegMenter or FermZilla Fermenter.

This thermowell goes right into the middle of the core of your vessel meaning you get an accurate core reading of the liquid in the tank/vessel.
