This sight glass fits both the 35L and 65L units. Installs in place of the stainless recirculation tube, allowing you to check your fill level at a glance, or monitor wort clarity during mash recirculation.

Intended for use with BrewZilla model 3.1.1 or later. Support brackets on older models may be too small for the 0.59″ OD polycarbonate tube.

Includes:

• Stainless 1/2″ Male BSP threaded post with o-rings
• Stainless 1/2″ Female BSP threaded post with o-rings
• 360 mm long polycarbonate tube (13 mm ID x 15 mm OD)

Please note: you may need to use varying amounts of plumber’s tape to get it to seal in the right position once it has been tightened back down on the female bottom end.

Warning: if using PBW, it is recommended to not have an extended contact time at temperatures above 120°F or exceeding the recommended dilution ratio.
