Upgrade Collar for FermZilla Gen 3 to Gen 3.2

Product detailed description

This collar enables an easy transition from the original 64mm butterfly valve to the new 91mm version, compatible with the 600ml collection bottle and Tri-Clover clamps. The upgrade ensures better sealing and simplifies maintenance, cleaning, and sanitization.

Instructions:

1. Unscrew the 6 x Bolts with a 5mm Allen Key from your current Tri-Conical Butterfly Valve. There will be a washer for each nut, try not to lose it!
2. Peel apart the butterfly valve, having the 1000mL Collection container attached makes this part a little bit easier as you'll have more to grip onto.
3. Once apart put aside the 2" Section and replace with the 3" Section. Take note of the orientation as there are grooves to show which direction the butterfly gate can go.
4. Screw Back together, tightening a little bit by little bit in sequence. Overtightening may cause the nut to round out the plastic, be careful.
