Red glycol insulation hose – 12 mm ID x 16 mm OD

2m roll of red glycol insulation hose (12 mm ID x 16 mm OD). For optimal insulation, the hose is encased in 15mm thick foam.

The return loop from your jacketed fermenter should ideally use this red insulation hose to indicate the warmer side. For the side that comes directly from the cooling circuit of your glycol chiller, we recommend using the blue insulation hose.
