Sight glasses are part of our Cellar & Brew Fittings Range. These has been developed to provide better access to specialist process equipment that is commonly used across New Zealand in the food and beverage industries.
The Metal Company offers the Sight Glass with tube, Tri Clover ferrules and RJT male-female connections.
We have two different types of glass tubes that come with our Sight Glasses. Our standard option is Polycarbonate, which has a temperature rating of 80°C; however, we also stock an Acrylic option depending on your application. The maximum pressure rating of these tubes is estimated to be 2 bar (29 psi). Please note that not all liquids, chemicals and substances are suitable for use with Polycarbonate or Acrylic sight glasses. We have a handy compatibility chart available below which you can use to determine which Sight Glass is suitable for you.
The standard seals holding the glass in place are made of the PTFE rubber and kits are available for replacing seals that have worn over time.
