This Weldless Sight Gauge features a glass sight gauge encased in a chrome-plated sheath. All metal parts in contact with the beer are 100% stainless steel, and the gasket is a high temp, food-grade material. You will need to drill a 1" hole in your kettle. 

Features:

• 11" Sight Gauge is perfect for up to 10 gallon kettles (dependent upon dimensions!).
• Monitor liquid level visually without opening up your kettle! Extremely useful for HLTs on the top tier of a sculpture.
• Stainless construction means the product will last for years.
• Sight Gauge disassembles easily for cleaning.
• 1/2" FPT on sight gauge base means you can upgrade with a thermometer!
