JIANBENKJ Sight Glass Spigot for Berkey & Gravity-Fed Water Filtration – 10in Clear View

Enhance visibility and control with a clear view spigot

The JIANBENKJ Sight Glass Spigot is designed for Berkey and other gravity-fed filtration tanks. The 10‑inch glass gauge provides a crystal-clear window into your reservoir, while a bright red floating ball moves with the water level. You can gauge remaining volume at a glance without opening the upper chamber, helping you plan refills with more confidence and consistency.

Crafted for durability, this spigot blends solid brass with an electroplated finish, a 316 stainless steel spring, a food-grade silicone seal, and a glass water gauge. The result is a robust component that fits into daily use with a clean, minimalist look and dependable performance.

Compatibility and fit

Designed for broad compatibility, it works with popular Berkey models (Travel, Big, Royal, Imperial) as well as Waterdrop King Tank Series, Alexapure Pro, and Purewell systems. Before installing, verify the connection type and dimensions to ensure a snug, leak-free fit.

Leak-free, precise installation

The spigot features a solid brass main body, a 316 stainless steel spring, a food-grade silicone seal, and a glass gauge for a steady, dependable seal. It threads into the lower chamber securely, with a flat seal that stays in place as you tighten.

Overflow awareness and water management

The red float provides a straightforward read on remaining water, helping you decide when to refill to maximize filter use and minimize waste. A visible water level on the glass can help you space refills to match your needs without guesswork.

Easy installation and practical use

Along with a complementary wrench, this sight glass spigot is straightforward to install. You’ll enjoy a clean, continuous flow and a replacement that aligns with your existing filtration setup.
