3-Gallon Vacuum Chamber, Tempered Glass Lid, 304 Steel

3 gallon vacuum chamber helps you degas silicone, resin, and polyurethane to reduce bubbles for cleaner casts, coatings, and stabilization work. Built with a 304 stainless steel chamber and a thick tempered glass lid, it’s designed for clear visibility during degassing and reliable sealing for extended vacuum holds. An oil-filled gauge, airflow control valve, and flexible hose make setup and adjustment straightforward for workshop and lab-style use.

• Delivers up to -29 inHg vacuum for effective degassing and vacuum extraction tasks.


• Seals with gasketed tempered glass lid plus threaded valve connections to help reduce leaks over time.


• Withstands corrosion and splash exposure with 304 stainless steel construction for repeated use.


• Enables easy monitoring through a 0.75 in thick tempered glass lid for clear process visibility.


• Includes noise- and dust-reducing intake muffler, non-slip silicone pad, and a 59 in flexible hose.

Whether you’re stabilizing wood, pulling bubbles from silicone molds, or running resin and polyurethane projects, this vacuum degassing chamber is built for repeatable results and quick adjustments. The shock-absorbing oil-filled gauge supports precise readings, while the control valve helps you dial in vacuum level without guesswork. Add it to your bench now to streamline pours, reduce rework, and keep your process visible and controlled—grab yours today.
