Use this small Universal Lid to make your own vacuum stabilizing chamber out of a wide range of containers of your choice*. This lid fits containers with a minimum inside opening of 2 1/8" up to an outside opening of 5". Includes wide rubber gasket for a long lasting seal and deep vacuum. This is NOT the same lid used with my complete chambers.
Minimum inside opening size: 2 1/8" (54 mm)
Maximum outside opening size: 5" (127 mm)
Two 1/4" NPT threaded ports provided for fittings and gauge
Wide rubber gasket
*Please be aware that vacuum is very powerful. Make sure your container is strong and able to withstand the pressures associated with stabilizing. Many people use mason jars or pickle jars but I am unable to recommend them due to liability concerns. Your choice of container is solely your responsibility!
