Metal-to-Metal Seal Oil

Keep your pressure canner sealing safely and reliably, every time. This approved and tested lubricating oil is designed for the metal-to-metal sealing surfaces of pressure canners and sterilizers — helping you maintain a proper, airtight seal for safe canning and sterilization.

A proper seal is everything in pressure canning. Without adequate lubrication, metal-to-metal sealing surfaces can wear unevenly, allow steam to escape, and compromise the pressure needed for safe food preservation.

Our Metal-to-Metal Seal Oil is formulated to lubricate and protect the critical sealing surfaces of your pressure canner or sterilizer — specifically the inside rim of the lid and the corresponding rim on the pot where the lid locks down. A thin, even application before each use helps ensure a consistent, airtight seal that holds pressure and performs reliably batch after batch.

Packaged in a convenient applicator bottle for precise, mess-free application, this oil is a simple addition to your canning routine that protects your equipment and gives you confidence that every jar is processed safely.

How to Use: 

1. Inspect your unit. Ensure the sealing surfaces are clean and free of food debris before applying.
2. Apply to the lid rim. Use the applicator and squeeze the bottle to apply a thin, even layer of oil to the inside rim of the lid.
3. Apply to the pot rim. Apply the same thin layer to the rim of the inside of the canner where the lid seats and the metal-to-metal seal makes contact.
