Vacuum Mason Jar Pro

Each set includes all three pieces: the clear glass jar, the stainless steel vacuum lid with date tracker, and the stainless steel screw band. Everything you need is in the box — nothing sold separately.

The lid and band are 86mm wide and fit all three sizes — 16 oz, 32 oz, and 64 oz — so you can mix jar sizes and use the same lids across your entire collection.

The jar is food-grade glass — BPA-free, odor-proof, and completely non-reactive with acidic foods like citrus, tomatoes, or vinegar ferments. The lid and screw band are food-grade stainless steel, which does not rust, corrode, or leach under normal use.

All three pieces are dishwasher safe and built for hundreds of reuse cycles — unlike standard tin canning lids that are designed for one use and thrown away.

To activate the vacuum seal, yes — a Hausware vacuum sealer is required. Press the nozzle onto the white valve at the center of the lid, hold the button, and all the air is removed in seconds. The valve locks it automatically, keeping your food fresh significantly longer.

Without the vacuum sealer, the jar still functions as a regular airtight mason jar — great for everyday storage, but the air is not removed from inside. The built-in date tracker dial works either way, so you always know exactly when you sealed it.

How much longer does food actually stay fresh compared to a regular jar?
When vacuum sealed with the Hausware sealer, food lasts up to 3–5 times longer. Fermented vegetables that typically last 1–2 weeks can stay fresh for 4–6 weeks. Dry goods like nuts, coffee, and spices stay flavorful for months instead of weeks. Removing oxygen stops oxidation and slows microbial growth — the two main causes of spoilage.

Will it leak if I store liquids or turn the jar on its side?
When the screw band is tightened properly, the silicone gasket creates a firm, leak-resistant seal against the jar rim — suitable for soups, brines, juices, and marinated foods. We recommend keeping liquid-filled jars upright during storage. The lid is designed for airtight sealing, not pressure-resistant containment when inverted or shaken.

Can I put the jar in the freezer or use it for hot food?
The glass jar is freezer safe — leave at least 1 inch of headspace at the top to allow for liquid expansion. For hot food, let it cool to room temperature before sealing. Do not place a cold jar directly into boiling water or a hot oven, as sudden extreme temperature changes can crack the glass.

How do I know if the vacuum seal is still holding?
Press the center of the lid with your finger. If it does not flex or move, the vacuum is intact. If it flexes or pops, the seal has been lost — simply re-seal with the Hausware vacuum sealer in under 10 seconds. You can check this anytime without opening the jar or disturbing the contents.

How do I clean the lid — can I put it in the dishwasher?
Yes — the glass jar, stainless steel lid, and screw band are all fully dishwasher safe. The vacuum valve port is recessed and sealed so water does not enter the mechanism during washing. Periodically inspect the silicone gasket for wear. Replacement gaskets are available separately so you never need to replace the entire lid.
