Burp lids wide-mouth mason jar lids — 4-pack with extraction pump, vacuum-sealing waterless airlock & date tracker

Burp Lids wide‑mouth mason jar lids are vacuum‑sealing, waterless‑airlock lids with a built‑in date tracker and an extraction pump for easier curing, fermenting, harvesting, and canning.

These lids replace standard ring-and-flat jar closures with a patented valve that lets trapped gases escape while allowing you to remove oxygen on demand. The set includes four lids and a handheld pump so you can create and maintain a vacuum without repeatedly twisting and prying. Designed for wide‑mouth jars, the system speeds routine jar maintenance, helps control internal atmosphere, and keeps batch dates visible at a glance.

How do Burp Lids simplify daily burping and maintenance?

Instead of loosening lids by hand, the included extraction pump lets you remove air through the lid’s valve for fast, repeatable burping. The waterless airlock design vents gas without introducing moisture, and the valve reseals when finished.

• Use the pump to extract oxygen in seconds — no twisting or prying.
• Waterless valve prevents added humidity during venting.
• Valve reseals automatically to hold a vacuum between sessions.

What features help me track and protect each batch?

Every lid has a patented, integrated date tracker so you can mark the start or key milestones for each jar. The vacuum seal reduces oxygen availability inside the jar, making it harder for airborne contaminants to establish compared with jars left loosely closed.

• Embedded date tracker for quick batch identification.
• Vacuum seal limits oxygen inside the jar to slow unwanted growth.
• Transparent jar compatibility lets you visually inspect contents without opening.

Will these lids work with my jars and processes?

Burp Lids are sized for standard wide‑mouth mason jars and are intended for non‑pressurized curing, fermenting, harvesting, and home canning routines that benefit from controlled venting. They are not designed to replace pressure canning lids for high‑temperature, high‑pressure sealing.

• Fits most wide‑mouth mason jars and standard threads.
• Great for controlled venting during curing and fermentation.
• Not a substitute for pressure canning lids in pressure cooker canners.

How do I use the pump and care for these lids?

Set the lid on a clean jar, press the pump to the valve, and draw air out until you reach the desired internal pressure. Wipe the valve clean after use and hand‑wash lids; avoid putting the pump in hot dishwashers to preserve seals and moving parts.

• Place lid, attach pump, pump several times to evacuate air.
• Hand‑wash lids and pump; avoid harsh heat on the pump assembly.
• Rotate the date tracker when starting a new batch for clear records.

Who is this for? Burp Lids are ideal for home fermenters, herb curers, and hobbyists who use wide‑mouth mason jars and want a cleaner, faster way to manage jar atmosphere and track batches. If you regularly open jars to vent gases or need a simple way to reduce oxygen exposure between checks, this 4‑lid kit with extraction pump gives a repeatable, waterless solution that saves time and keeps your workspace tidier.
