LAVA Suction Device / Container Attachment

What It Does and When You Need One

A LAVA vacuum sealer seals bags directly, but containers, jars, and bottles need this attachment to bridge the sealer and the valve.

Bridge Connects the sealer hose port to container valves

Plastic High-quality plastic attachment for regular use

Included Supplied with every LAVA vacuum sealer

Spare Also sold separately as a replacement or second attachment

The Link Between Bag Sealing and Container Sealing

The same LAVA sealer can vacuum bags, containers, jars, and bottles. This attachment is what lets the machine pull air from anything with a compatible valve.

How It Connects

It plugs into the sealer's hose port and sits over the valve on a LAVA vacuum lid, container, or bottle stopper.

What It Allows

Once connected, the machine pulls air out of the container rather than a bag, opening up storage options beyond freezer bags.

Why Buy a Separate One

Most owners already have one in the box. This listing is for buyers who have misplaced theirs, want a spare, or run more than one setup.

Use It Beyond Bags

Containers Keep leftovers fresh in LAVA vacuum containers.

Jars Vacuum preserving jars with compatible LAVA accessories.

Marinating Marinate in minutes rather than hours using vacuum containers.

Bottles Help stop an open bottle of wine from oxidising.

Connect Hose

Attach the hose connection from the LAVA vacuum sealer.

Place on Valve

Sit the attachment over the valve on the lid, container, jar, or stopper.

Draw Out Air

Let the sealer pull air from the container instead of a bag.

Small Part, Big Range of Uses

The same sealer you use for freezer bags can also handle containers, jars, marinating, and bottles once this attachment is connected.

Best For

LAVA sealer owners who want to vacuum containers, jars, or bottles, and anyone needing a replacement or spare attachment.

Works With

Any LAVA vacuum sealer that has a hose connection, used together with LAVA vacuum containers, lids, and bottle stoppers.

Vacuum Cover for Jars — Common Questions

What jars does it fit?

Bulbous twist-off jars and two-piece aluminium preserving jars with an 8 to 9cm screw cap, up to a maximum 8.5cm lid diameter. These are the most common round jar sizes. For other shapes or larger jars, see the Flex Jar-Sealer.

What do I need to use it?

Any LAVA vacuum sealer with a container mode. You connect the cover to the sealer with the included hose, then run the vacuum. The cover does not seal jars on its own; it needs the sealer to draw the air.

How is this different from the Flex Jar-Sealer?

This is a rigid bell sized for standard round twist-off and preserving jars up to 8.5cm lid diameter. The Flex Jar-Sealer is a flexible silicone bell that fits a wider range of jar shapes and sizes up to 106mm. Choose this cover for standard round jars; choose the Flex for mixed or larger jar shapes.

Can I use it for home preserving and canning?

Yes. Pulling a strong vacuum in the jar helps the seal set and extends shelf life, which makes it well suited to home preserving as well as everyday sealing of opened jars.

How much longer will food last?

Vacuum sealing a jar can extend shelf life by around 5 to 10 times compared to simply closing it, by removing the air that drives spoilage. Actual results depend on the food and storage conditions.
