  • Replace a missing cork or keep matching spares: this tapered demijohn and bottle bung measures 30mm across its small end, 33mm across the top and 38mm tall. Compare those dimensions with your glass neck or an existing stopper before ordering.
  • One size, six quantity options: choose 1, 2, 4, 6, 8 or 10 bungs. Every option contains the same 30/33mm cork; a larger pack gives you more stoppers, rather than a selection of different sizes.
  • A gentle taper for a suitable neck: the smaller end enters first, with the wider top left accessible for a grip. Check the internal opening, neck shape and depth; the end diameters do not promise a fit in every demijohn or bottle.
  • Solid agglomerated cork: the textured cork construction is shown in the exact-product dimension photo. These bungs have no drilled airlock hole and are supplied on their own, without glassware or brewing accessories. Use an appropriate airlock arrangement for active fermentation.

Description

A replacement cork, in the quantity you need

A missing stopper need not mean replacing your glassware. Choose this 30/33mm tapered cork bung when its dimensions match the neck of your demijohn, carboy or bottle.

The cork is 38mm tall, with a 30mm base and a slightly wider 33mm top. Its textured, agglomerated cork body is shown in the labelled product photo.

Buy one replacement or a pack of matching spares: 1, 2, 4, 6, 8 or 10 bungs. The selected quantity is supplied in one size.

Match the stopper to the opening

The 30mm and 33mm measurements describe the cork ends. They do not mean that every opening between those figures will give a suitable fit.

Measure the inside of the neck and check its shape and depth. The smaller end must enter, while the taper needs to seat before the cork drops through. If you have a well-fitting old stopper, compare its dimensions as well.

Leave enough cork above the rim to hold when removing it. Position it gently rather than forcing it into glass. Bottle capacity alone does not identify the correct stopper size.

Same cork. More spares when you need them.

The single option is useful for one missing stopper. Packs of 2, 4, 6, 8 or 10 keep the same size ready for several matching containers. Check each neck before buying a pack for a mixed collection of glassware.

These are solid, undrilled bungs. They do not include an airlock, and a solid stopper is not a substitute for an airlock arrangement during active fermentation. This product has no specified pressure rating.

Questions about fit and quantity

Does a pack contain different cork sizes?

No. Choose the number of bungs: 1, 2, 4, 6, 8 or 10. All are the same tapered size: 30mm at the base, 33mm across the top and 38mm tall.

Can I choose by my demijohn's capacity?

Measure the neck instead. Containers with the same capacity can have different openings. Compare the inside diameter, shape and available neck depth with the labelled cork dimensions.

Is there a hole for an airlock?

No. The bung is supplied solid and undrilled. Choose a suitable drilled bung and airlock for active fermentation rather than using a solid stopper to close a gas-producing vessel.
