Frequently Asked Questions

Erie, PA USA. Our Mason jar lids are made start to finish from design, manufacture and fulfillment!

No. reCAP makes the caps, lids, and accessories that make Mason jars more useful, but we do not manufacture the glass jars themselves. “Mason” is a type of jar, not a single brand. If your question is about a jar itself, or a jar that broke, the best place to start is the store where you bought it, or the jar maker: Ball, Kerr, and Golden Harvest jars are made by Newell (freshpreserving.com), and other makers include Anchor Hocking and Libbey.

The reCAP Mason jar lids are specifically designed to be BPA/BPS-free, freezer-proof and dishwasher safe. Made of FDA-approved BPA/BPS-free number “5” Polypropylene plastic. While it is not the organically-derived (i.e. plant/bio-based) plastic typically used in disposable products, it is recommended as the safest choice for food and beverages.

reCAP® Mason jar lids fit regular mouth Mason Jars (2.5″ or 70mm continuous thread) and wide mouth Mason Jars (3″ or 86mm continuous thread). Not all jars that have “Mason” embossed on them are the standard size or screw thread. Also be mindful, jar volume does not determine the mouth size of the jar.

The original wide-mouth POUR Mason jar lid has a quick release flipper. It is easy to remove and replace.

We believe in giving back and we're passionate to make the world a better place. As part of our company planning process we make yearly commitments to specific organizations.

Silicone.

The waterless airlock is a one-way valve. It allows gases or liquids to flow in only one direction. The purpose of the airlock is to allow carbon dioxide gas to flow out of the jar and prevent oxygen (or anything else) from flowing into the jar.

We recommend cleaning the airlock by hand with mild soap. Since it's a one-way valve, water will only flow in the direction of the arrow on the airlock. Make sure to run water through the airlock to get all the soap out.

Unlike most other fermentation products, reCAP includes a low-profile, waterless airlock. Some of the benefits are:

1. No need to monitor the water level.
2. The 3-piece airlock is made from a brittle plastic that can easily break. The reCAP fermenter is almost indestructible.
3. The reCAP fermenter is much easier to clean.
4. The reCAP fermenter is a much lower profile, therefore it better fits on shelves.

In addition, there are many uses for a waterless airlock! It can be used to store your coffee to keep fresh, brew small batches of beer, and more.

First make sure that there is a gasket inside and it is lying flat. Then make sure the lid is threaded straight on the jar (not askew) and tighten. Double check the fit is tight! Some Mason jars may not successfully seal due to severe variations. Older Mason jars especially may have been altered or are non-standard. Since these will not be 100% leak-proof on every jar variation, keep in mind that they are also great for dried goods and pantry items as well!

No, reCAP® Mason jar lids and most plastic are not to be used in canning or microwaving.

Yes. While it is not recommended to heat plastic, reCAP® POUR Mason jar lids can be washed on the top rack of dishwashers. Hand-washing with a mild soap is preferred and recommended to extend the lid's life.

Independent lab testing shows that the lids are stain resistant.

Yes, gaskets are easy to clean by hand or in the top rack of a dishwasher. We also sell replacement gaskets if needed.

The gasket is meant to fit snugly in the channel on the underside of the lid. Press it in evenly on four sides, like an X, then press the spots in between. Do not drag your finger around the channel, that stretches the silicone and makes it bubble. Then screw the lid on slowly so the gasket seats without stretching. Watch: how to put a gasket in a reCAP lid.

Remove the gasket, wash it by hand, and let it air dry fully before putting it back. This matters most after fermenting or green smoothies. Our silicone gaskets resist mold and mildew, and you can buy replacement gaskets whenever one wears out.

Sometimes lids can be a little stubborn. Try using the pour spout as leverage with your thumb and opening the flip lid to reduce potential vacuum pressure. If it's still a little tricky, fill the jar with hot water and let it sit upside down for a minute before trying to remove the lid. New gaskets can also be purchased if the gaskets are worn.

If the flipper lid is difficult to close or open, try adding a drop of cooking oil on your finger-tip and lubricating around the edge/sides of the closure. You should only have to do this one time, and the problem will be resolved, even after washing the cap.

In a lab test it was determined that our caps are dishwasher safe and can withstand the effects of extreme temperature change of 0°F and 120°F.
