Ball Leak-Proof Plastic Lids for Regular Mouth Mason Jars (6-Pack)

My Favorite Lids for Yogurt-Making (and So Much More)

If you've been dabbling in homemade yogurt, you know the container matters. These lids? They're the unsung heroes of my yogurt setup.

Unlike the metal two-piece lids that rust or warp in the sous vide, these plastic screw-on lids are leak-proof, rust-free, and beautifully boring — in the best way. They just work. Tight seal, no drips, and easy to open even with one hand.

I use them every week for jars of yogurt, but also for chia pudding, salad dressing, nut milks, and anything I want to stash without drama. They survive dishwashers, hot water baths, toddlers, and the occasional fridge avalanche.


Why I Keep Reordering These

  • Leak-proof — ideal for yogurt, broth, or anything sloshy
  • Rust-free plastic — no weird flavors, no maintenance
  • Easy screw-on design — no fiddling with rings or seals
  • Works with all regular-mouth jars — versatile and dependable
  • Dishwasher and microwave safe — cleaning is a breeze

👩‍🔬 For fermentation, storage, or your daily chia pudding ritual — these lids have earned their spot in the drawer.

Unlike some off-brand versions, the Ball lids are reliably leak-proof, durable, and easy to clean (dishwasher safe, of course). And they don’t warp over time — even after many batches of bubbling, steaming, gut-happy food.

When You're Ready to Upgrade from "Good Enough"

There are a dozen ways to keep your ferment under the brine.
A cabbage leaf. A scrubbed rock. That small glass ramekin that always tips.

But when you're done improvising and ready for something that just works — beautifully — these weights are it.

Masontops didn’t just make a hunk of glass.
They designed these Pickle Pebbles to fit wide-mouth jars exactly, with just the right weight to hold things down, and a clever little grip that makes you feel like someone thought this through.

They’re not the only good option out there — but if you want something that lasts, looks great, and makes your life easier?
This is the set I’d point you to.


What I Love:

  • Crystal-clear, non-porous glass — no stains, smells, or weirdness
  • Fits like a glove in wide-mouth Mason jars (2.7” diameter)
  • Flat, heavy, stable — keeps things properly submerged
  • Built-in finger grip — no more fork-fishing or jar-tilting
  • Top-rack dishwasher safe — and honestly, they still look brand new after dozens of batches

🥒 These are the weights I pull out when I want the whole process to feel smooth, clean, and just... better.

What Are Pickle Pipes?

Pickle Pipes are silicone lids designed to fit onto mason jars, allowing gases produced during fermentation to escape while preventing oxygen from entering. This creates an ideal environment for fermenting vegetables like sauerkraut, pickles, and kimchi without the need for daily "burping" of jars.

Compatibility

Pickle Pipes are available in two sizes:

  • Regular Mouth (Small): Fits mason jars with a 2.75-inch (7 cm) diameter opening.
  • Wide Mouth (Large): Fits mason jars with a 3.38-inch (8.6 cm) diameter opening.

Ensure you select the correct size for your jars to achieve a proper seal.

Features

  • One-Way Valve: Automatically releases fermentation gases while blocking oxygen.
  • Low Profile: Compact design makes storage easy, even in tight spaces.
  • Food-Safe Silicone: Made from BPA-free and phthalate-free materials.
  • Dishwasher Safe: Easy to clean and reuse.

Usage Tips

  • Activation: Before first use, pinch the valve to ensure it's open.
  • Storage: Store lids flat to prevent warping.
  • Weights: For best results, use with fermentation weights to keep vegetables submerged.

Considerations

  • Overflow: During active fermentation, some brine may escape. Place jars on a tray to catch any spills.
  • Odor Absorption: Silicone can absorb strong odors over time. Regular cleaning can help mitigate this.

Customer Feedback

Users appreciate the simplicity and effectiveness of Pickle Pipes. They find them especially helpful for small-batch fermenting and note that the low-maintenance design makes the fermentation process more accessible.


Note: Always ensure you're using the correct size lid for your mason jars to maintain an airtight seal during fermentation.

Masontops Pickle Pipes – Waterless Airlock Fermentation Lids (Wide Mouth, 8-Pack)

Low-maintenance lids for your low-key fermenting life.

These soft silicone Pickle Pipes take the stress out of mason jar fermenting. They’re self-venting, waterless, and surprisingly discreet (you won’t bonk them on the cabinet when closing the door). Just pop one on a jar, press the center to open the valve, and let the gases escape while keeping the bad stuff out.

They’re especially great for wide-mouth mason jars—and for people who'd rather not hover over their kraut like an overprotective parent.

Why I Keep Using These

  • Made for wide-mouth mason jars (Ball, Kerr, etc.)
  • Airlock magic: lets gas out, keeps oxygen and dust away
  • No burping, no babysitting
  • Just ½" tall — perfect for countertop or cupboard ferments
  • Food-safe silicone (BPA-free, phthalate-free)
  • Dishwasher safe, low-drama cleaning

Little Things to Love

  • Comes in four mellow colors — helpful if you’re running a kraut rainbow
  • Great for ferments with higher gas production (like kimchi or garlic)
  • Won’t roll off the counter (yes, we’ve tested this)

Note: This is the wide-mouth set. If you’re using regular (a.k.a. small-mouth) jars, check out the other version!
