How does the stainless steel frame of Le Parfait jars work? Essential for successful home canning

🔩 One metal clip, a thousand uses

When we talk about Le Parfait jars, we immediately think of their iconic silhouette: the mechanical closure jar , also called a stainless steel frame jar . This small stainless steel element, also called a strap , clip or metal closure , is far from being a simple aesthetic detail. It is this which guarantees the jar's watertightness, durability and reusability.

At Amphitria , we're passionate about simple, sustainable, and meaningful actions. Making your own homemade preserves with the right tools is an essential part of that. That's why we offer you Le Parfait Super jars , with their famous stainless steel frame, in complete transparency.

What is a stainless steel jar mount?

The stainless steel frame , or metal clip , is the hinged stainless steel frame that surrounds the lid of the jar. It allows the jar to be hermetically sealed using a rubber seal . This mechanical closure is typical of Le Parfait jars , which have been popular for generations with lovers of canning, fermentation, and bulk foods.

It is a reusable, heat-resistant system, compatible with sterilization in a pressure cooker, electric sterilizer or bain-marie.

How does this metal closure work?

It's simple, but incredibly effective:

1. We fill the jar (vegetables, fruits, cooked dishes, sauces, etc.).

2. Place the rubber seal on the lid.

3. We close the metal or glass cover depending on the model.

4. We lower the stainless steel clip , which applies strong and regular pressure.

5. After sterilization, the air vacuum is created naturally , ensuring long-term preservation.

👉 Result: a perfectly sealed jar, without leaks or contamination.
👉 Another advantage: the mechanical closure can be opened and closed endlessly (you just need to change the seal each time you sterilize it).

Why choose a Le Parfait jar with a stainless steel frame?

✅ Robustness

The stainless steel frame is resistant to oxidation, dishwasher, sterilizer, and time. Unlike other zinc-plated iron systems, it does not rust and hardly wears out.

✅ Zero plastic, zero screws

No screw-on lid, no plastic. It's a 100% mechanical system , which doesn't rely on any threads or plastic seals.

✅ Easy to open

Once the air vacuum is broken (by pulling on the seal tab), opening is easy, without forcing, even after several months.

✅ Perfect for home preservation

Compotes, ratatouilles, onion confits, pickles, tomato sauces... The stainless steel frame guarantees safe, long-lasting and healthy storage .
