Why this preserve jar earns its place
These clamps work with rubber washers (sold separately, item GH389) to lock Weck jars shut with an airtight seal. Stainless steel construction means they won't rust or corrode even in a busy commercial kitchen environment or after repeated dishwasher cycles. The small size — just 35mm tall — means you can use them on standard Weck jar lids without needing oversized equipment or extra workspace.
One pack gives you eight clamps. If you're setting up an in-house jarring operation or bottling programme — sauces, preserves, coulis, infused oils — you'll need one clamp per jar. The dishwasher-safe design survives high-temperature wash cycles without degrading.
The clamp-and-washer system is reliable: it's the method Weck jars use across European kitchens. Once sealed properly, the jar stays preserved. The clamps stay in place until you deliberately release them.
