The chain is fine...but I ordered the wrong size. Nine links of the chain I ordered equals six of the size I wanted. My error...
How can I straighten out the springs? I can't use them coil uo as is.

☕ Whether you're pulling your morning shot or dialing in a new single-origin roast, the right filter basket makes all the difference. These 304 stainless steel espresso baskets are built for semi-automatic portafilter machines and come in three common sizes — 51mm, 54mm, and 58mm — so you can find the perfect fit for your setup. Designed with precision-etched holes, they help you achieve a balanced extraction with rich crema, reducing common issues like channeling or uneven flow. If you're a home barista tired of inconsistent shots, upgrading to a durable, food-grade steel basket is a small change that solves a big problem.

| Dose Markings Note | Gram numbers on the basket are size specs, not absolute capacity — actual yield depends on grind size and roast level. |
Spritzing is typically caused by uneven distribution of coffee grounds, incorrect grind size, or inconsistent tamping — it's not a defect in the basket. Try adjusting your grind finer, using a distribution tool, and tamping evenly. Switching to a precision basket like this one can actually help reduce channeling, but proper puck prep is still key.
The number (e.g., 18g or 20g) indicates the nominal dose specification for that basket size, not the exact capacity. The actual amount of coffee you can dose depends on the bean's density, roast level, and grind size. Feel free to dose a gram more or less to dial in your perfect shot.
Measure the inner diameter of your portafilter where the basket sits. If it matches 51mm, 54mm, or 58mm (slightly under is normal), this basket will fit. Most home semi-automatic machines use one of these three sizes. If you're unsure, check your machine's manual or measure with a ruler before ordering.
No. Made from genuine 304 food-grade stainless steel, it's highly resistant to corrosion. To keep it in top shape, simply rinse and dry after use — avoid harsh detergents or soaking in undissolved descaling powder, which can affect any stainless surface.
With regular home use, a quality 304 stainless basket can easily last several years. However, if you notice persistent extraction issues (uneven flow, visible wear, or clogged holes that can't be cleaned) — or after approximately 3,000 shots — it's a good idea to replace it. A fresh precision basket restores consistency.
Yes! These baskets are fully compatible with bottomless (naked) portafilters of the matching diameter. In fact, the precision hole pattern makes them an excellent choice for diagnosing your extraction and improving your technique.
