Will this capsule run on your machine?

Pick the machine and the size, enter what you measured if you have measured it, and you get the published envelope for that size across the makers, whether your capsule sits inside it, the body inner diameter your pin or nozzle has to clear, the closed-length change against your current setting, and the parts to gauge before the trial. Nothing you enter leaves this page.

The Capsule Machine Fit AI Prompt Pack takes this further. It builds the twenty-capsule measurement log, compares the new maker's sheet to the one you run now, writes the trial protocol with rejects counted by station, and drafts the change record for your quality system. Get the pack, or reply to any email from us and ask for a fit sample with its specification sheet.

Envelope figures are the published nominal dimensions from the capsule makers' own specification sheets as of September 2026, lowest to highest across makers, from the article above. Tolerances used for the verdicts are the widest a maker states (±0.06 mm on diameter, ±0.4 mm on closed length). Wall thickness nominals are one large maker's published body figures. The checker is a starting point for a trial run, not a substitute for one. Nothing here is advice about what a capsule's contents do for anyone.
