Olypsys: O-Ring & Part Sizing

Measure and identify O-rings, hydraulic seals, gaskets, screws, bolts, circlips, and washers from a single phone photo. A dimension is not an answer. A part number is an answer. Squeeze a caliper on a soft rubber O-ring and the reading shrinks. Pull a chewed-up seal out of a machine and it is no longer the size it started as. With Olypsys, you lay the part flat on a calibration grid, tap Measure, and get exact dimensions plus ranked part numbers across international standards in seconds. Users have measured over 100,000 parts with it. TRY IT FREE IN 2 MINUTES Print a free A4 or US Letter calibration grid right from the app on any office printer (includes 30 free printed-grid measurements plus free feature previews). Measure parts every week? Order a factory pre-calibrated A4 or A3 Pro Grid: just scan the QR code and measure with zero manual setup and unlimited basic O-ring measurements. WHY IT BEATS CALIPERS, CONES & THREAD GAUGES • Zero contact squeeze: Never compresses soft elastomers or flexes thin retaining rings. • Ellipse fitting, not forced circles: A flexible O-ring on a table is rarely a true circle. Olypsys traces the full inner and outer edges independently, and measures up to 1,500 mm (59") ID on large-format grids. • Wear & compression-set compensation: Pull a nicked, torn, or flattened seal out of a cylinder and Wear Compensation reconstructs the original undamaged dimensions so you order the right replacement. • Sub-0.01 mm repeatability: 8–9 µm (0.008–0.009 mm) ID repeatability on Pro Grids, with automatic correction for camera angle, lens distortion, and shadows. WHAT YOU CAN MEASURE & IDENTIFY Free = included with a printed grid (30 measurements) or Pro Grid • Preview = try before you buy • Pro = full access with a Pro subscription. • O-Rings (Free & Pro): Standard O-rings, worn/compression-set seals, translucent FEP/PTFE-encapsulated rings, and multi-ring batch captures. • Hydraulic & Pneumatic Seals (Preview): Guided 3-angle capture and 3D cross-section fitting measures ID × OD × Height, ranks 24 profile classes (U-cups, rod & piston seals, wipers/scrapers, buffer seals, wear bands, rotary shaft seals), and matches against 30,184 catalog parts. • Gaskets & 2D Profiles (Preview / Pro): Lay a flange or housing gasket on the grid and get a constraint-fitted CAD profile (true arcs, lines, and bolt circles) in about a second, ready to export as DXF or SVG for cutting or quoting. • Screws, Bolts & Threads (Preview / Free): Measures major and root diameter, thread pitch (mm) or TPI, head across-flats, and length; matches 646 standards across 23 thread families. • Circlips, Snap Rings & Washers (Pro): Measures unstretched free diameter (d3), gap, and band width and matches directly to nominal shaft or bore size. • X-Rings, Square Rings & Backup Rings (Pro): Purpose-built edge detection for four-lobed Quad Rings and rectangular anti-extrusion backup rings. BUILT-IN INTERNATIONAL STANDARDS • O-Rings & Seals: AS568 (-001 to -449+), ISO 3601, BS 4518, BS 1806, GB/T 3452.1, JIS B 2401 (P, G, V, S), DIN 3771, SMS 1586, and metric tables. • Gaskets: ASME B16.21 and EN 1514-1 flange standards (DN10–DN800). • Screws & Fasteners: ISO Metric coarse/fine, UNC/UNF/UNEF, BSW/BSF, BA, BSPP/BSPT, NPT, wood, and self-tapping. • Circlips: DIN 471, DIN 472, DIN 983/984, DIN 6799, JIS B 2804, and DIN 7993/9925/9926. CAD EXPORT, 3D MODELS & CLOUD HISTORY (THE VAULT) • Export traced gaskets, circlips, or washers as DXF, SVG, or .o2d, or refine them in the browser 2D sketch editor at app.olypsys.com. • Inspect measured screws as interactive 3D helical models. • Instant Pass/Fail checks against standard tolerances and one-click PDF inspection reports or Excel logs.
