Tygon vinyl tubing (E-3603 / S3 E-3603): ID × OD × wall, 1/32 to 1 in ID, 1/16 to 1/4 in walls — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/tygon-vinyl-tubing-e-3603-sizes/ (sheet CC BY 4.0) Basis: Saint-Gobain Tygon E-3603 datasheet as hosted by Novatech USA (30 sizes), cross-checked against Thomas Scientific's 21-item Tygon S3 E-3603 listing; numbers only; pressure ratings left out Catalog version: 2026-10-20 Sizes: see table below - Tygon E-3603 is the clear flexible laboratory tubing that 'Tygon-type' and 'clear vinyl tubing' refer to (one retailer lists it as 'Special PVC'; the datasheet says clear, flexible, BPA- and phthalate-free); Thomas Scientific lists Tygon S3 E-3603 as non-DEHP tubing in the same ID × OD sizes. It is sized as ID × OD in inches (1/4 × 3/8 in is a 1/16 in wall; 1/4 × 1/2 in is a 1/8 in wall); the wall is (OD − ID) ÷ 2 and was checked against every wall the datasheet prints (3/32 in = 0.09375, 1/8 in = 0.125, 5/32 in = 0.15625 ... agree). - 30 sizes from the Novatech-hosted datasheet: 1/32 × 3/32, 1/16 × 1/8, 1/16 × 3/16, 3/32 × 5/32, 3/32 × 7/32, 1/8 × 3/16, 1/8 × 1/4, 5/32 × 7/32, 3/16 × 5/16, 3/16 × 3/8, 1/4 × 3/8, 1/4 × 7/16, 1/4 × 1/2, 5/16 × 7/16, 5/16 × 1/2, 5/16 × 9/16, 3/8 × 1/2, 3/8 × 9/16, 3/8 × 5/8, 7/16 × 9/16, 1/2 × 5/8, 1/2 × 11/16, 1/2 × 3/4, 1/2 × 13/16, 5/8 × 13/16, 5/8 × 7/8, 3/4 × 1, 3/4 × 1-1/8, 1 × 1-1/4, 1 × 1-1/2 in. Thomas Scientific's S3 E-3603 listing has 21 items (20 distinct sizes, one listed in two lengths); the 16 that are also in the datasheet agree on ID, OD and wall for every row. Thomas adds 7/16 × 11/16 (a 1/8 in wall), which is not in the Novatech datasheet and is shown with Thomas as the only source. Three more Thomas rows (3/4 × 1 1/16, 1 1/4 × 1 1/2, 1 1/2 × 2) print walls that cannot be right (2 3/4 in, 7 7/8 in, 5 7/8 in) and are left out. - Metric equivalents of the same tubing (for example 6.4 × 0.8 mm walls listed by retailers) were not read from the maker and are not copied. Maximum pressures in the datasheet are left out on purpose, and the datasheet states no temperature range. Tubing for other fluids: silicone-tube-and-fittings, nylon-tubing-inch-metric-sizes, polyethylene-tubing-lldpe-sizes, ptfe-fep-pfa-tubing-fractional-sizes. Hose barbs and push-fit: silicone-tube-and-fittings. No files: tubing is not drawn as a fixed shape.
