Notes
- Polyethylene tubing is sold by OD with the ID set by the wall; the sizes read are Freelin-Wade's linear low-density polyethylene (LLDPE) line: 1/8 in OD (0.062 ID, 0.031 wall), 5/32 (0.106, 0.025), 1/4 (0.170, 0.040), 5/16 (0.187, 0.062), 3/8 (0.250, 0.062), 1/2 (0.375, 0.062), 5/8 (0.500, 0.062), 3/4 (0.625, 0.062) and 3/4 × 0.500 (0.125 wall) in; metric 4 × 2.7, 6 × 4, 8 × 6, 10 × 8 and 12 × 9 mm. The catalog page says Freelin-Wade no longer offers low-density polyethylene (LDPE). 'Poly tubing' for drip irrigation is sold in similar ID × OD sizes: drip-irrigation-tubing-sizes.
- Liquiflex POE (polyolefin, listed separately) is 1/4 in OD × 1/8 in ID (0.062 wall) and 3/8 in OD × 0.245 in ID (0.062 wall). Each ID and wall was checked against OD − 2 × wall: the LLDPE rows agree to within 0.004 in (0.1 mm for the metric rows); the POE 3/8 in row does not quite (3/8 − 2 × 0.062 is 0.251 in against the printed ID 0.245 in), and both printed values are shown.
- Bend radius is shown (inches, as printed) for the inch LLDPE and POE rows; the datasheet's metric bend radii are not copied (printed without units, in the text read). Working pressures at 75 °F and 150 °F and part numbers are left out. Other tubing: nylon-tubing-inch-metric-sizes, tygon-vinyl-tubing-e-3603-sizes, ptfe-fep-pfa-tubing-fractional-sizes, silicone-tube-and-fittings. No files: tubing is not drawn as a fixed shape.
