Corrections to chart values

If you spot a value that does not match a manufacturer's published data, please include the fitting size, the value you expected, and the source (for example a catalog name and page). Every correction is checked against published references before the site is updated.

What we can't help with

• We don't sell fittings, hoses or tools, and we can't provide quotes or product recommendations.
• We can't diagnose a specific machine or confirm that a part is safe for a specific application. Please contact the equipment or fitting manufacturer for that.
