THE PROBLEM WITH METRIC CYLINDERS

The Problem with Metric Cylinders

We have noticed a company or two that are attempting to sell aluminum bodied metric cylinders imported from China.  We want to make our customers aware that there are several reasons that these should be avoided:

  • The shaft and mounting threads are metric making it difficult to find parts 
  • The mounting hardware is made very cheaply from thin-walled steel
  • The bore size is in metric but a conversion is done to imperial to make them seem "standard"
  • The body of the cylinder is constructed from thin-walled aluminum which can burst or fall apart
  • The air port thread sizes are usually imperial (but sometimes also metric)

* Imperial: Measurement standard used in the USA.  Inches ("), feet ('), and yards (yd) are all Imperial.  Fractions such as 1/4", 1/2" 3/4" are also Imperial.

* Metric: Measurement standard used in most other parts of the world.  Millimeters (mm), centimeters (cm), and meters (m) are examples of metric sizes.
