Frequently asked

Is a fluorocarbon O-ring suitable for phosphate-ester hydraulic fluid?

Generally not. Fluorocarbon elastomers are not recommended for phosphate-ester fluids such as Skydrol. Use the seal the component manual specifies for the system fluid.

What does the dash number on an AS3209 O-ring mean?

It identifies the size of the ring, its inside diameter and cross-section, as listed in the standard.
