O-Ring Size Identifier
AS568 Imperial is pre-selected because most hydraulic O-rings in Australia are commonly ordered by dash size. Choose from standard sizes shown in mm and inches, then get the dash size, physical measurements and closest equivalent.
Step 1 — Select Standard
Tip: In Australian hydraulics, AS568 dash sizes such as -214 are usually the easiest way to order O-rings from seal suppliers.
Step 2 — Select Application
Step 3 — Select Measurements
Dropdowns use standard listed sizes to reduce ordering mistakes. Old O-rings may be swollen, stretched or flattened, so always verify before ordering.
