O-ring Groove Design in 3 easy steps:

Step 1

Choose whether you are working with existing hardware or designing new hardware.

Select the type of O-ring groove - piston, rod, face seal or trapped seal.

If the O-ring size required is known, simply select the AS, BS or ISO standard (such as AS568) and enter the dash size reference.
If the O-ring size is unknown, input the nominal bore/rod diameter of your hardware in inches or mm.

Step 2

If you are looking for standard O-ring sizes to fit existing hardware a list of suitable BS, AS and ISO standard O-ring sizes is displayed.  
Simply select the size which best meets the application requirements based on O-ring cross section from the list.
