Where are O-ring cords used?

O-ring cords are commonly used on non-moving machinery and static sealing applications to keep air, other gases, and liquids from passing in or out of any given area. They are especially prevalent in pneumatic and hydraulic systems. O-ring cord has a clear advantage for fitting seals to special dimensions that standard stock O-rings may not cater to.

The standard extruded cord is produced to tolerances according to the Standard ISO 3302-1.
