Champion CA409 Imperial O-Ring Splicing Assortment Kit

O-rings are the most widely used sealing element in hydraulic, pneumatic, and fluid systems — providing a reliable seal in static and dynamic groove applications. Part number CA409. Champion O-rings are available in nitrile (NBR) for general oil and fuel applications, with an extensive size range in both metric and imperial series.

Where this tool is used

• Static and dynamic sealing in hydraulic cylinders, pneumatic actuators, valves, pump housings, and fluid system connectors requiring a reliable compression seal.
• General maintenance and workshop applications.

Selecting the right option

Match the O-ring cross-section (C/S) and inside diameter (I/D) to the groove dimensions — check both metric and imperial series for your application. Nitrile (NBR) is the standard choice for petroleum oils and hydraulic fluids; specify Viton (FKM) for elevated temperatures or aggressive chemical contact.
