Generic Buna-N O-Ring [7-1/4" ID] [1/8" CS] (O-242)

A Buna-N O-ring helps create a dependable seal at a compatible large circular connection, and this generic version is sized with a 7-1/4 inch inside diameter and 1/8 inch cross-section using the O-242 reference. When an O-ring in this profile becomes cut, worn, or compressed, the assembly can lose the sealing support it should maintain.

The 1/8 inch cross-section gives this O-ring practical value because it provides a balanced sealing profile for larger groove designs that do not require a heavier-duty section. A properly selected O-ring helps support cleaner compression and contributes to more dependable sealing performance in the intended application.

This type of part is especially useful during service work where both larger inside diameter and exact profile need to match the original seal closely. That makes replacement more accurate and more dependable.

Installed in the proper application, this O-ring helps support dependable sealing and contributes to cleaner overall system integrity.
