Ask A Question

Description & Features

Manufactured from steel, this 9/16-18 Male SAE O-Ring Boss (Straight Thread O-Ring) Hex Plug from Eaton Aeroquip is designed to seal hydraulic ports using a straight thread O-ring connection, providing a reliable, leak-resistant closure in high-demand fluid power systems.

Catalog number C1CB12, this fitting is suited for use across marine and military, chemical processing, pulp and paper, food and beverage processing, and offshore drilling applications, environments where connection integrity under pressure is critical.

The straight thread O-ring boss design seats against the port face rather than relying on thread deformation, making it a preferred choice for systems requiring consistent, repeatable sealing performance.
