The Fabco 999-10003 or 99910003 is a threaded cap plug sized for a 9/16-18 thread, designated as a #6 OR (O-ring) port. This type of plug is used to seal hydraulic or pneumatic ports on heavy-duty driveline and transfer case components where a fitting or line is not installed. The 9/16-18 thread size and #6 O-ring face seal designation make it a specific, non-interchangeable fit, so confirming the thread and port type on your application before ordering is important. Sold by Pro Gear and Transmission. Call us to confirm this is the correct plug for your port configuration.
