GP2403-24-24-04FB Tompkins JIC-to-JIC Gauge Port, -04 SAE O-Ring Port

GP2403-24-24-04FB is not just another GP2403 gauge port; it is the exact 24/24 nominal-size version using the FB gauge-port configuration.

Tompkins specifies the third connection as 7/16-20 female O-ring. Matching that gauge-port thread prevents confusing this FB version with the otherwise similar female pipe configuration. Both primary connections are nominal size 24, making this one of the largest configurations in the series.

With GP2403, both main connections are male JIC; the separate third port is reserved for the gauge connection.

Use the structured specifications to verify that the primary sizes and gauge-port style match the existing connection.
