GP2403-12-12-04FB Tompkins JIC-to-JIC Gauge Port, -04 SAE O-Ring Port

For a 12-to-12 nominal-size connection that also needs a gauge takeoff, GP2403-12-12-04FB is the corresponding Tompkins GP2403 configuration.

The two main connection sizes do not tell the whole story. This model's gauge port is 7/16-20 female O-ring, which defines the third connection. This model uses matching nominal size 12 connections on the primary path; nearby part numbers step that size up or down.

The GP2403 family keeps the main path JIC-to-JIC, using male JIC connections at both primary positions.

The specification table below provides the final check for family, gauge-port type, and both nominal connection sizes.
