GP6400-04-04-04FP Tompkins JIC-to-O-Ring Gauge Port, -04 Female Pipe Port

Within Tompkins' pressure-test fitting range, GP6400-04-04-04FP provides a JIC-to-O-ring path and a dedicated -04 female pipe port in one gauge-port configuration. At the gauge connection, Tompkins calls out 1/4-18 female pipe. That is the detail most likely to separate this part from another GP6400 model with the same 04/04 primary sizing.

GP6400 is selected when the primary fitting must transition between JIC and O-ring styles while still providing gauge access. This 04/04 configuration is one of the more compact nominal-size choices in the family.

If the same 04/04 primary sizes are needed with the SAE O-ring gauge-port style, the corresponding alternate part is GP6400-04-04-04FB. Before ordering, compare the family, both nominal sizes, and the third-port thread with the fitting already on the equipment.
