GP6504-12-12-04FP Tompkins JIC Swivel Gauge Port, -04 Female Pipe Port

Within Tompkins' pressure-test fitting range, GP6504-12-12-04FP provides a JIC swivel 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 GP6504 model with the same 12/12 primary sizing.

GP6504 is the swivel option in this group, using a male JIC connection opposite a female JIC swivel. At nominal size 12 on both primary connections, this version occupies the mid-range of the family rather than either size extreme.

If the same 12/12 primary sizes are needed with the SAE O-ring gauge-port style, the corresponding alternate part is GP6504-12-12-04FB. Before ordering, compare the family, both nominal sizes, and the third-port thread with the fitting already on the equipment.
