GP2403-12-12-04FP Tompkins JIC-to-JIC Gauge Port, -04 Female Pipe Port

The GP2403-12-12-04FP gauge port is built around male JIC connections on both primary positions, with nominal sizes 12 and 12 and a separate gauge connection. This GP2403 layout is the fixed JIC-to-JIC option in the Tompkins gauge-port range.

The 12/12 pairing sits in the middle of the available nominal-size range, making the part number itself important when comparing adjacent sizes. The gauge takeoff is threaded 1/4-18 female pipe. That thread should be checked separately from the two primary fitting sizes, because the SAE O-ring version of the family uses a different third-port connection.

If the same 12/12 primary sizes are needed with the SAE O-ring gauge-port style, the corresponding alternate part is GP2403-12-12-04FB. Before ordering, compare the family, both nominal sizes, and the third-port thread with the fitting already on the equipment.
