GP2403-16-16-04FP Tompkins JIC-to-JIC Gauge Port, -04 Female Pipe Port

GP2403-16-16-04FP belongs to the GP2403 gauge-port line and is distinguished by a 16/16 primary size pairing together with its -04 female pipe port. The gauge connection is 1/4-18 female pipe. If the mating gauge or test hardware uses the other port style, the corresponding alternate model should be selected instead.

The underlying GP2403 fitting remains JIC-to-JIC, so the gauge takeoff is added without changing the primary connection type. The matching 16/16 nominal sizing puts this model toward the larger half of the family.

If the same 16/16 primary sizes are needed with the SAE O-ring gauge-port style, the corresponding alternate part is GP2403-16-16-04FB. Match the 16/16 primary sizing first, then confirm the gauge-port thread shown in the specifications.
