GP2403-20-20-04FB Tompkins JIC-to-JIC Gauge Port, -04 SAE O-Ring Port

On GP2403-20-20-04FB, Tompkins combines the JIC-to-JIC fitting path with a third connection specifically for the pressure gauge.

The GP2403 family keeps the main path JIC-to-JIC, using male JIC connections at both primary positions. The FB designation matters here: this model's gauge takeoff is 7/16-20 female O-ring, not the female pipe style offered elsewhere in the same family.

With both primary connections at nominal size 20, this version is intended for the larger connection sizes offered in the series.

Review the nominal sizes and gauge-port thread together before treating another GP2403 part number as interchangeable.
