GP6504-32-32-04FB Tompkins JIC Swivel Gauge Port, -04 SAE O-Ring Port

GP6504-32-32-04FB is the 32/32 nominal-size member of Tompkins' GP6504 family, combining a JIC swivel fitting layout with a dedicated -04 SAE O-ring port for pressure-gauge access.

The GP6504 family adds a female JIC swivel to the primary connection path, paired with a male JIC connection. 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.

Both primary connections are nominal size 32, making this one of the largest configurations in the series.

The specification table below provides the final check for family, gauge-port type, and both nominal connection sizes.
