GP6504-24-24-04FP Tompkins JIC Swivel Gauge Port, -04 Female Pipe Port

The connection geometry on GP6504-24-24-04FP is the key: a male JIC connection paired with a female JIC swivel, plus a dedicated gauge port specified separately from the main fitting path. 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.

On GP6504, one side is a male JIC connection and the other is a female JIC swivel; Tompkins specifies steel construction. The 24/24 nominal sizing places this model at the large end of the family.

If the same 24/24 primary sizes are needed with the SAE O-ring gauge-port style, the corresponding alternate part is GP6504-24-24-04FB. Confirm all three connection points against the installation rather than substituting solely on the basis of the GP6504 family name.
