GP6504-06-06-04FP Tompkins JIC Swivel Gauge Port, -04 Female Pipe Port

GP6504-06-06-04FP belongs to the GP6504 gauge-port line and is distinguished by a 06/06 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.

On GP6504, one side is a male JIC connection and the other is a female JIC swivel; Tompkins specifies steel construction. This 06/06 configuration is one of the more compact nominal-size choices in the family.

If the same 06/06 primary sizes are needed with the SAE O-ring gauge-port style, the corresponding alternate part is GP6504-06-06-04FB. Match the 06/06 primary sizing first, then confirm the gauge-port thread shown in the specifications.
