GP6504-10-10-04FP Tompkins JIC Swivel Gauge Port, -04 Female Pipe Port

Tompkins part GP6504-10-10-04FP pairs a JIC swivel body with nominal sizes 10 and 10, then adds a -04 female pipe port as the gauge connection. On GP6504, one side is a male JIC connection and the other is a female JIC swivel; Tompkins specifies steel construction.

At nominal size 10 on both primary connections, this version occupies the mid-range of the family rather than either size extreme. Because Tompkins offers parallel FP and alternate-port versions, the third connection deserves its own fit check. On GP6504-10-10-04FP, it is 1/4-18 female pipe.

If the same 10/10 primary sizes are needed with the SAE O-ring gauge-port style, the corresponding alternate part is GP6504-10-10-04FB. Confirm all three connection points against the installation rather than substituting solely on the basis of the GP6504 family name.
