GP6504-06-06-04FB Tompkins JIC Swivel Gauge Port, -04 SAE O-Ring Port

If the existing plumbing uses Tompkins' GP6504 JIC swivel pattern, GP6504-06-06-04FB is the version sized 06/06 with a -04 SAE O-ring port.

The swivel geometry distinguishes GP6504 from the fixed JIC-to-JIC designs. Tompkins lists the fitting material as steel.

Primary fit is determined by the 06 and 06 nominal sizes, while the gauge side is determined by the 7/16-20 female O-ring third-port thread.

This 06/06 configuration is one of the more compact nominal-size choices in the family. Because several GP6504 models share the same basic shape, use the part number and connection data below as the final fit check.
