GP6400-04-04-04FB Tompkins JIC-to-O-Ring Gauge Port, -04 SAE O-Ring Port

For buyers replacing an existing gauge-port fitting, GP6400-04-04-04FB matches a JIC-to-O-ring arrangement with 04 and 04 nominal connections.

The GP6400 family is the JIC-to-O-ring branch of the range, pairing a JIC connection with an O-ring connection on the main fitting path.

Tompkins identifies the gauge side as 7/16-20 female O-ring; that third-port specification is independent of the nominal sizing on the main flow path.

This 04/04 configuration is one of the more compact nominal-size choices in the family. The specification table below provides the final check for family, gauge-port type, and both nominal connection sizes.
