GP2403-08-08-04FB Tompkins JIC-to-JIC Gauge Port, -04 SAE O-Ring Port

Choose GP2403-08-08-04FB when the fitting layout calls for Tompkins' GP2403 JIC-to-JIC geometry with matching 08/08 nominal sizes and a -04 SAE O-ring port.

The GP2403 family keeps the main path JIC-to-JIC, using male JIC connections at both primary positions.

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.

At nominal size 08 on both primary connections, this version occupies the mid-range of the family rather than either size extreme. Review the nominal sizes and gauge-port thread together before treating another GP2403 part number as interchangeable.
