GP2403-16-16-04FB Tompkins JIC-to-JIC Gauge Port, -04 SAE O-Ring Port

If the existing plumbing uses Tompkins' GP2403 JIC-to-JIC pattern, GP2403-16-16-04FB is the version sized 16/16 with a -04 SAE O-ring port.

With GP2403, both main connections are male JIC; the separate third port is reserved for the gauge connection.

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

The matching 16/16 nominal sizing puts this model toward the larger half of the family. Because several GP2403 models share the same basic shape, use the part number and connection data below as the final fit check.
