Gauge ports provide a convenient connection point for installing pressure gauges or accessing a hydraulic system for pressure monitoring and testing. This collection includes multiple gauge-port configurations designed to integrate a pressure connection into common hydraulic fitting arrangements.
Available styles include JIC-to-JIC, JIC-to-O-ring, and JIC swivel gauge ports in a range of nominal thread sizes. Depending on the series, the gauge connection is available with either a -04 SAE O-ring port or a -04 female pipe port.
When selecting a gauge port, confirm the fitting configuration first, then verify the nominal thread sizes on both ends and the type of gauge connection required. Fixed JIC configurations and swivel designs serve different installation needs, while JIC-to-O-ring versions provide an option for systems using SAE O-ring connections.
Gauge ports are part of the pressure-monitoring connection between the hydraulic system and the measuring equipment. If you also need the instrument itself, browse our complete pressure gauges collection.
Use the products below to compare gauge ports by fitting family, port type, nominal thread size, and connection configuration.
