The 1JH Series Adapter is a straight hydraulic fitting designed to connect two different hydraulic connection interfaces. It combines a JIC male 74° cone end with a metric male threaded end incorporating an O-ring sealing arrangement.
The JIC end is designed to mate with a compatible JIC female 74° flare fitting. The metric end uses an O-ring sealing arrangement and is intended to mate with the corresponding compatible metric port. The O-ring size and sealing configuration must match the specified connection requirements.
This combination is useful when hydraulic equipment or piping systems require a transition between inch-based JIC connections and metric threaded ports. Its straight configuration allows direct connection between compatible hydraulic components.
The supplied dimensional table lists multiple E-end and F-end thread combinations, together with the specified F-end O-ring size and key dimensions A, B, L, and S1. These details help buyers identify the appropriate part number for their installation requirements.
NBFK can discuss OEM and customized hydraulic adapter requirements according to customer drawings, samples, or confirmed technical specifications.

The 1JH Series is intended for hydraulic connection applications where a compatible JIC 74° flare interface must be connected to a metric threaded port.
Potential application areas include:
Hydraulic machinery and equipment
Industrial hydraulic systems
Hydraulic tube and piping assemblies
Hydraulic valves, pumps, and other components with compatible connection interfaces
Equipment requiring a transition between inch-based JIC connections and metric threaded ports
Final suitability depends on the selected thread combination, port design, sealing requirements, material, and system operating conditions.
