FIG 1502 is a high-pressure union connection commonly used in well service and stimulation applications. Selection should account for working pressure, service temperature, fluid compatibility, end connections, inspection status, and the complete pressure envelope of the assembled system.
What is a FIG 1502 connection?
FIG 1502 refers to a union configuration widely used to connect high-pressure flowline equipment. Its compact profile and field-friendly make-up support fast rig-up where space and time matter.
The figure number identifies the union design, not a complete guarantee that every component is suitable for every job. The manufacturer, material class, seal configuration, temperature, service environment, and current inspection condition still matter.
Understanding the pressure rating
Many FIG 1502 components are associated with a 10,000 PSI cold working pressure, but crews should verify the stamped rating and documentation for each individual component. The lowest-rated component determines the safe working limit of the assembled line.
Pressure ratings can be affected by temperature and service conditions. Never infer a component rating from color, appearance, or connection style alone.
A practical selection checklist
- Confirm maximum anticipated working and test pressure.
- Match nominal size, union figure, and male/female orientation.
- Confirm fluid, gas, sour-service, and temperature compatibility.
- Review inspection status, traceability, and visible condition.
- Check the assembled system for mixed ratings or incompatible components.
Where Sterling can help
Sterling organizes available equipment by drawing number, connection, configuration, and quantity. That gives buyers and field teams a clear starting point for confirming fit before a quote or dispatch.
Frequently asked questions
Is every FIG 1502 component rated to 10,000 PSI?+
No. Always verify the rating marked on the specific component and its supporting documentation. System working pressure is limited by its lowest-rated component.
Can different manufacturers’ unions be mixed?+
Compatibility should never be assumed. Confirm dimensional, material, seal, and service compatibility with qualified technical personnel before assembly.
What details should I include in an RFQ?+
Include nominal size, figure number, working pressure, end orientation, length or style, service conditions, required quantity, and any inspection or documentation requirements.
