O-Ring Union | Injection System Union Connection
Forum Energy Technologies (FET)
The FET O-Ring Union is designed to simplify the construction, maintenance, and modification of injection assemblies by allowing quick disconnection of components without dismantling the entire system. It provides a secure, leak-resistant connection while enabling rapid servicing and component replacement.
Built from 316 or 316L stainless steel with a nitrile O-ring seal, the union delivers reliable performance in high-pressure injection environments. Its design supports both threaded and socket weld connections for flexibility in system integration.
With working pressures up to 3,705 PSI, the O-Ring Union is a critical component in modular injection system design.
Typical Applications:
Injection assemblies, wellhead systems, flow control setups, maintenance isolation points

PERFORMANCE ADVANTAGES
Why the FET O-Ring Union Performs Where It Counts
FAST MAINTENANCE & REPLACEMENT
Allows operators to isolate and remove individual components without breaking down the entire system. Reduces downtime and simplifies servicing.
LEAK-RESISTANT HIGH-PRESSURE CONNECTION
O-ring sealing design provides reliable sealing under high-pressure conditions, reducing the risk of leaks compared to threaded-only connections.
MODULAR SYSTEM FLEXIBILITY
Supports flexible system design by enabling easy reconfiguration of injection assemblies. Ideal for evolving field conditions.
DURABLE PERFORMANCE IN CORROSIVE SERVICE
Stainless steel construction resists corrosion and wear, ensuring long-term reliability in injection environments.
