Figure 211 | 2,000 PSI Insulating Hammer Union
C&C Industries
The C&C Figure 211 Insulating Hammer Union is designed to provide both pressure sealing and electrical isolation in pipeline systems where corrosion control is critical. By eliminating metal-to-metal contact between components, it prevents electrical current flow that can accelerate corrosion in protected systems.
Featuring a BUNA-N O-ring on the male sub and a neoprene insulating seal on the female sub, the union delivers reliable sealing while maintaining electrical separation. This makes it ideal for use in systems utilizing cathodic protection.
Built for 2,000 PSI service, the Figure 211 is a key component in maintaining long-term pipeline integrity in corrosive environments.
Typical Applications:
Cathodic protection systems, corrosion control installations, pipeline isolation points, oil & gas production systems, and process piping

PERFORMANCE ADVANTAGES
Why the FIG 211 Performs Where It Counts
PREVENTS ELECTRICAL CURRENT
TRANSFER & CORROSION
By isolating metal components, the union blocks stray current flow that leads to galvanic and electrochemical corrosion. This is essential in systems using cathodic protection.
MAINTAINS PRESSURE SEALING WHILE PROVIDING ISOLATION
Unlike basic insulating solutions, the Figure 211 integrates both sealing and isolation into one design, ensuring neither function is compromised.
EXTENDS PIPELINE LIFE
IN CORROSIVE ENVIRONMENTS
Preventing electrical corrosion significantly reduces material degradation, helping extend the lifespan of piping systems and lowering replacement costs.
REDUCES RISK OF HIDDEN FAILURE POINTS
Electrical corrosion often develops internally and goes unnoticed until failure occurs. This union eliminates that risk by stopping the root cause.
