Armstrong International B2311C-2 Connector Block

The Armstrong International B2311C-2 Connector Block is a critical component for steam system modernization, specifically engineered for use with 360° universal swivel steam traps. Constructed from 304 stainless steel, this 3/4" NPT connector block provides a permanent, corrosion-resistant mounting station that remains in-line during trap maintenance. Designed for high-pressure saturated steam applications, the B2311C-2 standardizes trap station piping, allowing technicians to replace worn steam trap modules in minutes without breaking pipe connections. This in-line steam trap connector utilizes a robust two-bolt mounting pattern, ensuring a reliable mechanical seal and minimizing potential leak paths in a condensate return system. By decoupling the trap body from the piping, the Armstrong B2311C-2 significantly reduces labor costs and downtime during routine system inspections. Its 316 stainless steel internal components and heavy-duty casting make it suitable for industrial steam header environments where long-term durability and chemical resistance are mandatory requirements for steam system efficiency and fluid handling performance.

Technical Benefits for Contractors

• 304 Stainless Steel Construction: Provides superior resistance to carbonic acid and minimizes galvanic corrosion within the piping system.
• Permanent In-Line Installation: The 3/4" NPT threaded connections stay fixed, eliminating the need to re-pipe during trap failure.
• Universal Compatibility: Designed for seamless integration with Armstrong 360° swivel series steam traps and competitive universal modules.
• Simplified Maintenance: Features a heavy-duty two-bolt flange design that facilitates rapid steam trap replacement without specialized tools.

Common Installation Questions

Is the Armstrong B2311C-2 compatible with other brands?
Yes, this stainless steel connector block uses the industry-standard two-bolt swivel mount, making it compatible with most manufacturers' universal trap modules.

What is the maximum operating pressure for this connector?
The B2311C-2 is typically rated for saturated steam applications up to 650 psig (45 bar), depending on the specific trap module it is paired with.

Does this block include the mounting bolts?
Standard Armstrong connector blocks are often sold as standalone units; however, the mounting hardware is typically provided with the replacement steam trap module to ensure proper torque specs.
