MT-1A Threaded Mechanical Branch Tee

The Viking MT-1A Threaded Mechanical Branch Tee functions as a critical fire protection component, engineered to create secure, reliable branch connections within commercial and industrial fire sprinkler piping assemblies without requiring on-site welding. This mechanical tee installs directly onto main run lines to provide an NPT threaded outlet, streamlining the integration of branch lines, drops, or gauge connections in wet and dry pipe systems.

Designed to support full regulatory compliance, this component satisfies the rigorous installation mandates outlined in NFPA 13 for the installation of sprinkler systems, ensuring system integrity and reliable fire suppression performance. Third-party testing and certification standards are fully met to satisfy municipal code requirements and insurance stipulations across commercial facilities.

• High-Strength Ductile Iron: Built from robust ductile iron to provide exceptional resistance to mechanical stress and structural corrosion in demanding building environments.
• Weld-Free Installation: Features a bolted saddle design that clamps securely onto the main pipe, eliminating hot-work permits and speeding up job-site assembly.
• Threaded Outlet Connection: Engineered with standard NPT threaded outlets for seamless integration with steel and CPVC piping configurations.
• Certified Safety Standards: Carries both UL Listings and FM Approvals to verify compliance with strict third-party fire protection criteria.
• Corrosion-Resistant Build: Specialized exterior coatings minimize long-term maintenance requirements and extend service life across diverse facility applications.

Always verify local Authority Having Jurisdiction (AHJ) guidelines and review specific pipe schedule compatibility prior to job-site installation.
