Blower Hose Fitting 4in 1.25in Hose Threaded

The Blower Hose Fitting 4in 1.25in Hose Threaded (PAR41-45000) by PARAGON PRO INC is a precision-engineered adapter designed for air movement systems in tactical, military, and industrial environments. This threaded fitting serves as the critical interface between a 4-inch blower outlet and 1.25-inch hose connections, enabling operators to route compressed air or ventilation efficiently in breaching operations, equipment cooling, or NBC (nuclear, biological, chemical) decontamination scenarios. Built to military standards, this coupling ensures airtight seals and reliable performance under field conditions where equipment integrity directly impacts mission success.

The 4-inch to 1.25-inch threaded design allows for stepped-down connection without flow restriction or pressure loss, critical in applications requiring sustained airflow. The fitting's threaded construction—rather than compression-based—provides positive mechanical locking that resists vibration and maintains integrity during rapid deployment or transport. Compact dimensions (6 x 4 x 8 inches) and lightweight construction (0.34 lbs) make it easy to integrate into portable air systems, rescue equipment packages, or vehicle-mounted ventilation assemblies. The PARAGON PRO INC manufacturing standard ensures dimensional accuracy and material durability suitable for repeated field use and harsh environmental exposure.

Law enforcement SWAT teams, military combat engineers, and hazmat technicians benefit most from this adapter when assembling modular air delivery systems for tactical operations. Installation is straightforward—simply thread the 1.25-inch hose onto the fitting's male threads, ensuring hand-tight plus one-quarter turn for a secure seal without over-torquing. This fitting integrates seamlessly with standard 4-inch blower equipment and 1.25-inch reinforced hose assemblies used in breathing apparatus support, barrier inflation, or decontamination shower systems. Verify thread pitch compatibility with your existing blower manifold before purchase to ensure proper fit.
