The Big Horn 11421 4-Inch Plastic Dust Collection Coupling is designed to securely join two lengths of flexible dust collection hose in 4-inch systems. This precision-molded coupling fits snugly inside standard 4-inch ID hoses, allowing for easy system extensions or repairs. Made from durable ABS plastic, it resists cracking and impact damage under regular shop use. The smooth tapered ends provide a reliable friction fit and help minimize airflow loss at the joint. Use with hose clamps (not included) to ensure a tight, leak-free seal during operation. Whether you're connecting hoses to reach across the shop or bridging between tool stations, this coupling delivers dependable performance.
