Professional 2-1/2 Inch Hose Screw-On Quick Coupler (70191)
Airtight Quick-Change Axial Connection for Small-Port Tools
The POWERTEC 70191 is a professional-grade 2-1/2" Hose Screw End Quick Coupler, specifically precision-engineered to eliminate the "clamp-fatigue" and air leakage common in standard tool port swaps. This specialized adapter is the definitive choice for woodworkers who need to execute 100% efficient axial transitions between a 2-1/2” I.D. left-hand flexible hose and a 2-1/4” I.D. machine port. Featuring high-impact ABS construction, the 70191 series provides the structural rigidity and airtight mechanical bond required to maintain a laminar vacuum seal across your workshop.
Constructed with a left-hand threaded architectural logic, this coupler facilitate a Laminar Airflow Path by threading directly into the hose coils, removing the need for external hose clamps. The 2-1/4" nominal O.D. end is slightly tapered to ensure a stable mechanical bond axial to tool ports, providing the mechanical security required for high-stakes fine dust collection. Whether you are connecting a router table or a benchtop sander, this coupler delivers the mechanical durability and tool-free speed required for elite shop air management.
- Elite Left-Hand Thread Logic: Threads directly into the internal helix of 2-1/2" hoses 100% efficiently, creating a zero-bypass mechanical seal.
- Surgical Tapered Design: Nominal 2-1/4" O.D. end provides a snug, axial press-on fit for rapid port-to-port tool changes.
- Industrial ABS Build: Impact-resistant and abrasion-proof construction survives the high-velocity impact of wood chips and shop debris.
- Zero-Clamp Installation: Eliminates the need for metal hose clamps axial to the hose end, providing a cleaner, lighter-weight tool connection.
- Universal Port Interface: Calibrated for a surgical fit axial to Shop Vac ports and common 2-1/4" I.D. woodworking machine dust ports.
