The Threaded Quick Coupler by POWERTEC
This 4” dust collection coupler provides you with a portable, versatile and convenient solution to attaching your industry standard machines to dust hoses (and fittings).
With its left-hand threaded design, this quick connect attachment doesn't require hose clamps - thus eliminating the need to constantly connect and disconnect your components each time a new machine is used.
It possesses a highly durable ABS plastic construction that was designed and engineered to withstand the abrasive nature of woodshop dust collection.
It's also equipped with a taper end that allows for a snug, secure and airtight fit that won't impact the effectiveness of your dust collection system.
