Product Overview

Introducing the 4-Inch Dust Collection Fittings Connector by POWERTEC.

  • INCLUDES: 4" Quick Connect Dust Port Coupler
  • FUNCTION: Adapter joins fittings with 4" OD ports - Providing a fast and seamless connection between 4 inch OD dust collection accessories such as pipes, blast gates, elbows; To join two pieces of 4" ID hose, please see POWERTEC 70123 splice 
  • PRACTICAL DESIGN: Tapered on both ends with optimal friction for a snug and secure fit
  • PREMIUM BUILD: Made with impact resistant, heavy duty ABS plastic material ideal for the wear & tear commonly associated with collecting workshop saw dust, wood chips and abrasives
  • DIMENSIONS: One end measures 4-1/4" O.D. | 3-31/32" I.D. and the other end measures 4-1/4" O.D. | 3-15/16" I.D. The smaller end helps improve fit due to tolerance mismatch. If your fitting is too tight or loose simply reverse the coupling.  

This dust collection attachment provides you with a compact, versatile and convenient solution to connecting your 4" OD pipes, Y branches, T branches, elbows, blast gates and more. It comes equipped with dual tapered ends with 4" nominal I.D. openings that work exclusively with (and accept) 4" O.D. ports – and they don’t require tape or hose clamps. Possessing a highly durable ABS plastic construction, it delivers optimal friction for a snug and secure fit without impacting the effectiveness of your dust collection fittings. This quick connect disconnect tool is ideal for improved workflow or anyone multitasking between dust collector machines.


  • Tapered End: 4-Inch nominal inner diameter end presses onto 4-Inch diameter tapered dust collection port
  • Please Note: This item is intended for 4" OD dust collection fittings. It is not meant to connect a pair of 4" ID hoses together (SEE POWERTEC 70123)


4-Inch nominal ends measure tapered 4-1/4-Inch O.D. | 3-31/32-Inch I.D. and 4-1/4-Inch O.D. | 3-15/16-Inch I.D.
