Product Overview

4" to 2-1/2" Cone Reducer by POWERTEC.

  • INCLUDES: 4" to 2 1/2" Dust Collection Hose Reducer

  • FUNCTION: A handy double sided adapter that allows you to step down from your larger (4") dust collection hose to a smaller (2-1/2) shop vacuum hose branch line
  • PLEASE NOTE: This cone reducer is specifically designed to work exclusively with 4" and 2-1/2" hoses | It is NOT intended to fit or accommodate a 2-1/2" OD or 4" OD dust collection equipment port directly (which would require POWERTEC 70149 or 70148 Flex Cuffs)
  • PREMIUM: Made with high quality ABS plastic for long-term durability and to withstand the abrasive nature of workshop dust collection
  • DIMENSIONS: 4" nominal OD end measures 3-61/64" OD and 3-41/64" ID; 2-1/2" nominal OD end measures 2-15/32" OD and 2-9/32" ID


This limited adapter was designed to provide you with a simple solution to coupling your 4-inch ID dust hoses with 2-1/2 ID dust hoses. Specifically, it allows you to step down from a larger main line to a smaller branch line without compromising air velocity or the effectiveness of your dust collection system. It features a premium, heavy walled ABS plastic construction made for durability and to withstand the wear & tear commonly associated with woodworking dust collection. It’s extremely easy-to-use and doesn’t require messy tape or additional equipment.

"Make a clean and smart connection today with the POWERTEC Cone Reducer."


This reducer is NOT intended to be used for a direct connection to your dust collector or shop vac OD ports. It fits and accommodates hoses ONLY. If you are in need of an adapter that connects directly to your 4" dust collection equipment port, you will also require the following item:

  • POWERTEC 70149 4" Flex Cuff with Hose Clamp (sold separately)

To make a direct connection between a 4" port to another 4" port, the following adapter may be a better alternative:

  • POWERTEC 70171 Threaded Quick Coupler (sold separately)
