Product Overview

Introducing the 4" to 2-1/2" Tapered Reducer Adapter by POWERTEC

This adapter is uniquely designed to attach a 2-1/2" ID dust collection hose directly to a 4" OD machine port.  The adapter uses a friction fit to fit inside the 4"OD port without the need of cuffs or couplers, making a quick disconnect that can be used for multiple machine setups.

  • Includes: (1) Tapered Reducer Adapter (Black)
  • Function: Serves as a 4" to 2-1/2 inch dust collection hose reducer and is designed to fit inside most 4-inch OD ports with a friction fit
  • 4-Inch Dust Collection Fitting End: Designed with a tapered 4" end (tapers from 3.51" to 3.73") that connects directly into a 4-inch nominal OD port
  • 2-1/2" Inch Dust Collection Fitting End: Also possesses a tapered 2-1/2" OD end (tapers from 2.45" to 2.49") that fits inside most 2-1/2" ID dust collector hoses
  • Premium Build: Constructed with high quality ABS plastic for long-term durability and made to withstand the abrasive nature of workshop dust collection

Featuring a tapered design, this unique adapter/reducer sits firmly inside your fittings and possesses a small and large end - both with tapered profiles intended to give you a no-nonsense fit for your dust collection hoses and components.

  • 2-1/2 Inch Nominal OD End (tapers from 2.45" - 2.49") to deliver a precise connection for a 2-1/2" ID dust hose.
  • 4 Inch End uniquely designed to fit inside a nominal 4"OD port or fitting (tapers from 3.51" - 3.73") to produce an accurate connection for a 4" OD dust collection port without the need of cuffs or couplers.
