FUNCTION: Adapter joining fittings with 4” OD port - Provides fast and seamless connection between 4 inch OD dust collector accessories such as pipes, blast gates, elbows; to connect two ID 4” hoses, see POWERTEC 70123
DESIGN: Tapered at both ends for optimal friction for a secure fit
PREMIUM QUALITY: Made with impact-resistant, heavy-duty ABS plastic, ideal for wear and tear commonly associated with the collection of 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.
