Color: Black Size: 0.9 inches Dust Collector Fittings: 1-2/3 inch, 1-1/3 inch, 1.1 inch, 0.9 inch, 1-3/4 inch, compatible with 1- 1/4 inch diameter vacuum cleaner hose, suitable for handheld power tools with interable connectors that can be immediately disconnected with just a light press. Vacuum Attachment Adapter: Vacuum cleaner hose of elastic weather-resistant rubber and polyester fiber. The inner wall of the hose is smooth to reduce air flow resistance, and the outer spiral steel wire enhances the tensile strength, which can withstand the high-pressure suction force and repeated bending during collection. The vacuum accessory adapter is made of ABS engineering plastic and undergoes high-temperature curing treatment. Universal Vacuum Hose Adapter: The suction port diameters of different equipment may vary (for example, the suction port of some sanding machines is 1 inch, while that of electric saws is 1.5 inches). At this point, the 1-1/4 inch main hose can precisely connect to the suction ports of each device through the corresponding specification converters among the 7 vacuum adapters, forming a closed-loop collection channel. This channel directly guides the into the collection bucket, preventing wood chips from flying and polluting the workshop air, while also reducing the wear inside the equipment caused by accumulation. Hose Adapter: It can be easily connected to various devices and additional tools. Even when replacing the old hoses and connectors, the entire process can be completed in just a few seconds, saving both time and effort and making installation no longer a burden. Sander Vacuum Adapter: Strictly inspected before shipment to ensure reliability.
