Small Parts, Big Difference 3M™ Vacuum Hose Adapters support optimal dust extraction by your vacuum system. Designed by 3M for 3M™ Power Tools, they are manufactured from industrial quality material and seal securely so your vacuum system can do its job. The adapters connect various sizes of vacuum hoses together and finally to a central-vacuum-ready (CV) tool. One adapter, PN 30441, connects self-generated-vacuum (SGV) tools to a Clean Sanding filter bag. Some of these adapters are "hose barb" type, meaning they push on the inside of the hose. Others have internal threads and attach on the outside of the hose. These threaded adapters feature LH or left hand threads, due to the convolution direction on the vacuum hose. This means the operator must turn the threaded hose adapter counterclockwise onto the hose to thread the two together. Improved Performance and Operator Comfort An effective vacuum system is essential for collecting dust, abraded fibers, debris and other particulate. Dust on the workpiece can mar the surface, hinder the abrasive, and fill the air you breathe. By evacuating dust effectively, you get better finishes and longer abrasive life. High quality accessories can make a big difference, and are a great example of how 3M Abrasive products enhance industrial operations, offering both ease of use and superior results.
Used to attach a 1" ID vacuum hose to another 1" ID vacuum hose. Has a 1" internal hose thread in both ends of the adapter. Allows the customer to connect 2 lengths of 1" vacuum hoses to create a longer vacuum hose. Specifications
