This setup is to be used with any of SurfPrep’s vacuum compatible sanders. SurfPrep Sanders with vacuum conversion have a 1" female piece at the back of the tool that attaches to a 1" ribbed vacuum hose. This specific setup comes with the following parts:
3 feet of flexible hose (SPSCHW-1)
1 swivel coupler for a 1" hose to 1" hose (SPA1-1)
7' Blue vacuum hose (7-SPVH)
This vacuum hose setup will most likely need an additional adapter if you want to seamlessly hook up to a different brand of vacuum.
