TapeTech Corner Flushers make quick work of wiping or finishing inside corners. Direct flushers are used to apply joint compound to internal corners. Indirect flushers simply smooth compound that has been applied by another tool. TapeTech flushers work as both a direct and indirect flusher. That means you don’t have to decide which model to get, only which sizes fit your needs. The Corner Flushers fit all TapeTech corner tools (Compound Tubes, XHTT and FHTT handles, CA07TT and CA08TT Corner Applicators and 14TT MudRunner®).
