It is of paramount importance to keep the threads of the CPT tubes as clean as possible. Only clean threads lock correctly assuring in that way the strongest connection possible between 2 tubes.
In order to clean the threads of CPT tubes thoroughly, Gouda-geo proposes this tapered steel brush to clean the interior threads and handheld steel brush for the exterior threads. The tapered steel brush can be used in conjunction with a cordless drill. Removes dirt and rust effectively.
Two sizes are available for both the 36 and 44 mm CPT tubes.
