6-in-1 Brush, 1/2" and 3/4" Fittings and Tubing

Blue Monster 70255 – Six-in-One Fitting and Tubing Brush for Copper Prep

The Blue Monster 70255 Six-in-One Brush is a compact, multi-purpose tool designed for cleaning both the inner diameter of copper fittings and the outer surface of tubing. This model supports 1/2" and 3/4" nominal copper sizes, making it suitable for most common residential and light commercial plumbing installations.

Each end of the tool houses a hardened steel brush for preparing the ID of fittings, while the sides contain twist-lock compartments with additional brushes for OD pipe cleaning. This design streamlines prep work for soldering and brazing tasks. The body is built from high-impact thermoplastic and features replaceable internal brushes to extend tool life and reduce replacement frequency.

Professional Use Guidance

Contractors will benefit from the integrated design that eliminates the need for separate fitting and tube brushes. The 70255 supports faster transitions between pipe sizes and reduces the likelihood of contamination between jobs. Ideal for retrofit, service, and rough-in work where time and space are limited.
