Schaefer Brush 42630 Nylon Tube Brush 8 in Single Spiral

Product Description

The SCHAEFER BRUSH 42630 is a single-spiral nylon tube brush designed for cleaning the interior of tubes, pipes, and cylindrical passages. The brush head measures 8 inches in diameter and 4.5 inches in brush length, with a 7-inch overall length that provides good reach into standard-depth openings. Nylon fill material makes it suitable for surfaces where wire bristles could cause damage or contamination. The 0.25-inch stainless steel shank connects to standard drill chucks or flexible drive extensions, making it practical for both hand and power-assisted use. HVAC technicians, plumbers, and maintenance professionals use this brush for tube cleaning in heat exchangers, condenser coils, and piping systems.

This tube brush is suited for residential and light commercial maintenance tasks where internal bore cleaning is required. Typical applications include cleaning heat exchanger tubes, evaporator drain pans, pipe interiors, and conduit openings. The nylon fill is non-abrasive and resistant to many common cleaning chemicals, making it a practical choice when working around copper tubing, aluminum surfaces, or other soft metals. The stainless steel shank adds durability when the brush is used with a power drill or flex shaft.

Key Features

Compatibility

Designed as an OEM-style replacement or service brush for use in residential and commercial tube-cleaning applications where an 8-inch diameter single-spiral nylon brush with a 0.25-inch shank is specified.

Installation Notes

This brush is typically used by HVAC technicians and plumbers during scheduled maintenance or system servicing. Before inserting the brush into any tube or heat exchanger, shut down and de-energize the associated system per local codes and manufacturer guidance. When using with a power drill, start at low RPM to verify brush tracking before increasing speed. Do not force an oversized brush into a tube bore, as this can damage both the brush filaments and the tube wall.
