Schaefer Brush 93522 Tube Brush 3/4 in Stainless Steel

Product Description

The SCHAEFER BRUSH 93522 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and bore holes where a durable, corrosion-resistant brush is required. The brush measures 0.75 inches in diameter with an overall length of 6.25 inches, including a 4-inch brush or scraper length. Stainless steel bristles and a stainless steel construction make this brush well suited for applications involving moisture, mild chemicals, or residue buildup that would quickly degrade lesser materials. It connects via a male fitting for use with standard tube brush handles or extensions. Plumbers, HVAC technicians, and industrial maintenance personnel are the primary installers and users.

This tube brush sees typical use in residential and commercial plumbing and HVAC service work, where cleaning tube interiors, heat exchanger passages, and bore holes is part of routine maintenance or repair. The 0.75-inch diameter targets smaller tube and pipe bores, and the single spiral configuration provides consistent contact with the tube wall. It is equally at home in light industrial settings for cleaning ports, manifolds, or any bore requiring mechanical scrubbing action.

Key Features

• Double stem construction provides added rigidity and support during scrubbing
• Single spiral pattern ensures consistent bristle contact along the full brush length
• Stainless steel bristles resist corrosion and hold up in wet or mildly chemical environments
• Male connection type is compatible with standard tube brush handles and extensions
• Compact 6.25-inch overall length allows use in confined access areas

Compatibility

Designed as an OEM-style replacement and general-purpose tube brush for residential and commercial plumbing, HVAC, and industrial maintenance applications requiring a 0.75-inch diameter bore brush with a male connection.

Installation Notes

This brush is installed by hand or attached to a compatible handle or drill extension for power scrubbing. Before cleaning any tube or passage on an active system, shut off fluid flow and relieve system pressure per local plumbing or mechanical codes. Inspect the brush for bent stems or damaged bristles before each use, as deformed brushes can shed wire inside a system. Wear appropriate eye protection when using wire brushes in any orientation.
