Schaefer Brush 93525 Tube Brush 13/16 in Stainless Steel

Product Description

The SCHAEFER BRUSH 93525 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore passages. The stainless steel bristles and stainless steel brush construction make it suitable for use in corrosive environments and applications where contamination from other metals is a concern. At 13/16 inch in diameter with a brush length of 4 inches and an overall length of 6.25 inches, this brush fits into tight passages that larger cleaning tools cannot reach. The male connection end allows it to attach to standard extension handles or drill chucks for powered or manual operation. HVAC technicians, plumbers, and maintenance professionals use this brush for tube cleaning during coil service, heat exchanger maintenance, and general pipe interior cleaning.

This tube brush is well suited for residential and light commercial applications where small-diameter tube or pipe interiors require mechanical cleaning. Typical uses include boiler tube maintenance, condenser and evaporator tube cleaning, and general-purpose pipe bore cleaning in plumbing and HVAC systems. The stainless steel construction makes it a durable choice for repeated use in both wet and dry service environments.

Installation Notes

This brush is installed by trade professionals including HVAC technicians and plumbers as part of routine tube or pipe cleaning procedures. Always isolate and de-energize or depressurize the system before inserting any cleaning tool into a tube or pipe bore. The male connection end can be attached to a hand handle or secured in a drill chuck for powered rotation. Avoid excessive force that could deform soft tubing or cause bristle splaying.
