Schaefer Brush 93484 Spiral Tube Brush 0.75 in 6.25 in Oal

Product Description

The SCHAEFER BRUSH 93484 is a single stem spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore passages. The brush measures 0.75 inches in diameter with an overall length of 6.25 inches, including a 4-inch brush section. Fill material is silicone carbide impregnated nylon, which provides both mild abrasive action and flexible resilience in a single pass. The male connection end allows quick attachment to standard extension handles or drive tools. HVAC technicians, plumbers, and maintenance professionals use this brush for tube cleaning tasks in both service and preventive maintenance settings.

This brush is suited for cleaning copper, aluminum, and plastic tubes encountered in HVAC coil maintenance, heat exchanger service, condenser tube cleaning, and plumbing rough-in work. The spiral stem construction keeps the bristle pattern consistent through curved or restricted tube runs. At 0.75 inches in diameter, it fits tube sizes commonly found in residential and light commercial HVAC and refrigeration equipment. It ships individually and is sold in single-unit quantities.
