Schaefer Brush 93725 Condenser Tube Brush 13/16 in Nylon

Product Description

The SCHAEFER BRUSH 93725 is a single stem spiral condenser tube brush designed for cleaning the interior surfaces of condenser tubes in HVAC and refrigeration systems. The brush features a nylon bristle construction wound in a spiral pattern around a single stem, allowing it to conform to tube walls and dislodge scale, debris, and fouling deposits. At 13/16 inches in diameter and 6-1/4 inches in overall length, with a 4-inch brush section, it is sized for standard condenser tube bores. The 1/4-28 male threaded connection allows attachment to standard brush extension rods. HVAC technicians and refrigeration service pros use this brush during routine condenser maintenance and coil cleaning procedures.

This brush is suited for residential and light commercial HVAC applications where condenser tube cleaning is part of a scheduled maintenance routine. It is typically used with a drill, flex shaft, or manual rod system to clean straight tube runs inside shell-and-tube condensers or similar heat exchanger configurations. The nylon bristle material is compatible with copper and aluminum tube surfaces and resists moisture and mild cleaning solutions.

Key Features

• Single stem spiral design conforms to tube ID for consistent contact along the full brush length
• Nylon bristles resist corrosion and are safe for copper and aluminum tube surfaces
• 4-inch brush length with 6-1/4-inch overall length for reach inside standard tube runs
• 1/4-28 male threaded connection compatible with standard extension rods and drill adapters

Compatibility

Designed as an OEM-style replacement and service brush for condenser tube cleaning applications in residential and commercial HVAC and refrigeration systems with tube bores sized for a 13/16-inch brush diameter.

Installation Notes

Installation and use should be performed by a qualified HVAC or refrigeration technician. Before cleaning, isolate and de-energize the equipment per lockout/tagout procedures and relieve any system pressure. Attach the brush to a compatible extension rod or low-speed drill using the 1/4-28 male thread connection. Do not force the brush into tubes that are smaller than the rated brush diameter, as this can damage bristles or tube walls.
