Schaefer Brush 93707 Condenser Tube Brush 7/16 in Nylon

Product Description

The SCHAEFER BRUSH 93707 is a single stem spiral condenser tube brush designed for cleaning the interior walls of condenser tubes and heat exchanger tubes in HVAC and refrigeration systems. Built with nylon bristles, this brush provides effective mechanical scrubbing without damaging softer tube materials. The brush measures 7/16 inch in diameter with an overall length of 6.25 inches and a brush section length of 4 inches. The male connection end allows it to attach to standard cleaning rods, making it a practical hand tool for HVAC technicians and refrigeration service professionals performing routine condenser maintenance.

This condenser tube brush is suited for residential and light commercial HVAC applications where condenser tube fouling reduces heat transfer efficiency. It is commonly used during seasonal maintenance and coil cleaning service calls. The nylon bristle construction makes it appropriate for use in aluminum and copper tube applications where wire bristles would risk scoring or gouging tube walls. Technicians use this brush by hand or with extension rods to pass through individual condenser tubes and remove scale, biofilm, and debris buildup.

Key Features

• 7/16 inch brush diameter sized for standard condenser tube interiors
• 4 inch brush section length for effective tube wall contact
• 6.25 inch overall length provides reach without an extension rod for shorter tubes
• Nylon bristles safe for use on aluminum and copper tube materials
• Male connection end compatible with standard cleaning rod systems
• Single stem spiral construction maintains consistent bristle contact along tube wall

Compatibility

Designed as an OEM-style replacement brush for use in residential and light commercial condenser tube cleaning applications where a 7/16 inch diameter tube brush is required.

Installation Notes

Installation of this brush is performed by licensed HVAC or refrigeration technicians as part of condenser tube cleaning service. Always shut down and lock out the system before accessing condenser tube sections. Use appropriate personal protective equipment when working around coil surfaces and residual refrigerant or chemical cleaners. The male connection end should be threaded securely onto a compatible cleaning rod before use to prevent separation inside the tube.
