Schaefer Brush 93728 Condenser Tube Brush 7/8 in Nylon

Product Description

The SCHAEFER BRUSH 93728 is a single stem spiral condenser tube brush designed for cleaning the interior walls of condenser tubes in HVAC and refrigeration systems. The brush measures 7/8 inch in diameter with an overall length of 6.25 inches and a brush length of 4 inches. Nylon bristles provide effective mechanical scrubbing without damaging tube surfaces. The male connection end allows attachment to standard extension rods for reaching into tube bundles. This brush is installed and used by HVAC technicians and refrigeration mechanics performing routine condenser maintenance and cleaning.

This brush is suited for residential and light commercial HVAC and refrigeration applications where condenser tube fouling reduces heat transfer efficiency. It is used during scheduled maintenance shutdowns to remove scale, biofilm, and debris from the inner diameter of condenser tubes. The spiral bristle configuration provides full contact around the tube wall as the brush is pushed or rotated through the tube. Compatible with standard tube cleaning rod systems that accept male-connection brush attachments.

Key Features

• 7/8 inch brush diameter sized for matching condenser tube inner diameters
• Spiral bristle pattern ensures full circumferential contact inside the tube
• Nylon bristles resist corrosion and will not scratch or score metal tube walls
• 4-inch brush length covers adequate surface area per stroke
• Male connection end is compatible with standard extension rod systems
• Lightweight at 0.1 pounds for easy single-handed operation

Compatibility

Designed for use with standard tube cleaning rod systems that accept a male-connection condenser tube brush. Suitable for condenser tubes with an inner diameter matched to the 7/8 inch brush size in HVAC and refrigeration equipment.

Installation Notes

Shut down and lock out the refrigeration or HVAC system before accessing the condenser tube bundle. Attach the brush to an appropriate extension rod before inserting into the tube. Push and rotate the brush through the tube using smooth, consistent strokes to avoid bending the stem. Collect and dispose of dislodged debris in accordance with local environmental and facility procedures.
