Schaefer Brush 30328 Brush Handle Extension 36in Galvanized

Product Description

The SCHAEFER BRUSH 30328 is a galvanized steel brush handle extension designed to increase the reach of tube brushes and scrapers used in HVAC, plumbing, and industrial pipe cleaning applications. Measuring 36 inches in overall length with a 0.32-inch diameter shaft, it connects via a 1/4-inch NPSM female thread. The galvanized steel construction resists corrosion in wet or high-humidity environments, making it a practical choice for drain line, condenser coil, and tube cleaning work. HVAC technicians and plumbers install this extension when standard brush handles cannot reach deep into pipes, coils, or other confined passages.

This handle extension is suited for residential and light commercial service work wherever tube brushes or scrapers need additional reach. Common applications include cleaning evaporator drain pans, condenser tubes, boiler tubes, and plumbing pipe interiors. The 1/4-inch NPSM female connection threads directly onto compatible brush and scraper handles. The 36-inch length covers most standard reach requirements without the need for multiple extensions in typical service scenarios.

Installation Notes

Thread the 1/4-inch NPSM female end onto the male-threaded handle of a compatible tube brush or scraper by hand until snug. No special tools are required for connection. Ensure the system being cleaned is depressurized and drained before inserting the brush assembly into any pipe or tube. Inspect threads for damage before each use to prevent cross-threading or connection failure during operation.
