Schaefer Brush 30548 Brush Handle Extension 36 in

Product Description

The SCHAEFER BRUSH 30548 is a galvanized steel brush handle extension designed to increase reach when cleaning tubes, pipes, and tight interior passages. At 36 inches in overall length with a 0.32-inch diameter shaft, it threads onto compatible brushes and scrapers via a 1/4-inch NPSM female connection. The galvanized steel construction resists corrosion and provides the rigidity needed to push or pull tube brushes through heat exchangers, condenser tubes, boiler flues, and similar confined passages. Technicians working in HVAC, plumbing, and industrial maintenance will find this extension useful wherever extra reach is required without sacrificing control.

This extension is suited for residential and light commercial service applications where standard-length brush handles fall short. Typical scenarios include cleaning finned tube coils, boiler fire tubes, and drain lines. It is intended for use with tube brushes and scrapers that accept a 1/4-inch NPSM female threaded connection. The single-piece galvanized shaft keeps the assembly lightweight at 1.04 pounds while maintaining enough stiffness to transmit scrubbing force along the full 36-inch length.

Key Features

• 36-inch overall length for extended reach into tubes and passages
• 0.32-inch shaft diameter for compatibility with standard tube brush sets
• 1/4-inch NPSM female threaded connection for secure brush attachment
• Galvanized steel construction for corrosion resistance in wet service environments
• Lightweight at 1.04 pounds for reduced fatigue during extended cleaning tasks

Compatibility

Designed for use with tube brushes and scrapers that accept a 1/4-inch NPSM female threaded handle connection. Verify thread type and shaft diameter against your existing brush set before ordering.

Installation Notes

Thread the 1/4-inch NPSM female end onto the male shank of a compatible tube brush or scraper before inserting into the passage being cleaned. Ensure the connection is hand-tight to prevent separation during use. No power tools are required for assembly. When cleaning heat exchangers or boiler tubes, follow applicable equipment lockout/tagout procedures before accessing internal passages.
