Schaefer Brush 30666 Fiberglass Brush Handle Extension

Product Description

The SCHAEFER BRUSH 30666 is a fiberglass brush handle extension designed to increase reach when using tube brushes and scrapers. At 72 inches in overall length and 0.35 inches in diameter, this extension rod is built for accessing deep or difficult passages in HVAC, plumbing, and industrial maintenance applications. The female end is threaded 1/4 inches NPSM to accept compatible brush and scraper handles, while the male end allows daisy-chaining with additional extensions. Fiberglass construction keeps the extension lightweight and resistant to corrosion, making it a durable choice for repeated service use. Weighing 0.75 pounds, it is easy to handle during overhead or confined-space work.

This extension is suited for service technicians working on heat exchangers, boiler tubes, condenser coils, and drain lines where standard-length handles fall short. It works with tube brushes and scrapers that accept a 1/4 inches NPSM male threaded connection. Typical users include HVAC technicians, plumbers, and industrial maintenance crews performing tube cleaning or scale removal in residential, commercial, and light industrial settings.

Installation Notes

No special tools are required for assembly. Ensure any system being serviced is depressurized and de-energized before inserting the extension into tubes or passages.
