Schaefer Brush 36048 Fiberglass Brush Handle Extension 48in

Product Description

The SCHAEFER BRUSH 36048 is a fiberglass brush handle extension designed to increase reach when using tube brushes and scrapers in HVAC, plumbing, and industrial cleaning applications. At 48 inches long and 0.44 inches in diameter, the extension connects via a 3/8 inches NPSM female fitting on one end and a 3/8 inches NPSM male fitting on the other, allowing inline chaining with compatible tools or additional extensions. Fiberglass construction keeps the extension lightweight at 0.73 pounds while providing the rigidity needed to push or pull cleaning tools through tubes, coils, and pipes without significant flex. Plumbers, HVAC technicians, and maintenance professionals use this extension to service equipment in tight or recessed locations.

The 36048 extension is suited for both residential and light commercial applications where tube brushes or scrapers need to reach into condensers, heat exchangers, drains, or pipe runs. The 3/8 inches NPSM thread pattern is a common standard fitting found on most tube brush and scraper handles, making this extension a practical addition to a technician's cleaning kit. It is sold individually and is well-suited for one-off service calls as well as regular maintenance routines.

Compatibility

Designed for use with tube brushes and scrapers that accept a 3/8 inches NPSM threaded connection. Multiple extensions may be chained together using the matching male and female NPSM fittings.

Installation Notes

Thread the 3/8 inches NPSM female end onto a compatible brush or scraper handle by hand until snug before applying rotational or linear force. When chaining multiple extensions, ensure each connection is fully threaded to prevent separation during use. No special tools are required for assembly, but verify that the connected brush or scraper is rated for the combined extension length to avoid binding or excessive flex. Always shut off and lock out any powered cleaning equipment before attaching or detaching extension components.
