Weiler 21101 Stainless Steel Hand Tube Brush 0.25 in

Product Description

The WEILER 21101 is a single-spiral hand tube brush designed for cleaning small-diameter tubes, ports, and bores. The brush head measures 1.5 inches long with a 0.25-inch diameter, built with stainless steel fill wire at 0.005-inch wire diameter for effective scrubbing without contaminating ferrous or stainless workpieces. A galvanized steel shank with a 3/32-inch diameter connects to a loop handle for controlled manual operation. Overall length is 7 inches, giving the user adequate reach into tight passages. HVAC technicians, plumbers, and refrigeration mechanics commonly use this type of brush for tube prep, port cleaning, and debris removal in maintenance and repair workflows.

This brush is suited for light-duty hand cleaning of small tubes and fittings in residential and commercial applications. Typical uses include cleaning refrigerant line fittings, small copper or stainless tube interiors, sensor ports, and threaded passages before assembly or inspection. The stainless steel fill resists corrosion, making it appropriate for wet or chemically active environments common in plumbing and HVAC service work.

Key Features

• Stainless steel fill wire resists corrosion and prevents contamination on stainless or non-ferrous surfaces
• Single-spiral construction with one bristle spiral for consistent scrubbing across the bore
• 0.005-inch wire diameter provides firm but controlled abrasion in small passages
• Loop handle allows secure grip during manual cleaning operations
• 7-inch overall length provides reach into recessed tubes and ports
• Galvanized steel shank at 3/32-inch diameter for durability in repeated use

Compatibility

Designed for manual cleaning of tubes and bores with an inner diameter of approximately 0.25 inches, suitable for use in HVAC, plumbing, and refrigeration maintenance applications where small-diameter brush access is required.

Installation Notes

This brush is used by hand without power equipment. Isolate or depressurize any line or fitting before inserting the brush into a tube or port. Inspect the brush for bent or broken wires before each use to avoid leaving debris inside a cleaned passage. Dispose of worn brushes when fill wire shows significant deformation or shedding.
