Weiler 41018W Marking Brush 1/4 in Flat Ox Hair

Product Description

The WEILER 41018W is a flat marking brush built for precise line work, part identification, and layout marking in trade and industrial settings. It features natural ox hair bristles measuring 0.875 inches in length, mounted on a wood handle. The 1/4 inch brush size and flat shape make it well suited for applying layout fluid, cement, flux, or paint to small, defined areas. At 0.01 pounds, the brush is lightweight and easy to handle during detailed work. Installers, fabricators, and tradespeople who need clean, controlled marking in confined spaces will find this brush a reliable hand tool on the job.

This marking brush is used across a range of trade applications including HVAC ductwork layout, pipe fitting, electrical conduit marking, and general fabrication. It performs well when applying marking fluids, soldering flux, pipe cement, or layout dye to metal, PVC, and wood surfaces. The flat bristle shape allows edge-to-edge contact on narrow work surfaces, making it practical for both bench work and field installations where accuracy in marking saves time on cuts and fittings.

Installation Notes

This brush is a hand tool requiring no power or mechanical installation. Rinse or clean the bristles promptly after use with the appropriate solvent for the fluid applied to extend bristle life. Avoid soaking the wood handle in solvent or water, as prolonged exposure can loosen the ferrule and degrade the handle. Store flat or bristle-end up to maintain bristle shape between uses.
