Flow Thru Brushes

Flow Thru brushes have been called various names throughout the years. The name represents the function of the brush: It is constructed to enable liquid to flow through the synthetic or natural bristles for application. The brushes can be attached to a wide variety of media that dispense liquid, and are made out of many types of bristle material and configurations. The opposite of a Flow Thru Brush is a vacuum brush. Vacuum brushes use bristles to direct the flow of liquids or solids up through the brush rather than down the brush. If the reverse action of a brush is required, look toward a vacuum brush for your application.

Sizes and Style

Flow Thru brushes are made in a variety of sizes and styles. All the brush specifications depend on your application. Brushes are made several ways. The first is an aluminum or stainless steel hex fitting with male or female threads. The fill material is glued into place. See the picture to the Design Sheet. The second Flow Thru brush is made with the bristles attached to a ferrule through which a syringe needle with a luer connection is embedded. The third brush style has fill material stamped into any standard size ferrule. The fourth style has fill material glued into a mixing baffle tube. All these brush types are illustrated on the Design Sheet.

Fill Materials Used

Flow Thru brushes can be metal, synthetic or natural bristle brushes. The use of the brush will determine the types of fill material and handle to be used. The most common type of Flow Thru brushes are natural bristle brushes. Natural bristle works best when liquids are involved, as it does not disintegrate or leave residue and is cost effective. Synthetic materials are often used for general purpose cleaning, and some are chemical resistant. Metal materials are used for heavy duty cleaning and cleaning other metal surfaces.

General Notes

To stiffen a brush, shorten the trim length or use a larger diameter bristle. To lengthen the life of a brush, use the softest fill material appropriate for the job.
