Our plastic wedges for paint brushes, also known as paint brush ferrule inserts, plastic spacers or brush head filling strips, are designed for use inside metal ferrules during paint brush production.

The plastic wedge fills the required space inside the brush head and helps position the bristle or synthetic filament during assembly. It can also help manufacturers control the internal brush structure, maintain consistent brush thickness and improve production efficiency.

Different paint brush constructions require different wedge dimensions. We can customize the width, thickness, length, profile, color and plastic material according to your brush size, ferrule dimensions or existing samples.

These plastic inserts are suitable for flat paint brushes, wall brushes, industrial brushes and other brush products assembled with metal ferrules.

YZJD supplies a complete range of materials for paint brush manufacturing, including:

• Natural hog bristle
• PET, PBT and PA synthetic filaments

Please send us the brush size, ferrule dimensions, required wedge size, photos or physical samples. We can recommend a suitable specification or develop a customized plastic wedge for your production.
