Compact Utility Brush
The 1/2" AB-1 Acid Brush provides a compact brush-style applicator for situations where a smaller application surface is useful. Its size allows the installer to work around smaller areas without the larger coverage provided by swabs, rollers, or oversized daubers.
This makes the brush a practical accessory to keep with other pipe preparation and solvent-cement joining tools when controlled application is needed.
Part of the Spears® Applicator Line
Spears® offers the Acid Brush as part of its broader line of solvent cement applicators and accessories. Other applicator styles include daubers, cap brushes, swabs, and rollers for different container and pipe-size requirements.
The appropriate applicator should be selected according to the product being applied, the pipe diameter, and the requirements of the joining procedure.
Useful for Smaller Application Areas
The small brush format provides greater control when working on compact surfaces and smaller areas where a larger applicator may be inconvenient.
Before use, make sure the brush is clean and suitable for the material being applied. Avoid transferring residue between products where contamination could affect the application.
Pipe Joining Accessory
When the Acid Brush is used as part of plastic pipe joining work, all pipe and fitting surfaces should still be prepared according to the requirements of the selected piping material and joining products.
Follow the applicable instructions for cutting, de-burring, cleaning, priming when required, solvent cement application, assembly, and curing before placing the piping system into service.
Installation & Selection Considerations
- Inspect the brush before use.
- Keep the applicator clean and dry.
- Confirm the brush suits the intended product.
- Avoid cross-contamination between different materials.
- Follow the application instructions for the product being used.
