About Washers

Made of durable material, these washers resist wear from rubbing and scraping surfaces. They create a light duty seal around fasteners to prevent fluids from leaking and damp vibration.

ePTFE plastic washers have excellent weather resistance.

Choose-a-Color Frame Floor Squeegees with Scraper

A scraper removes tough debris. Assign frame colors to different tasks or areas to avoid cross contamination. Neoprene blades resist oil, grease, and chemicals. Blades are two ply, making them good for uneven surfaces and for moving more liquid so floors dry quickly. Fiberglass handle is hygienic.

Antistatic Swabs

These swabs dissipate static electricity and are often used for cleaning electronic components. They are tear resistant.

Polyurethane foam swabs are abrasive, so they’re good for cleaning. You can also use them to apply adhesives and solvents.

Polyurethane foam over cotton swabs have an inner cotton core for padding and extra absorbency. In addition to cleaning, they’re good for applying adhesives and solvents.

Styles C and D have a tip that is small and pointed for precision cleaning.
