Electrical-Insulating Plastic Washers

Metric Electrical-Insulating Plastic Washers

Plastic Washers for Rigid Insulation

Plastic washers resist moisture, chemicals, and friction and are good electrical insulators.

Color-Coded Horseshoe Shims

These shims are color-coded by thickness for easy identification. The horseshoe design fits around screws.

Tapered Shims

Ridges keep these shims from sliding apart when stacked.

Polypropylene Unthreaded Spacers

Polypropylene spacers have a hard surface and resist many chemicals and solvents.

Unthreaded Spacer Stock

Cut stock to the length you need.

Control of Liquids, Gases, and Solids

Large-Particle Suction Strainers

Strainers have a heavy duty construction to withstand a high suction force and wide openings to trap large debris.

Polypropylene Y-Strainers

High-Capacity Plastic Y-Strainers

A wide two-piece body holds more debris than other plastic Y-strainers. The body comes apart for easy cleaning without disconnecting your line.

T-Strainers

Install these high-capacity T-strainers prior to valves, pumps, and nozzles to protect sensitive equipment.

Chemical-Resistant T-Strainers

Made of chemical-resistant plastic, these strainers can withstand exposure to salt solutions and solvents that can corrode metals.

High-Capacity T-Strainers

Well suited for high-flow applications, these strainers have an extra-long housing and screen for greater debris-holding capacity than our other T-strainers.

Extended-Life Submersible/Open-Air Pumps for Water

These pumps can be submerged or connected remotely to a pipe in your line. Magnets turn the impeller so there's no shaft seal to wear out. Use to circulate water in small tanks, cooling baths, fountains, and other low-flow applications.

Extended-Life Submersible Pumps for Water

Magnets turn the impeller so there's no shaft seal to wear out. Submerge these pumps to circulate water in small tanks, cooling baths, fountains, and other low-flow applications.

Snap-In Fabric Grommets

No setting tools needed—snap the two parts together in a hole you've already cut to strengthen the hole and eliminate fraying. Use these grommets in tarps, covers, curtains, and other material.

Push Brooms

Push Brooms for Smooth Surfaces

These brooms have soft, flexible bristles that sweep away fine to medium dust and dirt on nonporous surfaces such as tile, wood, and smooth concrete.

Lightweight Push Brooms for Smooth Surfaces

A durable steel strip locks in bristles without the added weight of a wood or plastic block. Bristles are chemical-resistant plastic.

Lightweight Push Brooms for Semi-Smooth Surfaces

A durable steel strip locks in bristles without the added weight of a wood or plastic block. Bristles are chemical-resistant plastic.

Choose-a-Color Push Brooms
for Semi-Smooth Surfaces

Assign specific bristle colors to particular tasks or areas. Chemical-resistant bristles are fused to a chemical-resistant block so contaminants have fewer places to hide.

Low-Clearance Push Brooms for Semi-Smooth Surfaces

An adjustable-angle handle allows you to sweep in tight spaces. Bristles are chemical-resistant plastic.

Push Brooms for Semi-Smooth Surfaces

Commonly used on sidewalks and driveways, these brooms have stiff bristles that can move heavier debris than brooms for smooth surfaces.

Choose-a-Color Push Brooms for Rough Surfaces

Assign specific bristle colors to particular tasks or areas. Chemical-resistant bristles are fused to a chemical-resistant block so contaminants have fewer places to hide.

Chemical-Resistant Push Brooms for Rough Surfaces

The plastic bristles on these brooms resist chemicals, solvents, and acids.

Lightweight Push Brooms for Rough Surfaces

A durable steel strip locks in bristles without the added weight of a wood or plastic block. Bristles are chemical-resistant plastic.

Low-Clearance Push Brooms for Rough Surfaces

An adjustable-angle handle allows you to sweep in tight spaces. Bristles are chemical-resistant plastic.

Brooms

Heavy Duty Brooms

Strong and secure—bristles are housed in a steel cap and held with a wire band, good for sweeping heavy debris.

Choose-a-Color Angle Brooms
for Semi-Smooth Surfaces

Assign colors to tasks or areas.

Choose-a-Color Angle Brooms for Smooth Surfaces

Assign colors to tasks or areas.

Extra-Wide Angle Brooms for Smooth Surfaces

They're 50% wider than our other angle brooms, allowing you to clean a larger area.

Fork-Mount Brooms

Turn your forklift into a sweeper. Efficiently clean large areas such as parking lots and factory floors.

Brushes for Swing-Style Floor Buffer/Scrubbers

Brushes for Compact Swing-Style
Floor Buffer/Scrubbers

Hand Brooms and Brushes

Dust Brushes

Chemical-Resistant Dust Brushes

Bristles are made from chemical-resistant materials.

Choose-a-Color Dust Brushes

Reduce the possibility of cross contamination by designating colors to certain areas of your facility.

Chemical-Resistant Chip Brushes

Chemical-resistant plastic bristles are flexible and narrow, making them a good choice for a variety of spills in small spaces.

Scrub Brushes, Swabs, and Dusters

Wet Swabs

The tips of these swabs are soaked with isopropyl alcohol.

Multi-Angle Scrub Brushes with Extended-Reach Handle

Bristles remain on the floor whether you're standing or bending, helping you clean hard-to-reach areas like corners, baseboards, up walls, or under equipment.

Soft-Bristled Scrub Brushes
with Extended-Reach Handle

Often used to clean windows and vehicles, these soft-bristled brushes won’t scratch. Their bristle block has a wrap-around bumper to protect surfaces.
