Use these dust caps and plugs to keep contaminants out of your hose line.

Protect your mated connections from moisture and light splashing.

Caps are watertight to protect hazardous location safe-break plugs when not in use.

A rubber seal and stainless steel hardware give these connectors excellent chemical resistance. They're rated NEMA 12, 4X, and IP65 for protection against corrosion, oil, and washdown environments.

Protect RJ45 connectors on Ethernet cables from strain when cables are pulled and bumped.

Change a turn-lock to a straight-blade connection, or a straight-blade to a turn-lock connection.

Place a plug into an opening and tighten the wing nut—the sides expand to create a seal in holes of varying diameters.

The hollow construction allows these plugs to compress for a snug fit in threaded and unthreaded holes of varying diameters. Good for electroplating, paint baking, and powder-coating applications, they withstand temperatures up to 450° F.

These plugs have excellent chemical resistance for masking parts during chemical finishing applications such as plating and anodizing. Their tapered design fits a range of hole diameters.

With a compressible flanged top, these plugs are designed to seal the ends of copper tubing often used in water supply lines, refrigerant lines, and HVAC compressors. All are sized to fit standard copper tube dimensions.

Good for electroplating, paint baking, and powder-coating applications, these plugs withstand temperatures up to 600° F. To form a tight seal, use the smaller end of the plug to pull the larger end into a through hole.

Designed with a flange, these plugs protect countersunk holes during anodizing, electroplating, paint baking, and powder-coating applications. All withstand temperatures up to 600° F. Use the smaller end of the plug to pull the larger end into a through hole to form a tight seal.

A time-saving alternative to threaded plugs, these plugs press in place and have an ergonomic pull tab for quick and easy removal. Use them to temporarily protect holes in objects from contaminants during storage, painting, and light fabrication.

The wings on these plugs expand against the sides of a hole to form a liquid-tight seal. Pierce the plugs with round wire, cable, or tubing and they function as a grommet to create insulated holes.

Good for electroplating, paint baking, and powder-coating applications, these caps withstand temperatures up to 440° F or 570° F.

Made of silicone, these caps withstand temperatures of 450° F for electroplating, paint-baking, and powder-coating applications. All of these flexible caps are tapered to fit a variety of unthreaded and threaded objects.

Tug on the pull tabs to stretch these caps onto the tips of bottles, beakers, flasks, and cylinders, creating an airtight seal.

Tighten the nut on these plugs to expand the seal.

Twist the easy-grip t-handle on these plugs to expand the seal.

Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve pressure while testing.

Penetrate tight pipe junctures with the most flexible expansion plugs we offer.

Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve back pressure while testing.

Insert these plugs deep within your pipe to seal it off from the inside.

The face of these grips is flush with the cable-entry point for a seamless appearance.

The face of these grips is flush with the cable-entry point for a seamless appearance. They have a thin, flexible seal that covers the holes until you push a cord through.

FDA compliant for direct food contact, these cord grips have a multi-piece design to wrap around cables in sanitary environments without removing connectors or rewiring.

Create a tight seal around wire, cable, and cords with these grommets to keep out dust, debris, and moisture.

Cut the center of these grommets with a utility knife to create custom IDs. The two‐piece design makes it easy to install and seal these grommets around wire, cable, and cords that are already in place. Use them to keep out dust, debris, and moisture.

Create a sanitary seal on through-wall piping, tubing, and cables in food-, cosmetic-, and pharmaceutical-processing areas.

Cut the thin layer of rubber in the center of these grommets to create custom IDs to securely hold and protect wire, cable, and cords. Push these grommets into place. They turn rough-edged and uneven holes into smooth, insulated holes. Commonly used in metal panels, they also damp vibration. Also known as webbed grommets.

Keep grommets of various sizes on hand to solve whatever problems arise.

The stem on these bumpers compresses to fit into tight holes. Push the stem into a hole for quick installation. These bumpers are commonly used as feet on instruments and bench-top equipment to keep them from sliding. They're also good as spacers between sheets of material. Also known as stem and grommet bumpers.

Keep bumpers of various shapes, materials, and mounting styles on hand to solve whatever problems arise.

With a split design, you can easily place these bumpers on tubing, rods, machinery legs, control shafts, and levers to protect them from impact, dents, and scratches. Use the concealed screw to secure them in place.

These sights have a glass window.

View tank contents from multiple angles through the plastic domed window.

Press these sights into a hole in your tank wall; no additional mounting nuts are needed. They mount from the outside.

Weld these sights to single-wall tanks.

Put an end to water damage from backed-up sewers. When water backs up, the rubber float will rise to seal off the drain. When water recedes, the float will drop for normal drainage.

Add a gasket or replace one that's worn out to ensure a tight seal.

In addition to having a wider temperature range than our other ribbed vibration-damping grommets, these have excellent weather resistance.

In addition to having a wider temperature range than our other vibration-damping washers, these have excellent weather resistance.
