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.

Also known as mouse tails, these tiny plugs fit hole IDs as small as 0.025". They're commonly used for masking parts during finishing applications. Use the end of the plug to pull it 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.

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.

The large domed head extends beyond the diameter of your pipe, rod, or tubing for added protection.

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

A vibrant yellow color makes these caps stand out. They are made of flexible rubber that conforms for a snug fit. Pull the tab for easy removal.

A ridge on the stem provides a tighter grip than other push-in bumpers. 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.

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 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.

Rated IPX6 and IPX7, these grommets form liquid-tight seals around wire, cable, and cords to protect them against high-pressure washdowns as well as temporary submersion in a maximum of one meter of water. Often used in marine, antenna cable, and lighting cable applications, they can be used outdoors.
