Often used as laboratory stoppers, these rubber plugs have good impact and abrasion resistance. They’re tapered to fit a range of hole diameters.

Keep hollow tapered plugs of various sizes on hand to solve whatever problems arise. The hollow construction allows these plugs to compress for a snug fit in threaded and unthreaded holes of varying diameters.

Pull the two built-in rings to quickly remove these plugs. All are tapered to fit a range of hole diameters.

Often used on gas cylinders, these plugs cinch and lock tightly around valve heads to block the ports—they must be cut off making it clear if the cylinder has been tampered with. The plugs are tapered to fit a range of hole 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.

Sized to fit small openings, these tiny plugs fit snugly but can be removed easily using the flange. They withstand temperatures up to 470° F, which makes them good for electroplating, paint baking, and powder-coating applications. All are tapered to fit a range of hole diameters.

These plugs have excellent chemical resistance for masking parts during chemical finishing applications such as plating and anodizing. Use the smaller end of the plug to pull the larger end into a through hole to form a tight seal.

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.

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.

With a surface resistivity of less than 10⁵ ohms, these plugs not only dissipate electrical charges, but can be used as an electrical shield.

Flexible ridges or straps hold these plugs in place and allow them to fit a range of hole diameters.

These plugs withstand temperatures up to 600° F to protect internally threaded NPT connections from contaminants during electropainting, paint baking, and powder coating applications.

Designed to fit into 37° flared connections such as those found on JIC and SAE fittings, these plugs protect internally threaded connections from contaminants during fabrication and storage.

Flexible ridges or straps hold these plugs in place.

Flexible ridges securely hold these plugs in place and allow them to fit a range of hole sizes.

Tapered prongs or a snap-in ring securely hold these plugs in place.

The wings on these plugs expand against the sides of a hole to lock them in place.

Vents in the top allow air circulation and permit heat and fumes to escape. All of these plugs have wings that expand against the sides of the hole to lock them in place.

Slide these flexible vinyl caps on and they conform for a snug fit.

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

Slide these caps over a tool handle or other round object and use the eye to hang it.

Commonly used on shipping tubes, these caps have a square head to prevent round objects from rolling during shipping and storage.

These caps have excellent chemical resistance for masking parts during chemical finishing applications such as plating and anodizing.

With a surface resistivity of less than 10⁵ ohms, these caps not only dissipate electrical charges, but can be used as an electrical shield.

These flexible plastic caps are tapered to fit a variety of unthreaded and threaded objects.

Keep tapered caps of various sizes on hand to solve whatever problems arise. These flexible plastic caps are tapered to fit a variety of unthreaded and threaded objects.

Made of rigid plastic, these caps are more wear resistant than vinyl caps but not as flexible.

Guard the corners of fragile materials such as glass and mirrors.

Made of rigid plastic, these caps provide more wear resistance to the ends of angle iron than vinyl caps but are not as flexible.

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.

Push these caps onto pipe and fittings, then tear their tab to break the seal for easy removal.

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

Squeeze the dome top to remove these caps. They're commonly used as thread protectors.

Sized to fit hex nuts, these caps snap on for a tight hold and provide protection from corrosion.

To conceal and protect the entire screw head, insert your screw through the hole in the base and snap on the top.

Stretch these caps over flared edges such as flanged tubing and valve handles.

Stick these caps on the raised surfaces of flanges or other flat surfaces for extra protection during transport and storage.
