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.

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

Good for electroplating, paint baking, and powder-coating applications, these plugs withstand temperatures up to 570° F. All are tapered to fit a range of hole diameters.

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. Their tapered design fits a range of hole diameters.

Flexible ridges or straps hold these plugs in place and allow them to fit 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.

Keep equipment safe from electrical currents with these plugs that have a surface resistivity of less than 10¹² ohms.

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.

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.

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.

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

Keep metal snap-in plugs of various sizes on hand to solve whatever problems arise. Made of steel, these plugs are our most durable plugs for panels. Their tapered prongs snap into holes to securely hold them 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.

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

A long, textured pull tab provides a sure grip for quick removal even when wearing gloves.

The tethered design allows frequent access to the ends of pipe, tubing, and other round objects without ever misplacing the cap.

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

Keep equipment safe from electrical currents with these caps that have a surface resistivity of less than 10¹² ohms.

Made of FDA listed materials, these caps are suitable for food contact.

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.

Protect externally threaded components from contaminants during fabrication and storage.

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.

Unroll these caps onto the tips of cartridges, spouts, and bottles for an airtight seal.

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

Conceal and protect the tops of socket head or button head screws.

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

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