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.

The hollow construction allows these plugs to compress for a snug fit in threaded and unthreaded holes of varying diameters.

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

Lightweight and moisture resistant, these plugs are laboratory-grade 100% natural cork. They’re tapered to fit a range of hole diameters.

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.

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.

Protect internally threaded NPT 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.

Flexible ridges or straps hold these plugs in place.

More durable than plastic plugs, these provide the most protection from abrasion and impact. Use them to eliminate sharp edges and create a finished look on metal fence and machine-guard posts. Drive them in place with a hammer for a secure fit.

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

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

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.

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

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

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

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

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

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

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

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

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

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

Similar to a shower cap, these caps have an elastic band that allows them to stretch and cover a variety of shapes in a range of sizes.

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

Slide these flexible vinyl caps on and they conform for a snug fit. Pull the tab for easy removal.

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

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

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

Snap these caps into flange bolt holes to safeguard pipe flanges during shipping, storing, and finishing applications. They all have a thick center pad to protect the flange opening and pipe threads from damage.

FDA compliant for use near food, these plugs close off unused holes in equipment such as electrical enclosures to keep out debris and water.

Close off unused threaded holes.
