Made of steel, these are our most durable plugs for panels. Tapered prongs snap into the hole to securely hold them in place.

Vents in the top allow air circulation and permit heat and fumes to escape. These plugs have tapered prongs that snap into the hole to securely hold 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 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.

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.

Seal tube and hose fittings to keep their straight threads protected from contaminants during fabrication and storage.

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

Safeguard internally threaded BSPT 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.

Also known as mouse tails, these tiny plugs fit through-hole IDs as small as 0.022”, 0.025", or 0.03”.

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.

Sized to fit small openings, these tiny plugs fit snugly but can be removed easily using the flange. Their tapered design fits a range of hole 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.

Place a plug into an opening and tighten the wing nut—the sides expand to create a seal in holes of varying diameters. Good for paint baking and powder-coating applications, these plugs withstand temperatures up to 450° F.

Made of FDA listed materials, these plugs are suitable for food contact. They're tapered to fit a range of hole diameters.

Push these plugs into an opening and friction holds them in place.

Push these plugs into an opening and friction holds them 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.

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

Protect SAE hydraulic flanges during shipping, storing, and finishing applications.

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.

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.

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.

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.

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.

Protect externally threaded components from contaminants during fabrication and storage.

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

Designed for propane tanks such as those on forklifts and grills, these caps protect tank valves during storage and transit. Push the caps onto the valves, then tear their tab to break the seal for easy removal.

Give open-ended standoffs a finished look and protect them from dirt and debris.

A one-piece hinged design allows frequent access to screw heads without misplacing the top. To conceal and protect the entire screw head, insert your screw through the hole in the base and flip the hinged top over.

Sized for knockouts and conduit openings.

Sized for knockouts and conduit openings.

A circular groove quickly centers plug in unused holes and knockouts.
