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.

Lightweight and moisture resistant, these plugs are laboratory-grade 100% natural cork. They’re 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.

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

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

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

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.

Protect internally threaded NPT connections from contaminants during fabrication and storage.

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

Safeguard internally threaded BSPT connections from contaminants during fabrication and storage.

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.

These plugs are see-through to provide visibility and light transmission. They have wings that expand against the sides of the hole to lock them in place.

Push these plugs into place for a finished appearance on both sides of a panel.

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.

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.

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

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.

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.

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.

Permanently seal pipe, tubing, conduit, and even crimped electrical connections. Slide these flexible caps on and use a heat gun to tightly shrink them to the shape of whatever they are covering. Their outer surface shrinks while the inner wall flows into voids to create a sealed connection.

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

Push these caps onto pipe and fittings, 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.

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