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.

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.

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.

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.

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

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.

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

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.

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.

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.

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

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.

Made of FDA listed materials, these plugs are suitable for food contact. They're tapered 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.

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

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.

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.

A time-saving alternative to threaded plugs, these plugs press in place and have an ergonomic pull tab for quick and easy removal. Use them to temporarily protect holes in objects from contaminants during storage, painting, and light fabrication.

Flexible ridges or straps hold these plugs in place.

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

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.
