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

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

Flexible ridges or straps hold these plugs in place and allow them to fit a range of hole diameters.

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

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

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.

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

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.

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

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.

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.

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

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

Commonly used on shipping tubes, these caps have a square head to prevent round objects from rolling during shipping and storage.

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

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

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

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

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.

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.

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.

Tug on the pull tabs to stretch these caps onto the tips of bottles, beakers, flasks, and cylinders, creating an airtight seal.

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

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

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.
