Twist the easy-grip T-handle on these plugs to expand the seal.

Turn the square head of the plug into the sealing ring to close off pipe openings.

Also known as pneumatic plugs, these plugs conform to wide and out-of-round pipes.

These extra-long plugs allow you to seal off two pipes at the same time. They have two separate inflation chambers to release back pressure gradually and prevent splash back as water clears the drain line.

Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve back pressure while testing.

Use the bypass tube to add air, water, and fluid or relieve back pressure.

Tighten these threaded fittings with your hands for a secure connection in testing, flushing, venting, and plugging applications—no tools, tape, or sealant required.

Seal unthreaded pipe ends with these plugs. They come with a band that clamps over the outside wall of your pipe and tightens with a screwdriver.

Create an access point to inspect and clean a floor drain pipeline.

Made of polypropylene, these gravity-flow fittings withstand organic solvents, such as acetone, that would dissolve CPVC pipe. They also stand up to highly corrosive acids, such as hydrochloric acid, and alkalies.

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.

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.

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.

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.

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.

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

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

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.

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.

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.

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

Often used on metal furniture, these plugs provide a finished look on posts and tubes. Snap them into place and their flexible ridges will provide a secure grip.

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

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

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

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

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

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

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

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

Slide these flexible vinyl caps onto rectangular objects and they conform for a snug fit.

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

Place these flexible vinyl caps over the ends of your angle iron and they conform for a snug fit.

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.

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.

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.

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.

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