Twist the wing nut on these plugs to expand the seal.

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.

Fill your air-inflatable plugs with these lightweight hand pumps.

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

Manually pump air, water, or hydraulic fluid through your system so you can test for leaks.

Easier to use than manual pumps, these use electricity to quickly pump water through your system so you can test for leaks.

Often used as laboratory stoppers, these rubber plugs have good impact and abrasion resistance. They’re 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.

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.

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.

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

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.

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.
