Metal Round Caps

More durable than plastic caps, these provide the most protection from abrasion and impact.
Steel caps are stronger than aluminum.
Aluminum caps have good corrosion resistance, are lightweight, and are nonmagnetic.
Stainless steel caps have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.

Air-Inflatable Plugs
Conform to wide and out-of-round pipes with these inflatable plugs. Also known as pneumatic plugs, they're designed for temporary seals since they can lose pressure over time. Inflate with a hand pump (sold separately); an air compressor may overinflate the plug and cause damage. Tether the plugs using either the eyebolt or chain/ring so they don't get lost or stuck in your pipes. Maximum air back pressure is the amount of pressure a plug can withstand without moving. Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.
