Single-bolt, low-pressure Foreman Isolation Plugs from USA Industries are specially designed to temporarily seal pipe ends during pipeline maintenance or construction. The use of Foreman Isolation Plugs, or Night Caps, help prevent unwanted material such as dirt, water, debris, animals, etc. from entering your pipelines. This is critically important when protecting your expensive pipeline projects.
Foreman Isolation Plugs are made from rugged yet lightweight cast aluminum, which allows most sizes to be easily installed by one person. Foreman Isolation Plugs (Night Caps) come in a variety of sizes, ranging from 4" through 48". This plug is not rated for any back-pressure and should only be used for isolation. For situations involving back-pressure we recommend the GripType pipe plug.
These low-pressure pipe plugs are composed of two aluminum "discs," which are pressed together through the tightening of the central bolt (easily done by one person with a standard wrench). As the discs are pressed together, the surrounding rubber gasket expands, ensuring a tight fit around the inside diameter of the pipe. Foreman Isolation Plugs also come with a removable vent cap, which can be used to release substances that may have accumulated inside the pipe.
When the security of pipe ends is paramount, aluminum Foreman Isolation Plugs (Night Caps) offer incomparable protection.
A SPECIAL WORD OF CAUTION: Pressure testing can be an extremely hazardous operation and safety precautions should be strictly adhered to. All connections, valves, flanges and other fittings should be checked for suitability to test pressure. Verify the line ID & Plug Range match. Most importantly - Never stand or pass in front of any test plug or other enclosure while test is in progress. If plug discharges during a test, serious injury or death could occur.
