Product Features• A low-pressure, ported test plug
Need a quick and easy seal on your pipe, tube or round hole? USA Industries' Wing Nut Isolation Plugs are just what you're looking for. These plugs use neoprene seals with die cast bodies and are available in line sizes from 2" through 24". Also known as a Plumber's Type Plug, this plug is rated to hold back pressure up to 13 PSIG, and it is available with or without upstream venting capabilities.
Designed and developed for testing for leaks and for sealing off sections of pipelines generally made of cast iron, steel, vitrified clay, concrete, etc., these wing nut plugs come with a vent tube for venting excess back-pressure. One person can easily install these plugs. Turning the wing nut expands the rubber ring tightly against the inside of the pipe. Hand-tightening is usually adequate in smaller sizes, but a wrench can be used on larger sizes to give a better seal.
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.
