2-1/2" threaded couplings are used to join two ends of 2-1/2” threaded rigid conduits or IMC conduits together. They can also be used with chase nipples and connectors to bond threaded conduits to electrical junction boxes or enclosures. Garvin Industries’ versatile threaded design works with all standard threaded connectors. These couplings are often used as a component to convert flexible metal conduits to EMT thinwall, rigid conduit, or liquid tight conduits by using the related threaded connectors.
