The MIDLAND INDUSTRIES SA-400-SS is a Type AA cam and groove spool adapter designed for industrial hose and fluid transfer applications. It features dual 4-inch male adapter ends, allowing two cam and groove fittings to be joined end-to-end in a spool configuration. Constructed from 316 stainless steel, this adapter is built to handle a wide operating temperature range of -150 to 500 degrees F, making it suitable for demanding chemical, agricultural, petroleum, and industrial process environments. Plumbers, pipefitters, and industrial maintenance technicians install this type of fitting as part of quick-disconnect hose systems.
This spool adapter is used in industrial fluid transfer systems where a male-to-male cam and groove connection is required between two female coupler ends. Typical applications include tank truck loading and unloading, chemical processing lines, agricultural irrigation systems, and general industrial hose assemblies. The Type AA designation indicates a male adapter on both ends, making it a standard spool piece in cam and groove hose fitting systems. Its stainless steel construction makes it a preferred choice in corrosive or high-temperature service environments.
Designed as an OEM-style replacement or direct-use Type AA cam and groove spool adapter compatible with standard 4-inch female cam and groove couplers in industrial hose fitting systems.
Installation is typically performed by pipefitters or industrial mechanics familiar with cam and groove quick-disconnect systems. Depressurize and drain the line completely before disconnecting or installing any cam and groove fittings. Confirm that the connected female couplers and gaskets are rated for the same temperature and chemical compatibility as the service application. Follow applicable industry standards and facility safety protocols when working with pressurized fluid transfer lines.
