Connectors

Steam trap connectors are installed as permanent line components to allow installation, removal, and replacement of steam traps without modifying the steam line. Typical services include steam tracing, line drip points, trap stations, small heat exchangers, condensate headers, and locations where periodic inspection or replacement of the drain element is required. A connector is not a steam trap by itself; it provides the mounting interface for compatible thermostatic, bimetallic, thermodynamic, or float trap modules.

This category includes ARI CONA Connector and Gestra Universal connector designs. The ARI CONA Connector is available with threaded connections, an integral Y-type strainer, an inlet isolation valve, or isolation valves on both inlet and outlet, with optional blowdown arrangement for strainer cleaning or functional checking. Selection is based on steam pressure, back pressure, condensate load, trap operating principle, body material, installation orientation, and the requirement for line isolation during maintenance.

In planned maintenance programs, the connector reduces intervention time and limits repeated disassembly of threaded joints, flanges, and auxiliary fittings. Inspection points include the strainer screen, gaskets, sealing faces between connector and trap, isolation valves, and any blowdown device fitted. Available configurations include ANSI Class 300, raised-face flanges, R or NPT threads, socket weld, and butt weld ends. Typical materials include forged carbon steel and stainless steel grades such as SA105, SA182 F321, and SA351 CF8, selected according to pressure-temperature rating, condensate chemistry, and corrosion allowance.
