ARI CONA Connector – Steam Trap Adapter

The ARI CONA Connector is a fixed piping adapter designed for quick installation and replacement of CONA Universal units. It is not a standalone steam trap; rather, it serves as the connection body for attaching thermostatic, bimetallic, float, or thermodynamic steam trap units.

Versions

• 681: Basic system connector, available with threaded or socket weld connections.
• 682: Connector with external strainer.
• 683: Connector with inlet isolation valve.
• 684: Connector with isolation valves at both inlet and outlet.

Versions 683/684 allow steam trap replacement without disassembling the piping, provided the system is depressurized and properly isolated.

Technical Specifications

• Class: ANSI 300.
• Materials: Forged steel or stainless steel, depending on the version.
• Connections: ANSI 300 RF flanges, R/NPT thread, socket weld, butt weld.
• Limits for SA105 / SA182 F321: up to approximately 464 psi and 752 °F.
• Version 681 from SA351 CF8: up to approximately 420 psi and 752 °F.

Compatible CONA Universal Units

The same connector can accommodate different types of steam traps:

• CONA B Universal: Bimetallic, for subcooled condensate.
• CONA M Universal: Thermostatic capsule.
• CONA S Universal: Float, for immediate discharge of hot condensate.
• CONA TD Universal: Thermodynamic, with or without external strainer.

Applications

Suitable for drainage points where standardization of spare parts, frequent steam trap inspection, or type change without piping modification is required. Selection is based on steam pressure, backpressure, condensate flow, consumer type, material, and connection.

FAQ

When to choose 682?
When an external strainer is required before the steam trap unit.

When to choose 684?
When maintenance requires isolation upstream and downstream from the same connector body.
