2507 super duplex threaded plugs – AODSON 2507 super duplex threaded plugs use an external hex head for wrench installation and a short male-threaded body for closing equipment ports. Dimensions, thread form, shoulder and sealing interface are manufactured to the approved standard or customer drawing.

Application and Interface Review
Thread designation alone does not define sealing performance. Specify metric, BSPP, BSPT, NPT or UN thread, engagement length, shoulder geometry, gasket or seal arrangement, pressure and process medium. The equipment designer must confirm thread compatibility and tightening requirements.
Key Product Features
- External hex head for positive tool engagement
- Metric, BSP, NPT and UN thread options
- Custom shoulder and sealing-face geometry
- Permanent material or batch marking available
Materials and Manufacturing
CNC turning controls the thread, shoulder and sealing face while milling or bar geometry forms the external hex. Deburring protects the mating port and seal. Passivation, identification and protective packaging are applied as specified.
The proposed route is CNC turning, hex machining, thread production, marking and passivation. Final material, dimensions, tolerances, finish and testing remain subject to the approved drawing and purchase specification.
Typical Applications
- Pump and valve bodies
- Hydraulic and process manifolds
- Desalination and seawater equipment
- Chemical processing systems
Quality Control and Approval
Inspection may include material certification, PMI, thread gauges, sealing-face dimensions, concentricity and surface condition. Pressure testing applies only when the plug is assessed within a defined mating assembly and test procedure.
