Male NPT Clamp Adapter Design
The Dixon 21MP-G250150 combines a sanitary clamp connection with a male NPT threaded connection to provide a transition between compatible sanitary and threaded components. This configuration allows equipment using different connection styles to be incorporated into the same fluid-handling or processing system.
The clamp end provides a removable sanitary connection, while the male NPT end threads into compatible female NPT equipment or piping. Both connection styles should be confirmed before installation to ensure the adapter matches the intended system arrangement and mating components.
304 Stainless Steel Construction
The 21MP-G250150 is manufactured from 304 stainless steel for use in compatible sanitary and hygienic processing environments. Its stainless steel construction provides a durable adapter body for applications where cleanliness, corrosion resistance, and routine system cleaning are important considerations.
Material compatibility should be evaluated against the process media, cleaning chemicals, operating conditions, and surrounding equipment. Confirm that 304 stainless steel meets the requirements of the complete installation before placing the adapter into service.
2-1/2 in Clamp x 1-1/2 in Male NPT Configuration
The Dixon 21MP-G250150 features a 2-1/2 in tube OD configuration paired with a 1-1/2 in male NPT thread and a 2.781 in A dimension. These specifications help identify the correct adapter when transitioning from compatible sanitary clamp equipment to a smaller threaded system connection.
Tube OD, NPT thread size, and available installation space should all be confirmed before ordering. Verify the mating female NPT component and sanitary clamp connection so the adapter can be properly incorporated into the intended piping or processing assembly.
Sanitary & Hygienic Processing Applications
The Dixon 21MP-G250150 provides a transition between compatible sanitary clamp equipment and NPT threaded components in food, beverage, pharmaceutical, and other hygienic processing applications. Its configuration is useful where a 2-1/2 in sanitary connection must transition to a smaller 1-1/2 in threaded connection.
Final system suitability depends on the mating fittings, clamp components, gasket selection, female NPT connection, process media, cleaning procedures, operating conditions, and material compatibility of the complete assembly. All system components should be reviewed together before installation.
Installation & Selection Considerations
- Verify part number 21MP-G250150.
- Confirm the required 2-1/2 in tube OD.
- Verify the 1-1/2 in male NPT thread.
- Confirm the 2.781 in A dimension.
- Verify 304 stainless steel is suitable for the application.

Our fitting specialists can help review your Dixon part number, tube OD, NPT thread size, adapter dimension, 304 stainless steel construction, clamp compatibility, mating threaded component, and application requirements before you order.
