Female NPT Clamp Adapter Design
The Dixon 22MP-R400 combines a sanitary clamp connection with a female 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 female NPT end accepts compatible male NPT equipment or piping. Both connection styles should be confirmed before installation to ensure the adapter matches the intended system arrangement and mating components.
316L Stainless Steel Construction
The 22MP-R400 is manufactured from 316L 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 316L stainless steel meets the requirements of the complete installation before placing the adapter into service.
4 in Clamp x 4 in Female NPT Configuration
The Dixon 22MP-R400 features a 4 in tube OD configuration paired with a 4 in female NPT thread and a 2.63 in A dimension. These specifications help identify the correct adapter when transitioning from compatible sanitary clamp equipment to a same-size threaded system connection.
Tube OD, NPT thread size, and available installation space should all be confirmed before ordering. Verify the mating male 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 22MP-R400 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 4 in sanitary connection must transition to a same-size 4 in female threaded connection.
Final system suitability depends on the mating fittings, clamp components, gasket selection, male 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 22MP-R400.
- Confirm the required 4 in tube OD.
- Verify the 4 in female NPT thread.
- Confirm the 2.63 in A dimension.
- Verify 316L stainless steel is suitable for the application.

Our fitting specialists can help review your Dixon part number, tube OD, NPT thread size, adapter dimension, 316L stainless steel construction, clamp compatibility, mating threaded component, and application requirements before you order.
