Union Hex Nut Design
The Dixon 13H Union Hex Nut uses an external hex configuration that provides flat wrenching surfaces around the fitting. This design allows the nut to be tightened or loosened using an appropriately sized wrench when assembling or servicing a compatible sanitary union connection.
The removable nut configuration supports piping systems where connections may need to be opened for inspection, cleaning, maintenance, or equipment changes. Correct mating components should always be confirmed before installation to ensure the union connection is properly matched.
304 Stainless Steel Construction
The 13H-G100 is manufactured from 304 stainless steel identified by Dixon as CF8. Stainless steel construction provides a durable fitting component for compatible hygienic piping systems and processing environments.
Material compatibility should be evaluated according to the process fluid, cleaning procedure, operating conditions, and requirements of the complete piping system. The nut should be inspected before installation for damage to the threads, hex surfaces, or mating areas.
1 in Tube OD Configuration
This specific 13H-G100 configuration corresponds to a 1 in Tube OD union connection. Selecting the correct tube OD is important because Dixon offers additional 13H union hex nuts for other tube sizes within the product family.
Before ordering, verify that the mating sanitary union components are designed for the same 1 in Tube OD connection and compatible union style. Matching the correct components helps support proper assembly and reduces the possibility of connection mismatch during installation.
Sanitary Piping Applications
Dixon lists the Union Hex Nuts - 13H product family for food and beverage and pharmaceutical markets. The removable union configuration can be useful in sanitary piping installations where equipment and piping components may require periodic access.
Application suitability depends on the complete system. Confirm operating pressure, temperature, media compatibility, mating fitting style, sealing components, cleaning procedures, and applicable sanitary requirements before placing the union into service.
Installation & Selection Considerations
- Confirm the 1 in Tube OD size.
- Verify the required 13H union style.
- Check mating component compatibility.
- Confirm system pressure requirements before use.
- Use appropriate tools when tightening the hex nut.
