Quantity:
3A certified 13H union hex nut threaded bevel seat

Key Features

  • Premium Material: Forged from AISI 304 or 316L stainless steel for superior corrosion resistance and durability

  • Sanitary Design: Ra < 0.8μm internal surface finish eliminates bacterial crevices, ensuring sterile operation

  • High-Pressure Rating: Engineered to withstand operating pressures up to 400 PSI (size-dependent)

  • Bevel Seat Compatibility: Specifically designed for bevel seat unions, creating a reliable metal-to-metal seal

  • CIP Compatible: Withstands aggressive cleaning agents and high-temperature CIP (Clean-in-Place) cycles without degradation

  • Multiple Sizes Available: Ranging from 1" to 4" (DIN25 to DIN104)

  • Multiple Material Options: Available in SS304 and SS316L

Advantages

  • Leak-Proof Connection: The bevel seat design ensures a high-integrity metal-to-metal seal, minimizing downtime and product loss

  • Extended Service Life: Corrosion-resistant stainless steel withstands harsh processing environments, reducing replacement frequency

  • Easy Installation & Maintenance: Hexagonal shape allows for secure gripping with standard tools, streamlining assembly and disassembly

  • Regulatory Compliance: Fully compliant with 3-A Sanitary Standards, CE, and ISO 9001—eliminating compliance risks for procurement managers

  • Versatile Applications: Suitable for food, beverage, dairy, pharmaceutical, cosmetic, and chemical processing industries

How It Works

The 13H Hex Nut serves as the critical tightening mechanism in bevel seat union assemblies. When threaded onto the tubing, the hexagonal nut draws the threaded bevel seat ferrule and the plain bevel seat ferrule together. This action creates a high-pressure, metal-to-metal seal that prevents leaks and maintains system integrity. The nut's hexagonal shape enables easy torque application using standard wrenches, ensuring consistent and reliable clamping force across all installations.
