Bordo 3/8" x 18 NPT 2" Chrome Button Die

This 3/8" x 18 NPT Chrome Button Die is designed for repairing, restoring, and forming National Pipe Taper (NPT) external threads. NPT threads are widely used throughout plumbing, hydraulics, pneumatics, and general industrial piping systems where a pressure-tight, tapered seal is required.

Key Features:

• Thread Standard: National Pipe Taper (NPT), featuring a tapered thread profile for sealing under pressure.
• Versatile Use:
  • Ideal for chasing and cleaning damaged or corroded tapered pipe threads.
  • Can be used to cut new male NPT threads on non-ferrous metals and plastics.
• Material: Chrome alloy construction suitable for general-purpose threading (not recommended for precision or critical sealing applications).
• Thread Form Details:
  • NPT threads have a 60° thread angle and a tapered profile to create a mechanical seal.
  • Commonly used in fluid and gas systems where leak resistance is essential.
  • Design supports secure engagement as torque increases during assembly.

Technical Specifications:

• Diameter (inch): 3/8
• Pitch (TPI): 18
• Thread Form: NPT
• Outside Diameter: 2"

Applications:

NPT button dies are widely used in plumbing repair, pneumatic and hydraulic maintenance, machinery service, and fabrication work. Their tapered thread profile ensures a reliable sealing action, making them suitable for threaded pipe fittings in both commercial and industrial environments.
