Bordo 3/8" x 19 BSPF 2" Chrome Button Die

This 3/8" x 19 BSPF Chrome Button Die is designed for forming, repairing, and restoring British Standard Pipe Parallel (BSPF) external threads commonly used in mechanical coupling and general pipe fitting applications. Its parallel thread profile makes it suitable for applications requiring accurate, non-tapered pipe threads.

Key Features:

• Thread Standard: British Standard Pipe Parallel (BSPF), also known as G-Series pipe thread.
• Versatile Use:
  • Ideal for chasing, restoring, and cleaning damaged or worn external threads.
  • Suitable for cutting new threads on non-ferrous metals and plastics.
• Material: Chrome alloy construction for long service life in general-purpose threading (not suitable for precision or safety-critical applications).
• Thread Form Details:
  • Standard BSPF threads feature a 55° thread angle; some US variations may use 60°.
  • Designed primarily for mechanical coupling applications.
  • Specified according to JIS and ISO R228 standards.

Technical Specifications:

• Diameter (inch): 3/8
• Pitch (TPI): 19
• Thread Form: BSPF
• Outside Diameter: 2"

Applications:

BSPF button dies are widely used in plumbing, machinery maintenance, hydraulic systems, and general engineering where parallel pipe threads are required for secure and consistent mechanical connections.
