Adaptor - Reducing Bush - NPT x NPT - SAE Specification

A Reducing Bush Adaptor (NPT x NPT) under SAE-compatible specifications is a threaded fitting used to connect two different-sized NPT (National Pipe Tapered) threads, typically reducing from a larger female port to a smaller male thread.

• Thread Type: NPT (National Pipe Tapered), conforming to ASME B1.20.1
• Seal Type: Tapered thread seal via thread deformation; requires PTFE tape or pipe thread sealant
• Material Options:
  • 316 Stainless Steel (e.g., SS-5406 series) 
  • Carbon Steel, Brass, and specialty alloys (e.g., Alloy 625, 825, 2507) 
• Pressure Rating: Varies by size and material, typically up to 10,000 psi
• Temperature Range:
  • Stainless Steel: Up to 1000°F (537°C)
  • Carbon Steel: Up to 375°F (190°C)
• SAE Compatibility: While NPT is not an SAE thread, it is widely used in SAE J514-compliant systems and is referenced in SAE J476 for thread standards
