Male SAE Straight Thread to Female NPT Thread

When it comes to connecting different thread standards in hydraulic and fluid systems, the Male SAE Straight Thread to Female NPT Adapter stands as a reliable and high-performance solution. Designed to bridge the gap between SAE (Society of Automotive Engineers) straight threads and National Pipe Taper (NPT) threads, this adapter ensures secure, leak-free connections in the most demanding environments.

Crafted for durability and accuracy, this fitting is engineered to allow seamless integration between U.S. thread systems—making it a favorite among engineers, technicians, and industrial maintenance professionals.

Features

  • Thread Compatibility: Connects SAE straight threads (ORB – O-Ring Boss) to standard Female NPT threads.
  • Leak-Resistant Design: SAE side typically includes an O-ring for a secure, leak-free seal without the need for PTFE tape or sealant.
  • High Pressure Tolerance: Suitable for high-pressure hydraulic and fluid systems, depending on material and size.
  • Robust Material Options: Available in Stainless Steel (SS 304/316), Brass, Carbon Steel, and custom materials on request.
  • Corrosion Resistance: Ideal for use in harsh environments, especially when made from stainless steel or plated carbon steel.
  • Wide Temperature Range: Handles extreme conditions, depending on material—typically from −65°F to 400°F (−54°C to 204°C) or higher.
