A 45-Degree Angled Male NPT adapter features male NPT (National Pipe Tapered) threads that are offset by 45 degrees from each other, creating a flexible connection option in fluid and gas transfer systems. NPT threads, a U.S. standard used for over 100 years, are tapered to ensure a tight, leak-free seal when the threads are tightened. These adapters are available in various materials, including iron or brass for low-pressure applications and carbon steel or stainless steel for high-pressure systems. The nominal pipe size is determined by measuring the thread diameter and subtracting 1/4". This design is ideal for applications that require angled connections while maintaining secure, effective sealing for fluid and gas transfer. Do not over-tighten. We recommend using a thread sealant with this type of connection style.
