Shop 5404 Straight Male NPT - Male NPT Hex Nipple
SAE 140137
The Series 5404 Straight Male NPT x Male NPT Hex Nipple hydraulic adapters, constructed from durable carbon steel, are designed to create secure connections for fluid and gas transfer in hydraulic systems. These adapters utilize the National Pipe Taper (NPT) standard, featuring tapered threads that ensure a reliable seal through thread deformation, forming a strong metal-to-metal connection when tightened. The nominal pipe size can be easily determined by measuring the thread diameter and subtracting 1/4". NPT connections have been widely used in the U.S. for over 100 years and are ideal for single assembly applications, although they are not recommended for frequent disassembly due to potential wear on the threads. The hex nipple design allows for easier installation and tightening, making these adapters an excellent choice for professionals seeking efficient and dependable hydraulic solutions in various applications.
