Our Male NPT hydraulic adapters are essential fittings designed to create secure connections in hydraulic systems, utilizing the National Pipe Tapered (NPT) thread style, which is one of the most popular standards in the USA for tapered threads on pipes and fittings. NPT connections are specifically engineered to effectively seal pipes for fluid and gas transfer through a metal-to-metal sealing design, where the threads deform upon tightening to create a secure fit. The nominal pipe size can be determined by measuring the thread diameter and subtracting 1/4". While NPT adapters are ideal for single assembly applications, they are not recommended for frequent disassembly, as this can lead to wear and damage. Care should be taken not to over-tighten these connections, and it is advisable to use a thread sealant to enhance sealing performance. These adapters are vital for professionals seeking reliable and efficient hydraulic solutions in various applications.
