The Superlok Series IHLN Straight Male NPT x Male NPT Instrumentation Hex Long Nipple hydraulic adapters, crafted from durable stainless steel, are designed to provide secure connections in hydraulic systems, particularly for instrumentation applications. These adapters feature male NPT (National Pipe Taper) threads, which utilize a metal-to-metal sealing design that relies on thread deformation to ensure a reliable seal for fluid and gas transfer when tightened. The nominal pipe size can be identified by measuring the thread diameter and subtracting 1/4". While NPT connections are ideal for single assembly applications, they are not recommended for frequent disassembly due to potential wear on the threads. Available in varying lengths, these hex long nipple adapters are perfect for professionals seeking compact, dependable, and efficient solutions for fluid and gas transfer in instrumentation systems.
