Our Female NPT Cross adapters are essential fittings used in hydraulic and fluid power systems to connect four components in a cross-shaped layout. These adapters feature female NPT (National Pipe Tapered) threads, which are a widely used USA standard for tapered threads that ensure a tight, leak-proof seal. NPT connections rely on thread deformation, where the male and female threads form a metal-to-metal seal, making them ideal for single assembly applications. Female NPT Cross adapters are designed to provide reliable fluid transfer in high-pressure systems, offering flexibility in routing fluid between multiple components. Due to the tapered design, it's important not to over-tighten and to use thread sealant for enhanced sealing. These adapters are typically used in industrial applications where secure, long-lasting connections are required, offering durability, corrosion resistance, and efficient fluid routing for demanding environments.
