Shop 5000 Straight Female NPT - Female NPT Rigid, Stainless Steel

SAE 140138

The Series 5000-SS Straight Female NPT x Female NPT Rigid adapters in stainless steel are robust fittings designed to connect pipes using NPT (National Pipe Tapered) threads, a U.S. standard widely recognized for over 100 years. These tapered threads create a strong, leak-proof seal by deforming the metal threads during tightening, ensuring efficient fluid and gas transfer. NPT connections are ideal for single-assembly applications and are not intended for frequent disassembly. It is important to avoid over-tightening and use a thread sealant for optimal sealing performance. Made from stainless steel, these adapters are suited for high-pressure systems, offering durable and reliable connections in demanding industrial applications.
