Imperial NPT run tees are precision-engineered fittings designed to connect three lines in a “run” configuration, featuring Imperial National Pipe Taper (NPT) threads. They provide secure, leak-resistant connections for splitting or combining flow while maintaining a straight-through run in instrumentation, hydraulic, and fluid systems.
Widely used across industries such as oil and gas, chemical processing, power generation, and manufacturing, imperial NPT run tees are built for dependable performance in demanding environments. Their tapered NPT threads form a tight seal when installed with proper thread sealant or PTFE tape, ensuring reliable operation in critical process and instrumentation applications.
