These fittings are equipped with 1/4 inch NPT (National Pipe Thread) threads on both ends, which are tapered and threaded to ensure a leak-free connection when used with compatible pipe threads. The threads are also compatible with other threaded fittings, valves, and pipes, allowing for versatile piping configurations.
