Einhell Double coupling with male thread R3/8"

Original Einhell double coupling with R3/8" male tapered thread will come in handy for a wide variety of work with compressors and pressure hoses that use a 3/8" male thread. The solid brass double nipple with hexagonal fitting serves, for example, as a practical coupling when extending air lines, when building a central compressed air distribution system or as an adapter for direct connection to other equipment. The Einhell coupling makes it easy to use precisely machined and perfectly accurate threads.
