Radium Engineering one-way check valve fitting adapts a female 6AN ORB port to a male 10mm hose barb, supplying directional flow control for lines that require a larger barb size. The fitting screws into a 6AN ORB port and provides a 10mm hose connection, offering a straightforward solution when a one-way valve function is needed between AN-style threads and 10mm hose systems.
