The PARKER PT-00519 is a flareless bite-type tube swivel nut run tee designed for use in hydraulic and fluid conveyance systems where a metric threaded, inline tee connection is required. The fitting features an M22x1.5 metric thread and accepts 15 mm outside diameter tubing. Bite-type flareless construction allows the ferrule to bite into the tube wall during assembly, creating a secure, leak-resistant seal without the need to flare the tube end. This style of fitting is commonly installed by hydraulic system technicians, industrial maintenance personnel, and fluid power specialists working on equipment that requires reliable inline branching of a tube run.
This swivel nut run tee is suited for inline tee configurations in hydraulic circuits, fluid transfer lines, and related industrial piping systems using metric tubing. The swivel nut design allows the nut to rotate independently of the fitting body during installation, which simplifies assembly in tight or awkward spaces where rotating the entire fitting is not practical. The M22x1.5 metric thread size is common in European-standard and metric hydraulic equipment.
Designed for use with 15 mm outside diameter tubing and M22x1.5 metric threaded ports in flareless bite-type hydraulic and fluid conveyance systems.
Installation should be performed by a qualified hydraulic or fluid power technician familiar with flareless bite-type fitting procedures. Depressurize and isolate the hydraulic circuit fully before disassembling any line connections. During assembly, advance the swivel nut to the correct engagement depth per the bite-type fitting procedure to ensure the ferrule seats properly without over-tightening. Verify thread engagement and inspect for leaks before returning the system to service.
