The PARKER PT-00653 is a flareless bite-type tube male connector designed for use in hydraulic and fluid conveyance systems where a secure, leak-resistant tube-to-port connection is required without flaring the tubing. The fitting features a 6 mm tube outside diameter (OD) and a M10x1 metric male thread, making it suited for metric plumbing systems common in industrial, mobile hydraulic, and mechanical installations. The bite-type design uses a ferrule or sleeve that bites into the tube wall on assembly, creating a strong mechanical grip and seal. This connector is typically installed by mechanical or fluid power technicians.
This fitting is used in metric fluid line assemblies where a male threaded port connection is required. Common applications include hydraulic systems, pneumatic circuits, and coolant or oil lines in industrial machinery and mobile equipment. The M10x1 thread pitch and 6 mm tube OD make it compatible with metric component systems found in European-designed equipment and machinery. It is sold in a package quantity of 5 units.
Designed as a replacement or service fitting for metric fluid systems requiring a flareless bite-type male connector with a 6 mm tube OD and M10x1 thread. Confirm thread pitch, tube OD, and system pressure rating before installation.
Installation is typically performed by a licensed fluid power or mechanical technician. Depressurize and drain the fluid line completely before disassembling any fittings. Ensure the tube end is cut square and deburred before inserting into the fitting body, as surface irregularities can compromise the bite-type seal. Torque the fitting nut to the equipment manufacturer's specified value; do not over-tighten, as this can damage the ferrule and tubing.
