Parker PT-00621 Flareless Bite-type Male Connector 12mm

Product Description

The PARKER PT-00621 is a flareless bite-type tube male connector designed for hydraulic and fluid-conveyance lines where a reliable, vibration-resistant tube-to-port connection is required. The bite-type design uses a ferrule that mechanically bites into the tube OD during assembly, eliminating the need for flared tube ends. This connector accepts a 12 mm tube OD and threads into a 9/16-18 UNF port. It is installed by qualified technicians working on hydraulic systems, fluid power circuits, industrial machinery, and related fluid-handling applications.

This fitting is suited for use in systems that route hydraulic fluid, lubrication oil, or similar media through metal tubing. The 9/16-18 UNF male thread mates with standard UNF-ported components including valves, manifolds, cylinders, and pumps. Sold in a package quantity of five, it is appropriate for maintenance and repair applications where multiple connections may need to be made or replaced at once.

Key Features

• Flareless bite-type ferrule design eliminates the need for tube flaring during assembly
• 12 mm tube OD accommodates standard metric hydraulic tubing
• 9/16-18 UNF male thread for direct connection to UNF-ported hydraulic components
• Compact form factor suited for tight routing and close-quarters installations
• Packaged in quantities of five for efficient maintenance and repair use

Compatibility

Designed as an OEM-style replacement or service fitting for fluid power and hydraulic systems that use 12 mm OD metric tubing with 9/16-18 UNF ported connections.

Installation Notes

Installation should be performed by a qualified hydraulic or fluid power technician. Depressurize and isolate the hydraulic circuit completely before disassembling any fittings or tubing. Ensure tube ends are cut square, deburred, and free of contamination before seating the ferrule. Torque the fitting nut according to the system designer's or tubing manufacturer's specifications — do not over-tighten, as ferrule bite-depth affects seal integrity.
