Parker PT-00444 Flareless Bite-type Tube Nut M14x1.5

Product Description

The PARKER PT-00444 is a flareless bite-type tube nut designed for use in hydraulic and fluid conveyance tube fittings. The bite-type design uses a compression ferrule to create a secure, leak-resistant seal without requiring the tube end to be flared before assembly. This nut is sized for an 8 mm tube outside diameter with an M14 x 1.5 metric thread, making it compatible with standard metric bite-type fitting bodies of the same thread specification. It is a small, precision hardware component typically installed by hydraulic technicians, millwrights, and mechanical contractors during tube assembly or field repair work.

This tube nut is suited for metric hydraulic and fluid line assemblies found in industrial equipment, mobile machinery, and mechanical systems that use flareless compression-style tube fittings. The M14 x 1.5 thread pitch is a common metric standard in European-designed and OEM hydraulic circuits. Technicians working on systems that require periodic tube replacement or fitting repair will use this nut as part of a complete bite-type fitting assembly including the fitting body and ferrule.

Compatibility

Designed as an OEM-style replacement or service component for metric flareless bite-type tube fitting assemblies using an 8 mm tube outside diameter and M14 x 1.5 threaded fitting bodies.

Installation Notes

Installation is typically performed by hydraulic technicians or mechanical contractors. De-pressurize and drain the fluid line completely before disassembling any fitting. Ensure the tube is cut square and deburred before seating the nut and ferrule onto the tube end. Follow the fitting manufacturer torque guidance and bite-type assembly procedure to achieve proper ferrule bite and a leak-free seal.
