Parker PT-00446 Flareless Bite-type Tube Nut M16x1.5 Steel

Product Description

The PARKER PT-00446 is a flareless bite-type tube nut designed for use in high-pressure hydraulic and fluid power tube assemblies. This steel nut threads onto an M16x1.5 metric fitting body and works in conjunction with a bite-type sleeve to create a secure, leak-resistant connection without the need to flare the tube end. Rated to 500 bar maximum working pressure, it accommodates a 10 mm tube outside diameter and measures 15.5 mm in overall length. Licensed hydraulic technicians and fluid power specialists install this component in industrial and mobile hydraulic systems where reliable tube retention under pressure is required.

This tube nut is suited for metric hydraulic tube assemblies in industrial machinery, mobile equipment, and fluid power circuits where flareless bite-type connections are specified. The M16x1.5 metric thread engagement is common in European-standard and ISO-compliant hydraulic plumbing configurations. It is typically installed during new assembly or as a service replacement when a fitting nut is damaged or cross-threaded during field maintenance.

Key Features

• Flareless bite-type design eliminates the need for tube flaring during assembly
• Rated to 500 bar maximum working pressure for demanding hydraulic applications
• M16x1.5 metric thread size conforms to standard metric hydraulic fitting dimensions
• Fits 10 mm tube outside diameter
• Steel construction provides strength and durability in high-pressure service
• 15.5 mm overall length fits standard bite-type fitting body configurations

Compatibility

Designed as an OEM-style replacement or service component for metric flareless bite-type tube fitting assemblies using a 10 mm tube OD and M16x1.5 thread engagement.

Installation Notes

Installation is performed by qualified hydraulic technicians or fluid power specialists. Depressurize and isolate the hydraulic circuit completely before disassembling any tube fitting. Follow the fitting manufacturer's assembly procedure for bite-type connections, including proper pre-swaging of the sleeve before final torque, as overtightening or undertightening a bite-type nut can compromise the seal. Reference applicable system schematics and industry standards such as ISO 8434 for metric flareless fitting assembly practices.
