Parker PT-00447 Flareless Bite-type Tube Nut M16x1 12mm

Product Description

The PARKER PT-00447 is a flareless bite-type tube nut designed for use in hydraulic and pneumatic tubing assemblies. This metric nut accepts a 12 mm tube OD and features an M16 x 1 thread, providing a secure, leak-resistant connection without the need for flared tube ends. The bite-type design uses a cutting ring or ferrule to grip the tube wall mechanically as the nut is tightened, creating a robust seal suitable for high-pressure fluid and instrumentation lines. Installation is typically performed by licensed fluid power technicians, pipefitters, or industrial mechanics working on hydraulic circuits, instrumentation systems, or process piping.

This fitting nut is suited for metric tube assemblies in industrial, commercial, and mobile hydraulic applications. It is commonly installed in systems where flareless compression-style connections are specified, including hydraulic power units, machine tool circuits, and fluid instrumentation lines. The M16 x 1 thread pitch is a fine-pitch metric standard frequently found in European-designed machinery and imported industrial equipment. Sold in a package quantity of four, this nut is appropriate for multi-connection service work or initial system assembly.

Key Features

• Flareless bite-type design eliminates the need to flare tubing prior to assembly
• M16 x 1 fine-pitch metric thread for secure nut engagement
• Accepts 12 mm tube OD for compatibility with metric hydraulic and instrumentation tubing
• Package quantity of four nuts supports multi-connection installations
• Compact, lightweight construction suited for tight-space hydraulic plumbing

Compatibility

Designed as an OEM-style replacement or service component for flareless bite-type tube fitting assemblies requiring an M16 x 1 thread and 12 mm tube OD. Intended for use with compatible Parker bite-type cutting rings and fitting bodies of matching metric specification.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with flareless compression fitting assembly procedures. Depressurize and lock out the hydraulic or pneumatic system completely before disassembling any tube connections. Follow the fitting manufacturer's pre-swaging or hand-tightening procedure to ensure the cutting ring seats correctly before final torque is applied — do not over-drive the nut or substitute mismatched ferrules. Applicable systems may be subject to local hydraulic piping codes and machine safety standards; verify system pressure ratings before returning the circuit to service.
