Parker PT-00445 Flareless Bite-type Tube Nut M12 X 1.5

Product Description

The PARKER PT-00445 is a flareless bite-type tube nut designed for use in hydraulic and fluid-conveying tube assemblies. This nut is the mating threaded component in a flareless bite-type fitting system, working alongside a body and ferrule to create a leak-resistant mechanical connection without requiring a flared tube end. It accepts an 8 mm outside diameter tube and threads onto a fitting body with an M12 x 1.5 metric thread. Flareless bite-type connections are widely used in high-pressure hydraulic lines, instrumentation tubing, and fluid system plumbing across industrial and mobile equipment. Installation is performed by qualified hydraulic or fluid system technicians.

This tube nut is suited for metric tube assemblies requiring a compact, reliable bite-type grip connection. Typical applications include hydraulic control circuits, coolant and lubrication lines, and instrumentation manifold plumbing where metric fittings are specified. The M12 x 1.5 thread pitch is a standard metric coarse-pitch designation common in European-style hydraulic systems. Sold in a package of four nuts, this SKU is practical for bench-stocking or small assembly jobs requiring multiple connections of the same size.

Key Features

• Flareless bite-type design eliminates the need for tube end flaring before assembly
• 8 mm tube outside diameter compatibility suits standard metric hydraulic and instrumentation tubing
• M12 x 1.5 metric thread for engagement with matching Parker bite-type fitting bodies
• Package quantity of 4 nuts supports multi-connection jobs or bench stock replenishment
• Compact nut geometry suited for installations with limited wrench clearance

Compatibility

Designed for use in Parker flareless bite-type fitting assemblies accepting 8 mm outside diameter tubing with an M12 x 1.5 threaded fitting body. Consult the specific Parker fitting series documentation to confirm body and ferrule pairing before installation.

Installation Notes

Flareless bite-type tube nuts are installed by hydraulic technicians familiar with metric fitting assembly procedures. Before any fitting work, relieve all system pressure and depressurize the fluid circuit completely. Assemble the nut and ferrule onto the tube and thread onto the fitting body by hand before applying a wrench; follow the applicable Parker presetting procedure to seat the ferrule correctly on initial assembly. Do not reuse ferrules that have already been set on a tube, as the bite engagement is a one-time deformation.
