Parker PT-00443 Flareless Bite-type Tube Nut M12 X 1.5

Product Description

The PARKER PT-00443 is a flareless bite-type tube nut designed for use in hydraulic and instrumentation tube fitting assemblies. It threads onto a mating fitting body at M12 x 1.5 thread size and secures a 6 mm outside-diameter tube in place, working in conjunction with a bite-type sleeve or ferrule to create a leak-resistant mechanical connection without requiring the tube end to be flared. This style of nut is a standard component in flareless compression-style fitting systems and is typically installed by hydraulic system technicians, industrial pipefitters, or instrumentation mechanics.

This tube nut is suited for use in hydraulic lines, fluid power circuits, and instrumentation tubing runs where a flareless connection is specified. It is commonly found in industrial equipment, mobile hydraulic systems, and process control applications that call for metric M12 x 1.5 fittings with 6 mm tube OD. It is packaged in a quantity of four per pack, making it practical for service kits or multi-point installations.

Key Features

• M12 x 1.5 metric thread for precise mating with standard flareless fitting bodies
• 6 mm tube OD compatibility for use with common metric instrumentation and hydraulic tubing
• Flareless bite-type design eliminates the need for flaring the tube end before assembly
• Packaged in a quantity of four, suitable for multi-connection jobs or stocking
• Compact, low-profile nut geometry for installations in tight spaces

Compatibility

Designed as an OEM-style replacement or service component for flareless bite-type fitting assemblies requiring an M12 x 1.5 nut with 6 mm tube OD, consistent with standard metric tube fitting systems.

Installation Notes

Installation should be performed by a qualified hydraulic or instrumentation technician following the fitting manufacturer's assembly procedure. Depressurize and isolate the hydraulic or fluid circuit completely before disassembling any fitting. The bite-type sleeve must be properly seated on the tube before the nut is torqued to the fitting body. Do not reuse a bite sleeve that has already been swaged onto a tube, as this can compromise the seal integrity.
