Parker PT-00449 Flareless Bite-type Tube Nut M30x2 22mm

Product Description

The PARKER PT-00449 is a flareless bite-type tube nut designed for use in hydraulic and fluid conveyance systems where a flare-free, compression-style tube connection is required. This metric nut threads onto an M30 x 2 fitting body and is sized for a 22 mm tube outside diameter. Bite-type fittings use a ferrule or sleeve that bites into the tube wall under torque, creating a leak-resistant mechanical seal without the need to flare the tube end. Technicians and pipefitters working on hydraulic lines, industrial fluid circuits, or high-pressure plumbing assemblies will encounter this style of fitting in both OEM and service applications.

This tube nut is suited for metric bite-type fitting assemblies used in industrial, mobile hydraulic, and fluid power systems. It is the threaded retaining component that captures the ferrule and drives it against the fitting body during assembly. Applications include hydraulic power units, machine tool plumbing, and other systems where metric tube connections are specified. The M30 x 2 thread designation indicates a 30 mm nominal thread diameter with a 2 mm thread pitch, standard in many European-origin and ISO-spec hydraulic systems.

Key Features

• Flareless bite-type design eliminates the need for tube flaring during assembly
• M30 x 2 thread size suits ISO and metric hydraulic fitting bodies
• Sized for 22 mm tube outside diameter
• Sold in a package quantity of 4 nuts per pack
• PSC code 4720, consistent with hose, pipe, and tube fittings classification

Compatibility

Designed for use with flareless bite-type fitting bodies accepting an M30 x 2 nut thread and a 22 mm tube outside diameter, consistent with DIN 2353 and ISO 8434-1 style compression fitting assemblies.

Installation Notes

Installation of bite-type tube fittings is typically performed by hydraulic system technicians or pipefitters. Depressurize and isolate the hydraulic or fluid circuit completely before disassembling or replacing any fitting component. Pre-swage the ferrule onto the tube using the correct presetting tool before final assembly where required by the fitting manufacturer. Do not over-torque the nut, as excessive force can damage the ferrule or tube wall and compromise the seal.
