Parker 8 Tu-s Flareless Bite-type Tube Ferrule 0.5 in Steel

Product Description

The PARKER 8 TU-S is a flareless bite-type tube ferrule designed for use in hydraulic and instrumentation tube fitting assemblies. It creates a secure, leak-resistant mechanical connection by biting into the outer wall of the tube as the fitting nut is tightened — eliminating the need for flaring the tube end. Constructed from steel, this ferrule measures 0.43 inches in overall length and fits a 0.5 inch tube outer diameter. It is compatible with 24-degree flareless fitting systems and is sized as a Size 8 component. Licensed plumbers, pipefitters, and instrumentation technicians install this type of ferrule in both industrial and commercial fluid system applications.

This ferrule is suited for use in hydraulic lines, pneumatic circuits, and instrumentation tubing runs where a reliable, vibration-resistant connection is required without tube flaring. It is commonly installed in commercial and industrial settings, including process piping, fluid power systems, and control tubing assemblies. The steel construction makes it appropriate for applications with moderate to high system pressures where material strength is a factor in fitting selection.

Key Features

• Flareless bite-type design eliminates the need for tube flaring during assembly
• Fits 0.5 inch tube outer diameter with Size 8 designation
• Steel construction for durability in hydraulic and pneumatic service
• 24-degree flared angle for compatibility with standard flareless fitting bodies
• 0.43 inch overall length for compact installation in tight tubing runs

Compatibility

Designed as an OEM-style replacement or service ferrule for use with PARKER flareless bite-type fitting bodies and nuts rated for 0.5 inch tube outer diameter in 24-degree flareless fitting systems.

Installation Notes

Installation of bite-type ferrules should be performed by a licensed pipefitter, hydraulic technician, or instrumentation technician familiar with flareless fitting assembly procedures. Depressurize and isolate the system completely before disassembling any tube fittings. Follow the fitting manufacturer's prescribed presetting procedure to ensure proper ferrule bite — do not overtighten, as this can deform the ferrule and compromise the seal. Verify tube end squareness and cleanliness before assembly.
