Parker PT-00145 Bite-type Tube Ferrule 1/8 in Steel

Product Description

The PARKER PT-00145 is a flareless bite-type tube ferrule designed to form a leak-resistant seal on instrument and fluid-system tubing without the need for flared tube ends. The ferrule bites into the outer wall of the tube as the fitting is tightened, creating a mechanical grip and pressure-tight connection. Constructed from steel, this ferrule measures 0.29 inches overall length and is sized for 1/8 inch tube outside diameter. It is a standard component in compression-style tube fitting assemblies used across hydraulic, pneumatic, and instrumentation systems. Installation is performed by qualified pipefitters, plumbers, and instrumentation technicians.

This ferrule is suited for use in low-to-medium pressure tubing runs found in residential and light commercial HVAC controls, refrigeration instrumentation lines, hydraulic control circuits, and industrial pneumatic systems. The flareless design makes it practical in field applications where flaring tools are not available or tube end access is limited. Packaged in quantities of five, it is appropriate for service kits and small-volume repair work.

Key Features

• Flareless bite-type design eliminates the need for tube flaring during assembly
• Sized for 1/8 inch tube outside diameter for consistent compression fit
• Steel construction provides durability in moderate-pressure fluid and pneumatic lines
• 0.29 inch overall length fits standard compression fitting bodies designed for this tube OD
• 24-degree flared angle conforms to standard flareless fitting geometry
• Packaged in quantities of five for service and repair use

Compatibility

Designed as an OEM-style replacement ferrule for use with standard flareless compression tube fittings accepting 1/8 inch outside diameter tubing.

Installation Notes

Installation is performed by a qualified pipefitter or instrumentation technician. Depressurize and isolate the tubing circuit completely before disassembling any fitting. The ferrule is a single-use component in most applications — once the bite is set, the ferrule should not be reused on a new tube end. Verify tube OD, wall thickness, and fitting body compatibility before assembly to ensure a leak-free joint.
