Parker PT-00159 Flareless Bite-type Tube Ferrule 3/4 in

Product Description

The PARKER PT-00159 is a flareless bite-type tube ferrule designed for use in compression-style tube fittings that require a secure, leak-resistant mechanical seal without flaring the tubing end. The ferrule bites into the outer wall of the tube as the fitting is tightened, creating a metal-to-metal grip. This style of ferrule is commonly used in hydraulic, pneumatic, and instrumentation tubing systems where reliable tube retention is critical. Sold in a package of 5, this ferrule fits tubing with a 3/4 inch outside diameter. Installation is typically performed by licensed plumbers, pipefitters, or instrumentation technicians working on fluid or gas distribution lines.

The PT-00159 is suited for flareless compression fitting assemblies in both industrial and commercial applications. It is used wherever tubing runs require a reusable, bite-type mechanical connection, including HVAC refrigerant piping accessories, hydraulic control lines, and process instrumentation tubing. The 3/4 inch tube OD size covers a common range of medium-bore tubing used in trade and industrial service work. Each package contains 5 ferrules, making it practical to stock for repeat service calls or multi-point installations.

Key Features

• Flareless bite-type design eliminates the need to flare tubing before assembly
• 3/4 inch tube outside diameter sizing for common medium-bore tubing
• Mechanical bite action creates a firm, leak-resistant grip on tube OD
• Packaged in quantities of 5 for efficient stocking and service use
• Compatible with standard flareless compression fitting bodies and nuts

Compatibility

Designed as an OEM-style replacement or service component for flareless bite-type compression fitting assemblies accepting a 3/4 inch tube OD ferrule.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or instrumentation technician. Shut off and depressurize the system completely before disassembling any tube fitting. Follow the fitting manufacturer's recommended pre-set and tightening procedure for flareless bite-type ferrules, as overtightening can deform the ferrule and compromise the seal. Refer to applicable codes such as ASME B31.1 or B31.3 for pressure piping system requirements.
