Parker PT-00692 Flareless Bite-type Tube Nut 6mm

Product Description

The PARKER PT-00692 is a flareless bite-type tube nut designed for use in hydraulic and instrumentation tube connections that do not require flared tube ends. The nut works in conjunction with a ferrule or sleeve to grip the tube mechanically as it is tightened, creating a leak-resistant seal. It accepts tubing with a 6 mm outside diameter. This type of fitting is commonly installed by licensed plumbers, HVAC technicians, and instrumentation mechanics working on refrigerant, pneumatic, or hydraulic lines.

Flareless bite-type fittings are widely used in residential and commercial HVAC systems, refrigeration equipment, industrial pneumatics, and hydraulic control circuits. They are suited for installations where tube flaring tools are impractical or where a compact, reusable connection is needed. Each nut is sold in packages of 5 units, making them convenient for service techs stocking a van or completing multi-connection jobs.

Key Features

• Flareless design eliminates the need for a tube flaring tool at the connection point
• Bite-type grip mechanism creates a secure, leak-resistant seal on the tube OD
• 6 mm tube outside diameter fitment
• Packaged in quantities of 5 per package for efficient job-site use

Compatibility

Designed as an OEM-style replacement or service nut for flareless bite-type tube fitting assemblies accepting 6 mm outside diameter tubing.

Installation Notes

Installation is typically performed by a licensed HVAC technician, plumber, or instrumentation mechanic. Depressurize and isolate the line completely before disassembling any tube fitting. Ensure the tube end is cut square and deburred before inserting into the fitting body. Follow the fitting manufacturer's prescribed number of turns past finger-tight to achieve proper ferrule bite without over-tightening.
