Parker PT-00693 Flareless Bite-type Tube Nut 10mm

Product Description

The PARKER PT-00693 is a flareless bite-type tube nut designed for use in compression-style tube fittings where a flared end is not required. The bite-type design uses a ferrule to grip and seal the tube mechanically, eliminating the need for flaring tools. This nut is sized for 10 mm tube outside diameter and is a standard component in hydraulic, pneumatic, and fluid-conveyance systems. Installation is typically performed by licensed HVAC technicians, plumbers, or hydraulic system specialists working on metal tubing runs in equipment or panel assemblies.

Flareless bite-type tube nuts are commonly used in residential and commercial HVAC systems, refrigeration equipment, industrial fluid lines, and hydraulic control circuits. They pair with corresponding ferrules and fitting bodies to form a complete compression joint. This nut is suited for applications where tube flaring is impractical or where system design calls for a bite-type connection standard.

Installation Notes

Installation should be performed by a qualified technician familiar with compression tube fittings and applicable fluid system codes. Shut off and depressurize the system completely before disassembling any tube fittings. Use appropriate tube-cutting and deburring tools to prepare the tube end before assembly. Do not overtighten; follow the fitting body manufacturer's turn-past-finger-tight specification for bite-type ferrule engagement.
