Parker PT-00450 Flareless Bite-type Progressive Ring 6mm

Product Description

The PARKER PT-00450 is a flareless bite-type progressive ring designed for use in high-pressure tube fittings. It serves as the compression element in Parker flareless fitting assemblies, biting into the outer diameter of the tube as the fitting is tightened to create a leak-resistant mechanical seal. Manufactured from steel, this ring is rated for a maximum working pressure of 500 bar and is engineered for 6 mm tube outer diameter. Its overall length is 9.5 mm. Licensed technicians and pipefitters working with hydraulic or instrumentation tubing systems are the primary installers of this component.

This progressive ring is suited for industrial hydraulic systems, fluid power circuits, and instrumentation tubing applications where flareless connections are specified. The bite-type design progressively deforms around the tube wall during installation, eliminating the need for tube flaring. This makes it a practical choice for field assembly and repair work where flaring tools are not available or the system design calls for a flareless standard. It is sold in packages of 10 units, making it suitable for service kits and bench stock replenishment.

Compatibility

Designed as an OEM-style component for Parker flareless bite-type fitting assemblies requiring a progressive ring for 6 mm tube outer diameter connections.

Installation Notes

Installation of flareless bite-type fittings is typically performed by licensed pipefitters or hydraulic system technicians. Depressurize and isolate the hydraulic or fluid circuit completely before disassembly or fitting installation. Follow the applicable fitting manufacturer torque procedure for pre-swaging and final tightening — do not substitute generic torque values. Verify tube material and wall thickness compatibility with the fitting and pressure rating before completing the installation.
