Parker PT-00667 Bite-type Tube Union Reducer 12x8mm

Product Description

The PARKER PT-00667 is a flareless bite-type tube union reducer designed to connect two different tube outside diameters in a single inline fitting. It transitions from a 12 mm OD tube to an 8 mm OD tube without the need for flared tube ends. The bite-type design uses a ferrule that deforms into the tube wall on assembly, creating a secure, leak-resistant mechanical grip. This fitting is well suited for hydraulic, pneumatic, and instrumentation tubing systems where size transitions are required. Installation is typically performed by licensed plumbers, pipefitters, or industrial maintenance technicians working with metric tube systems.

This union reducer is used in applications requiring a direct inline reduction between metric tube sizes. Common install scenarios include hydraulic control panels, pneumatic distribution lines, and fluid power systems in both commercial and industrial settings. The flareless bite-type construction eliminates the flaring step, simplifying assembly in the field or on a bench. Each package contains 2 fittings.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or fluid power technician familiar with flareless bite-type fittings. Depressurize and isolate the system completely before disassembling any existing fittings or tubing. Follow the fitting manufacturer assembly procedure for ferrule pre-swaging to ensure a proper bite and leak-free joint. Refer to applicable system codes and the fitting manufacturer specifications for tube material compatibility and pressure ratings before installation.
