Parker PT-00817 Bite-type Tube Union Tee 12mm

Product Description

The PARKER PT-00817 is a flareless bite-type tube union tee fitting designed for metric tube connections with a 12 mm outside diameter. Bite-type fittings use a ferrule that bites into the tube wall during assembly, creating a leak-resistant mechanical seal without flaring the tubing end. This union tee configuration connects three tube runs in a single body, making it well suited for branching hydraulic, pneumatic, or fluid-control lines. Licensed technicians and industrial pipefitters working with metric tubing specify this style of fitting where flaring tools are impractical or where system pressures and vibration demand a secure, permanent-style bite connection.

This fitting is used in metric tube plumbing applications across hydraulic systems, pneumatic control circuits, refrigeration interconnects, and instrumentation lines. Its union tee format allows a main tube run to be tapped at a branch point without cutting into an existing assembly. It is appropriate for both light industrial and OEM applications where 12 mm OD metric tubing is the specified line size. Installation is typically performed by hydraulic or pneumatic system technicians, HVAC refrigeration mechanics, or instrumentation specialists familiar with bite-type ferrule fittings.

Key Features

• Flareless bite-type design eliminates the need for tube flaring before assembly
• Union tee body connects three tube ends in one compact fitting
• 12 mm outside diameter tube size matches standard metric tubing
• Ferrule-based seal provides resistance to vibration-induced loosening
• Compact form factor suits tight plumbing spaces in instrumentation and control panels

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 12 mm OD metric tubing with flareless bite-type connections.

Installation Notes

Shut down system pressure and depressurize all lines before disassembling or installing any tube fittings. Bite-type ferrule fittings require careful tube squaring and proper insertion depth before tightening — follow the fitting manufacturer's assembly procedure for ferrule pre-setting. Ensure tubing is free of burrs, debris, and contamination prior to assembly. Applicable plumbing and fluid-system codes should be consulted for the specific system type and jurisdiction.
