Parker 8-8-6 Jbu-s Flareless Bite-type Tube Union Tee

Product Description

The PARKER 8-8-6 JBU-S is a flareless bite-type tube union tee fitting designed to create a rigid, leak-resistant branch connection in hydraulic and instrumentation tubing systems. The fitting accepts a 1/2 inch tube outside diameter and threads into a 3/8 inch NPTF port. The bite-type design uses a ferrule that bites into the tube wall on installation, eliminating the need for flared tube ends. Plumbers, hydraulic technicians, and instrumentation fitters install this fitting in applications where a reliable three-way tube junction is required without welding or brazing.

This union tee is suited for use in industrial fluid systems, hydraulic lines, and instrumentation tubing runs in both commercial and light industrial environments. The flareless design simplifies field assembly in tight spaces where a flaring tool cannot be used. It is commonly installed in process piping, mobile hydraulic equipment, and machine tool hydraulic circuits that require a branch tee at a tube run.

Key Features

• Flareless bite-type ferrule design eliminates the need for tube flaring during assembly
• Union tee configuration allows three-way connection with full tube-to-tube continuity
• 1/2 inch tube outside diameter accommodates standard instrumentation and hydraulic tubing
• 3/8 inch NPTF thread provides a pressure-tight mechanical seal at the port connection
• Compact form factor suited for installation in confined plumbing and hydraulic assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fitting for flareless bite-type tube systems using 1/2 inch OD tubing with a 3/8 inch NPTF threaded port connection.

Installation Notes

Installation should be performed by a qualified hydraulic technician, plumber, or instrumentation fitter familiar with flareless tube fitting assembly procedures. Depressurize and isolate the system completely before disassembling any existing fittings or installing this union tee. Follow the fitting manufacturer's prescribed ferrule presetting procedure to ensure the ferrule seats correctly on the tube OD before final assembly. Refer to applicable codes and system design specifications for pressure ratings and material compatibility before installation.
