Parker 2 Jbu-s Flareless Bite-type Tube Union Tee Steel

Product Description

The PARKER 2 JBU-S is a flareless bite-type tube union tee designed for high-pressure hydraulic and instrumentation tubing systems. It creates a three-way branch connection without flaring the tube end — the ferrule bites into the tube OD on assembly to form a leak-resistant seal. Built from steel, it handles working pressures up to 5,000 psi. The 24-degree flared angle and NPTF thread form a dry-seal connection that resists leakage under pressure and vibration. Hydraulic technicians and instrumentation fitters install this fitting where a tee branch is needed in a flareless tubing run.

This fitting is suited for industrial hydraulic lines, fluid power systems, and instrumentation tubing applications where flareless compression-style connections are specified. The 1/8 inch tube OD and 1/8 inch NPTF thread size make it appropriate for small-bore tubing runs common in control and sensing circuits. It is used in both original equipment assembly and field repair of steel tubing systems operating at elevated pressures.

Key Features

• Flareless bite-type design — no tube flaring required prior to assembly
• Maximum working pressure of 5,000 psi
• 24-degree flared angle with NPTF dry-seal thread form
• Steel construction for durability in high-pressure environments
• 1/8 inch tube OD and 1/8 inch NPTF thread size for small-bore applications
• Union tee configuration enables three-way branch connections in a single fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for flareless bite-type steel tubing systems using 1/8 inch OD tubing with 1/8 inch NPTF threaded ports.

Installation Notes

Installation is performed by qualified hydraulic or instrumentation technicians. Depressurize and isolate the tubing circuit completely before disassembling any fitting. NPTF threads are designed to seal without thread sealant, but follow the system designer or equipment manufacturer guidelines regarding sealant use. Tighten the fitting nut to the recommended turns-past-finger-tight specification for the tube size per the fitting manufacturer's assembly instructions — do not overtighten, as this can damage the ferrule bite.
