Parker 5 Ebu-s Flareless Bite-type Tube Union Elbow

Product Description

The PARKER 5 EBU-S is a flareless bite-type tube union elbow fitting designed to create a leak-resistant 90-degree connection between two tube runs without requiring flared tube ends. The bite-type design uses a compression ferrule that bites into the tube OD as the fitting is tightened, forming a secure mechanical seal. This fitting accepts 5/16 inch tube OD and features 5/16 inch NPTF threads. It is used in hydraulic, pneumatic, fuel, and instrumentation tubing systems where a compact directional change is needed. Installation is typically performed by licensed pipefitters, hydraulic technicians, or mechanical contractors working on fluid power or process lines.

This union elbow is suited for applications in industrial, mobile equipment, and OEM fluid power systems where rigid or semi-rigid tubing must make a directional turn at a connection point. The flareless bite-type configuration is common in close-quarters installations where flaring the tube end is not practical. The NPTF thread type provides a dry-seal mechanical thread engagement that reduces reliance on thread sealants in many applications.

Key Features

• Flareless bite-type design eliminates the need to flare tube ends before assembly
• Union elbow configuration joins two tube segments at a 90-degree angle
• 5/16 inch tube OD compatibility for standard small-bore tubing
• 5/16 inch NPTF dry-seal threads for secure port engagement
• Compact form factor suited for tight installation spaces

Compatibility

Designed as an OEM-style replacement or service fitting for flareless bite-type tube fitting assemblies using 5/16 inch OD tubing with 5/16 inch NPTF threaded ports.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic technician familiar with flareless compression fitting assembly procedures. Depressurize and isolate the fluid system completely before removing or installing any fittings. Follow the fitting manufacturer's prescribed ferrule pre-swage or nut-turn method to achieve proper bite without over-tightening. Refer to applicable fluid system codes and equipment OEM specifications for torque and assembly guidance.
