Parker 4 V5BU-S Bite-type Tube Elbow 1/4 in 5000 Psi Steel

Product Description

The PARKER 4 V5BU-S is a flareless bite-type tube fitting designed as a 45-degree straight thread elbow for high-pressure hydraulic and fluid power lines. It accepts a 1/4-inch tube OD and connects via a 7/16-20 NPTF straight thread. The bite-type design eliminates the need for pre-flaring the tube end, allowing the ferrule to cut into and grip the tube wall directly during assembly. Rated to 5,000 psi maximum working pressure, this fitting is suited for demanding fluid power circuits where a secure, leak-resistant connection is required. Constructed from steel for durability in industrial and mobile hydraulic applications.

This fitting is used in hydraulic systems, fluid power circuits, and industrial plumbing installations where a 45-degree change in tube routing is needed. It is commonly installed in OEM equipment, mobile machinery, and plant hydraulic lines where tubing must transition at an angle to a port or manifold. The 7/16-20 NPTF thread provides a pressure-tight mechanical seal at the port end. Both OEM assemblers and field service technicians install this type of fitting during system builds and repair work.

Key Features

• Flareless bite-type design grips tube mechanically without pre-flaring
• 45-degree elbow configuration for angled tube routing
• 7/16-20 NPTF straight thread for a pressure-tight port connection
• Rated to 5,000 psi maximum working pressure
• 24-degree flared angle geometry for proper ferrule seating
• Steel construction for strength in high-pressure hydraulic service

Compatibility

Designed as an OEM-style bite-type tube fitting for hydraulic and fluid power systems using 1/4-inch OD tubing and 7/16-20 NPTF ported components.

Installation Notes

Installation is typically performed by hydraulic system technicians or pipefitters familiar with bite-type fitting assembly procedures. Depressurize and isolate the hydraulic circuit completely before disassembling any fittings or tubing. Use the proper tube cutter to produce a clean, square cut on the tube end, and ensure the tube is fully seated in the fitting body before tightening the nut to achieve proper ferrule bite. Follow the fitting manufacturer's published assembly instructions for turn-past-finger-tight specifications, as overtightening can damage the ferrule or tube wall.
