Parker PT-00858 Bite-type Tube Union Elbow 12mm Steel

Product Description

The PARKER PT-00858 is a flareless bite-type tube union elbow designed for high-pressure hydraulic and instrumentation tubing systems. This steel union elbow uses a bite-type compression ferrule to grip and seal the tube without requiring any flaring. It connects two tube runs at a 90-degree angle and is rated for a maximum working pressure of 400 bar. Commonly installed by hydraulic technicians, industrial mechanics, and instrumentation specialists, it is suited for demanding fluid power and process control applications where reliable leak-free performance is required.

This fitting is used in hydraulic circuits, fluid power systems, and industrial instrumentation lines where 12 mm OD tubing must be routed at a right angle. The bite-type design is well established in European and international fluid power installations that follow metric tubing standards. It is appropriate for both new construction and service replacement work on machine tools, mobile hydraulics, and process equipment where high operating pressures are present.

Key Features

• Flareless bite-type design eliminates the need for tube flaring during assembly
• Rated for 400 bar maximum working pressure for demanding hydraulic service
• Accepts 12 mm outside diameter tubing
• Steel construction provides strength and durability in fluid power environments
• Union configuration allows inline connection and field disassembly without special tooling

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and instrumentation systems using 12 mm OD metric tubing with flareless bite-type connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with bite-type compression fittings. De-pressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Follow the fitting manufacturer and system OEM assembly procedures for pre-swaging or pre-biting the ferrule onto the tube before final make-up torque is applied. Do not mix metric bite-type fittings with non-metric or flare-style components in the same circuit.
