Parker 16 Klo-s Compression Tube Union 1 in Orfs 6000 Psi

Product Description

The PARKER 16 KLO-S is a compression tube union fitting designed to create a secure, leak-resistant connection between two tube ends in high-pressure hydraulic and fluid power lines. Built from steel with O-Ring Face Seal (ORFS) end connections and UNF threading, this union supports a maximum working pressure of 6000 psi. It accepts a 1 inch tube outside diameter on both ends. Licensed HVAC technicians, hydraulic system mechanics, and fluid power specialists install this fitting in demanding industrial and mobile equipment applications where vibration resistance and reliable sealing are required.

This fitting is suited for use in high-pressure hydraulic circuits, fluid conveyance lines, and related systems where ORFS connections are specified. The O-Ring Face Seal design provides a positive metal-to-metal contact surface combined with an elastomeric seal, making it effective in applications exposed to vibration, pressure spikes, or fluid contamination risks. It is commonly used in both stationary industrial equipment and mobile machinery where system integrity at elevated pressures is critical.

Key Features

• Maximum working pressure of 6000 psi for high-pressure hydraulic service
• O-Ring Face Seal (ORFS) end connections for leak-resistant, vibration-tolerant sealing
• Steel construction for durability in demanding fluid power environments
• 1 inch tube outside diameter on both union ends
• UNF thread standard for broad compatibility with ORFS hydraulic components

Compatibility

Designed as an OEM-style replacement or new-installation union fitting for hydraulic and fluid power systems specifying 1 inch OD ORFS tube connections at up to 6000 psi working pressure.

Installation Notes

Installation should be performed by a qualified hydraulic or fluid power technician. Depressurize and fully isolate the hydraulic circuit before removing or installing any fitting. Inspect the O-ring sealing surface for nicks or contamination before assembly, and ensure the O-ring is properly seated and lubricated prior to making up the connection. Torque fittings in accordance with the fitting manufacturer's published torque specifications for the applicable tube size and thread standard.
