Parker 12 Bl-s Tube Support 3/4 in Od Orfs 1-3/16-12 Unf

Product Description

The PARKER 12 BL-S is a compression-style tube support fitting designed to reinforce tubing at connection points and prevent deformation under torque or vibration. Manufactured from steel, this tube support is used with O-Ring Face Seal (ORFS) end connections and features a 1-3/16-12 UNF thread size. It is suited for hydraulic and fluid transfer lines where tube integrity at the fitting interface is critical. Weighing 0.2 pounds, it is a small but functionally important component installed by hydraulic technicians and fluid power mechanics working on mobile or industrial equipment.

This tube support is designed for use with tubing that has a 3/4-inch outside diameter. It is a common component in hydraulic plumbing assemblies found in industrial machinery, mobile equipment, and other high-pressure fluid systems. ORFS connections are widely used in these applications because of their leak-free sealing performance. This fitting is sold individually and is appropriate for new installations as well as service and repair work on existing hydraulic lines.

Key Features

• Steel construction for durability in hydraulic and fluid power applications
• O-Ring Face Seal (ORFS) end connection for reliable leak-free sealing
• 1-3/16-12 UNF thread size for precise thread engagement
• Fits 3/4-inch outside diameter tubing
• Compression-style tube support prevents tube deformation under load or torque
• Lightweight at 0.2 pounds for easy handling during assembly

Compatibility

Designed as an OEM-style replacement or new-installation tube support for hydraulic and fluid transfer systems using 3/4-inch OD tubing with ORFS end connections and 1-3/16-12 UNF threading.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic familiar with ORFS fitting assembly procedures. Depressurize and fully drain the hydraulic system before removing or installing any fittings. Follow the fitting manufacturer torque guidelines for ORFS connections and ensure the O-ring is properly seated and free of damage before assembly. Refer to applicable industry standards for hydraulic system plumbing practices.
