Parker 4 Clo-s Male Elbow Fitting 1/4 in Od Orfs Nptf 6000 Psi

Product Description

The PARKER 4 CLO-S is a compression tube male elbow fitting designed for high-pressure hydraulic and fluid system connections. It provides a 90-degree directional change in a tube line, connecting a 1/4-inch outside diameter tube to a 1/8-27 NPTF threaded port using an O-Ring Face Seal (ORFS) interface. Constructed from zinc-plated steel, the fitting is rated to a maximum working pressure of 6000 psi. This type of fitting is installed by hydraulic system technicians, maintenance mechanics, and plumbing professionals working on industrial fluid lines, mobile equipment, and related systems requiring leak-free directional transitions.

This fitting is suited for use in hydraulic, pneumatic, and fluid transfer systems where a tube line must change direction and terminate at an NPTF-threaded port. The ORFS interface provides a metal-to-metal seat sealed by an O-ring, reducing the risk of leakage under pressure cycling. Typical installations include industrial machinery, mobile hydraulic circuits, and fluid power assemblies. The zinc-plated steel construction offers corrosion resistance appropriate for general indoor and sheltered outdoor service environments.

Key Features

• Compression-style tube end accepts 1/4-inch outside diameter tubing
• 1/8-27 NPTF male thread for secure, pressure-tight port connections
• O-Ring Face Seal (ORFS) design minimizes leakage under pressure cycling
• Maximum working pressure of 6000 psi for demanding hydraulic applications
• Zinc-plated steel construction provides corrosion resistance in general service conditions
• Male elbow configuration allows 90-degree directional routing of tube lines

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power systems requiring a 1/4-inch OD compression tube to 1/8-27 NPTF male elbow connection with an O-Ring Face Seal interface.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and isolate the fluid system completely before removing or installing any fittings. Inspect the O-ring and seating surfaces for damage before assembly, and ensure the NPTF threads are clean and free of debris. Follow applicable fluid power standards and the fitting manufacturer guidelines for proper assembly torque and tube insertion depth.
