Parker 6-8 Clo-s Male Elbow 3/8 in Tube Orfs X Nptf 6000 Psi

Product Description

The PARKER 6-8 CLO-S is a compression tube male elbow fitting designed for high-pressure hydraulic and fluid system plumbing. It connects a 3/8 inch outside diameter compression tube to a 1/2-14 NPTF threaded port using an O-Ring Face Seal (ORFS) interface on the tube side. Constructed from zinc-plated steel, it delivers a rated maximum working pressure of 6000 psi, making it suitable for demanding hydraulic line routing where a 90-degree directional change is required. Plumbers and hydraulic system technicians install this fitting when routing hard or soft tubing to manifolds, pumps, valves, or cylinder ports with NPT-style threaded entries.

This fitting is used in industrial and mobile hydraulic systems, fluid power circuits, and high-pressure plumbing assemblies that require a reliable leak-resistant elbow connection. The ORFS interface provides a positive metal-to-metal seat backed by an O-ring seal, which minimizes the risk of leakage under pressure cycling and vibration. Typical installation scenarios include equipment hydraulic lines, machine tool plumbing, and off-highway vehicle fluid circuits where hard-line tube routing meets threaded port connections.

Key Features

• 90-degree male elbow configuration routes tubing at a right angle to threaded ports
• ORFS x NPTF end connections combine O-Ring Face Seal tube end with a tapered pipe thread port connection
• 6000 psi maximum working pressure rating supports high-demand hydraulic applications
• 3/8 inch tube outside diameter compression end for standard hydraulic tubing
• Zinc-plated steel construction provides corrosion resistance in typical shop and field environments
• 1/2-14 NPTF thread size conforms to National Pipe Taper Fuel standard for pressure-tight thread engagement

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power systems using 3/8 inch OD compression tube with 1/2-14 NPTF threaded port connections and ORFS interface fittings.

Installation Notes

Installation should be performed by a qualified hydraulic technician or plumber familiar with high-pressure fluid system assembly. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. Inspect the O-ring and sealing faces for damage before assembly, and ensure the NPTF threads engage cleanly without cross-threading. Follow applicable fluid power system standards and equipment manufacturer guidelines for assembly procedures.
