Parker 8-8-8 Slo-s Male Branch Tee 1/2-14 Nptf Orfs

Product Description

The PARKER 8-8-8 SLO-S is a compression tube male branch tee fitting designed for high-pressure hydraulic and fluid power lines. Constructed from zinc-plated steel, it provides corrosion resistance in demanding service environments. The fitting connects one 1/2-inch outside diameter compression tube port to an O-Ring Face Seal (ORFS) interface and a 1/2-14 NPTF threaded port, creating a branch connection in a single compact body. It is rated to 6000 psi maximum working pressure, making it suitable for high-pressure hydraulic circuits. Hydraulic technicians and fluid power specialists install this fitting when a branch takeoff is required in a tube-run assembly.

This fitting is used in mobile hydraulic equipment, industrial fluid power systems, and heavy-duty machinery where reliable branch connections are needed in high-pressure lines. The ORFS end connection provides a leak-free metal-to-metal seal with a face-seal O-ring, while the NPTF thread ensures a pressure-tight mechanical seal on the branch port. Typical applications include tractor hydraulics, construction equipment, and industrial press circuits where tube-to-port branch tees are required at 1/2-inch tube size.

Key Features

• Rated to 6000 psi maximum working pressure for high-pressure hydraulic service
• Zinc-plated steel construction provides corrosion resistance in industrial and mobile environments
• ORFS end connection delivers a leak-free face-seal interface
• 1/2-14 NPTF thread standard ensures a pressure-tight mechanical thread seal on the branch port
• 1/2-inch tube outside diameter compression fitting for direct tube engagement
• Compact male branch tee body consolidates three connections in one fitting

Compatibility

Designed as a direct-fit replacement for compression tube male branch tee applications requiring 1/2-inch outside diameter tube, ORFS face-seal connections, and 1/2-14 NPTF threaded ports in systems rated up to 6000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the ORFS sealing face and O-ring for nicks or contamination before assembly; a damaged face seal will not hold pressure. Follow the fitting manufacturer torque guidelines for the tube nut and ensure NPTF threads are engaged with appropriate thread sealant per system requirements.
