Midland Industries SS6400-16-12 Straight Adapter Jic Orb

Product Description

The MIDLAND INDUSTRIES SS6400-16-12 is a straight hydraulic adapter machined from 316 stainless steel, designed to connect a 1-inch Male JIC fitting to a 3/4-inch Male O-Ring Boss port. The JIC end uses a 1-5/16-12 thread and the ORB end uses a 1-1/16-12 thread. Overall length is 2.039 inches and the adapter weighs 0.425 pounds. It is rated for a maximum operating pressure of 3500 psi and can withstand operating temperatures up to 1000 degrees F. Licensed plumbers, pipefitters, and hydraulic system technicians install this fitting in fluid power and process piping applications where dissimilar fitting standards must be joined without leakage.

This adapter is well-suited for industrial hydraulic systems, fluid transfer lines, and high-pressure process plumbing that require corrosion-resistant fittings. The 316 stainless steel construction makes it appropriate for marine environments, chemical processing, and food-grade applications where carbon steel or brass fittings are not acceptable. It is part of the SS6400 Series, covering MJIC to Male O-Ring Boss configurations.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh and marine environments
• Rated to 3500 psi maximum operating pressure for demanding hydraulic service
• Operates at temperatures up to 1000 degrees F
• Straight adapter profile simplifies inline connections between JIC and O-Ring Boss porting
• 1-5/16-12 Male JIC x 1-1/16-12 Male O-Ring Boss thread combination covers common hydraulic line sizes
• Compact 2.039-inch length minimizes envelope space in tight plumbing runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 1-inch Male JIC and 3/4-inch Male O-Ring Boss connections conforming to standard JIC and SAE O-Ring Boss thread specifications.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic technician following applicable system pressure and fluid compatibility requirements. De-pressurize and drain the hydraulic circuit fully before removing or installing any fittings. Inspect O-ring seating surfaces for nicks or burrs prior to assembly and use a fresh, compatible O-ring to ensure a leak-free seal on the ORB end. Consult system manufacturer torque guidelines and applicable codes for final tightening procedure.
