37° Flared Fittings for Aluminum Tubing
![](/prerenderstable/mvPRE/contents/gfx/imagecache/222/2227k82-1633697317-p9@halfx_637692761356643819.png?ver=imagenotfound)
- For Use With: Air, Coolant, Gasoline, Hydraulic Fluid, Water
- Temperature Range: -60° to 400° F
- Tubing: Use with seamless aluminum
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings are aluminum, which is lightweight with good corrosion resistance. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.

Anodized aluminum resists corrosion and wear better than uncoated aluminum and has a finished appearance.
Black powder-coated aluminum blends in with backgrounds and hides dirt and grime.
Fittings that meet UL 2703 are approved for use in solar rack mounting systems.

Through-hole fittings allow rails to run all the way through.
Add-on through-hole fittings can be added to existing structures without disassembling.
Carbon Fiber Slip-On Framing and Fittings
Stronger than plastic and aluminum, this is the lightest weight framing we offer. It has good resistance to chemicals and salt water. Slip the fittings over rails to construct custom railings, guard rails, storage racks, and shelving. Drill rails and connect fittings with the included hardware.

Heavy Duty Clamp-On Framing and Fittings
Thick construction makes this framing strong and sturdy. This system has a secure clamping mechanism to hold heavy loads—no machining or welding required. Use clamp-on framing and fittings to form temporary partitions, modular conveyors, and workstations. Clamp fittings onto the rail and tighten the included hex head screws.

Flush-Fit Framing and Fittings
Flush connections between rails and fittings give structures a clean finished look. Use this framing for stair rails, work platforms, and workstations. Slide the rail over a fitting and tighten the included set screw—the fitting grips the rail from the inside.
