Swivel Joints

FS6500 Series Swivel Joints

FS65 Series Swivel Joints feature compact forged casings. Their balanced-pressure design distributes pressure evenly through the body of the joints, eliminating axial loading of the sleeve. This allows the swivel joints to rotate with very low torque—even up to their fully rated operating pressure.

The FS65 is available in sizes 1/4 - inch to 1 - inch. The swivel joints have pressure capabilities up to 5,000 PSI for the 1/4-inch and 3/8- inch sizes; 3,500 PSI for the 1/2-inch, 5/8-inch, and 3/4-inch sizes; and 3,000 PSI for the 1-inch size.

FS5900 Series Swivel Joints

The FS5900 Series Swivel Joint is designed for 25 in./Hg vacuum to 5000 psi operating pressure service made possible by advanced design needle bearings and seals. In addition to high pressures, the FS5900 series provides full fluid flow with minimal pressure drop.

The excellent corrosion resistance of the FS5900 series is made possible by the plated steel components.

Both field and laboratory testing have proven the FS5900 Series Swivel Joints can withstand greater side loads than conventional swivel joints. High pressure impulse life has also been improved.

Advantages of using Danfoss Swivel Joints

1. Better System Plumbing:

• Less hose is needed when swivel joints are used, the system is more space efficient (Figure 1).
• Can eliminate the need for tubing configurations to accommodate 90° and other angles.
• Can be directly connected to hose lines frequently eliminating the need for adapters.

2. Prevent Hose Twisting and Kinking:  The swivel action swivel joints prevent hose twisting and kinking.

3. Less Downtime:  The problem of hose twisting and kinking is eliminated and hose line replacement becomes significantly less.

4. Absorb System Shock: Swivel joints are not rigid and therefore capable of absorbing some hose shortening when the system is pressurized.

5. Cost Savings: Less hose, fewer adapters and tubing configurations and less downtime add up to saving money when swivel joints are used.
