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.
How to Order
When ordering a swivel joint, follow these steps:
1. State the base part number, casing and sleeve port size, as shown.
2. Add the suffix code which indicates the seal required, as shown in the seal chart at right.
Torque vs. Pressure
Testing to determine the torque required to rotate an FS5900 Series Swivel Joint was conducted on actual production assemblies.
Pressure Drop vs Flow
Testing for pressure drop at various flow rates was conducted with MIL-H-5606 hydraulic oil at temperatures (+70°F to +80°F).
