Introduction
Introduction
The S Series Swivel product line complements the Quick
Coupling Division’s PS Series swivel line by offering a pressure
balanced, compact forged body design. As a result of the
pressure balanced design, the S Series Swivel does not
experience a significant increase in torque as pressure rises.
The housing body is forged to provide superior performance
and durability in tough applications. This product is great
for eliminating hose twist, torque and stress caused by the
movement of the hydraulic components where side load to the
swivel can be minimized.
Features
• 3000
psi working pressure rating for all sizes.
•
Variety of seal options.
•
Torque value does not significantly increase with pressure.
•
Dust seals protect the swivel from damaging environmental
contaminants.
•
Field service kits are available for quick and reliable repairs.
• 360
° swivel eliminates long radius bends, hose twist and
stress that can cause premature hose failure.
•
One piece forged housing eliminates a brazed 90°
adapter connection.
•
Case hardened for enhanced service life.
•
Compact design to fit into tight areas.
