Also known as rotary fittings, the S Series swivel fittings product line serves as a perfect complement to the Quick Coupling Division’s PS Series swivel line, bringing a host of advanced features to enhance hydraulic system functionality. At its core is a pressure-balanced, compact forged body design that sets it apart in performance and reliability.

A key advantage of the S Series Swivel lies in its pressure-balanced construction. Unlike conventional fittings, it does not experience a significant increase in torque as pressure rises, ensuring smooth operation even under varying pressure conditions. This characteristic is particularly valuable in dynamic hydraulic systems where pressure fluctuations are common, as it maintains consistent performance and ease of use.
The housing body of the S Series Swivel is forged to deliver superior performance and durability, making it well-suited for tough applications. This robust construction enables it to withstand the rigors of heavy-duty operations, from industrial machinery to mobile hydraulic systems, ensuring long-term reliability and minimizing maintenance needs.
Beyond its structural strengths, the S Series Swivel Fittings excel at solving common hydraulic challenges. They effectively eliminate hose twist, torque, and stress caused by the movement of hydraulic components—provided that side load to the swivel is minimized. This not only extends the lifespan of hoses and related components but also enhances overall system safety and efficiency.
In summary, the S Series Swivel Fittings combine innovative pressure-balanced design, durable forged construction, and practical problem-solving capabilities, making them an essential addition to any hydraulic system seeking optimized performance and longevity.
