Spring-Energized Seals: SYNERINGS® – At NewDealSeals
In the realm of sealing solutions, there’s a revolutionary concept that stands tall when faced with extreme demands like high temperatures, aggressive mediums, and challenging environments. Say hello to SYNERINGS® – an advanced sealing system that redefines what’s possible in the world of sealing technology. It’s the ultimate solution for conditions where conventional sealing compounds, such as elastomers, PUR, and fabric materials, fall short.
At its core, SYNERINGS® leverages the remarkable properties of PTFE (Polytetrafluoroethylene), a material renowned for its exceptional thermal and chemical resistance. However, PTFE’s inherent lack of elasticity posed a challenge, until the inception of SYNERINGS®. This innovative system ingeniously combines a specially modified PTFE component with an energizing spring, typically crafted from stainless steel. The result? An unbeatable sealing solution that maximizes the extraordinary qualities of PTFE to their full potential.

How SYNERINGS® Works:
- SYNERINGS® is precision-crafted from a unique PTFE compound, tailor-made to excel in the most demanding conditions.
- An energizing spring, often constructed from stainless steel, provides the necessary resilience to achieve a reliable and highly effective seal.
- Upon installation in the seal gland, SYNERINGS® undergoes radial or axial compression. The resilient spring responds with a constant force, extending the sealing lips. As system pressure comes into play, the seal gains additional energization, bolstering the sealing force.
In dynamic applications, the spring expands to compensate for seal wear while maintaining the essential load. Even in scenarios marked by thermal cycling, the spring remains steadfast in energizing the seal lips, all without suffering a compression set or becoming excessively soft or hard.
NewDealSeals proudly offers a wide array of spring-energized seals, including the groundbreaking SYNERINGS®, providing an economical yet high-performance alternative to established brands like Balseal®, Flexiseal®, Omniseal®, and Variseal®.
