SYNERINGS®
The Synering® system is an advanced sealing concept designed to meet extreme demands regarding temperature, medium, etc. which cannot be covered by conventional sealing compounds (like elastomers, PUR, fabric materials, etc.)
PTFE is hardly elastic. Therefore, PTFE sealing elements have to be combined with an elastic component, usually an O-ring. Synerings® consist of a PTFE part, made of a specially modified compound, and an energizing spring (standard: stainless steel). So, the outstanding thermal and chemical properties of PTFE can be used to full advantage.
NewDealSeals supplies a wide range of spring-energized seals as an economic alternative to for instance Balseal®, Flexiseal®, Omniseal® and Variseal®.
HOW DOES THE SYNERING® WORK?
The Synering® is compressed radially resp. axially when installed in the seal gland. The resilient spring responds with constant force, pushing out the sealing lips. As system pressure is applied, the seal is additionally energized, increasing the sealing force.
In dynamic applications, the spring expands, compensating for seal wear while continuing to provide load. In conditions that see thermal cycling, the spring continues to energize the seal lips without taking a compression set or becoming too soft or too hard

Back-up Rings
Back-up rings are used for static and dynamic applications in connection with O-rings, to prevent extrusion of the O-ring into the diametrical clearance.
Rotary Seals
Rotary seals are used in applications with oscillating or rotating movements in order to retain liquid lubricants and to prevent the penetration of dirt and water.
Rod Seals
The Rod Seal consists of a single-acting PTFE rod sealing ring and an O-ring. They are combined as a single unit and are appropriate for rods and plungers in hydraulic cylinders.
