NewDealSeals has been advising companies on the use of PTFE, drawing on the extensive knowledge gained from different industries. In spite of its remarkable properties, virgin PTFE (unmixed PTFE) has limited use for applications where high mechanical loading is required.
Furthermore PTFE is not elastic as rubber compounds. For this reason, PTFE seals are provided with a slight amount of tension in relation to the installation diameter. Reliable contact force is guaranteed by an elastomer-expander shaped as an O-ring or rectangular ring or a stainless spring. On this page the most common PTFE Seals are briefly described.
Spring Energized Seals
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.Spring Energized Seals
The Piston Seal consists of a single-acting PTFE piston sealing ring and an O-ring. They are combined as a single unit and are appropriate for single- acting pistons in hydraulic cylinders.Piston Seals
Wiper Seals | Scraper Seals
Wiper seals function to prevent dust, dirt, grains of sand and metal dwarf from penetrating into axially moving rods and plungers.Wiper Seals | Scraper 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.Rod Seals
Guide Rings | Wear Rings
The guide ring or wear ring guides a hydraulic cylinder piston and rod and absorbs lateral forces. Metal to metal contact between the moving parts of the cylinder.Guide Rings | Wear Rings
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.Rotary Seals
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.Back-up Rings
