Wills Rings
Wills Rings® are metal seals, supplied in two forms, either O or C cross-sections. Controlled-compression type face seals, for static use only, they are designed for use in extreme conditions where the capabilities of polymeric seals are exceeded. Wills Rings® can be supplied in a wide range of metals, which can then be coated or gas-filled to suit their specific application.

Step Seals
The Turcon® Stepseal® K, comes closest in satisfying the ideal demands of a dynamic seal. That is, no leakage under all dynamic conditions and completely leaktight when the system is static. In use for several decades, this seal remains a technically outstanding design. The single-acting sealing element is made of high-grade Turcon® materials with superior sliding and wear resistance properties.A full range of sizes are offered to suit all MIL-G-5514F and Trelleborg Sealing Solutions standards using an O-Ring as the energising element.

Radial Oil Seal
Radial Oil Seals consist of a single lip bonded to a metal support with a garter spring. There are many different variations of the Radial Oil Seal, both with and without an integral dust excluding lip. These dust lips can be positioned either within the seal width or beyond the seal base. A successful Radial Oil Seal runs with a thin film of fluid under the sealing lip. The film acts as a lubricant and allows a meniscus to form on the other side of the sealing lip. Radial Oil Seals can also include hydrodynamic aids, which create positive sealing by returning any oil leaking back into the system. For pressures above the recommended 0.05 MPa (7.3 psi) a metallic support heel can be used.

O-Ring
Simple in shape, the O-Ring is most commonly used in static sealing applications where simple, cost-effective leak tight performance is required. O-Rings can be supplied against all internationally recognised size standards, and can be produced in all aerospace type elastomers. These include Nitriles (NBR), Ethylene Propylene Dieme Monomers (EPDMs), Fluorosilicones (FVMQ), Fluorocarbons (FKM) and Perfluoroelastomers (FFKM), including the almost universally chemically resistant Isolast®. Non-standard sized O-Rings are available on request. In addition, special O-Rings can be supplied with their flashline in a specified position on the seal or inspected to stringent criteria, if required.

mechanical face seals
Mechanical Face Seals are a special form of mechanical seals. They are also known under other designations, such as lifetime seals, floating seals, duo cone seals, toric seals and heavy duty seals. There are two different types of Mechanical Face Seals: Type DO is the most common form that uses an O-Ring as a secondary sealing element. Type DF has an elastomer with a diamond-shaped cross section as a secondary sealing element instead of the O-Ring. To search for available articles, please use the Electronic Catalog.

Hydraulic Scrapers
Scrapers or Wipers are installed in the sealing configurations of hydraulic cylinders to scrape dirt, foreign particles, chips or moisture from the piston rods as they retract into the system. A hydraulic wiper or scraper prevents contamination of the hydraulic medium that could damage wear rings, seals and other components. Scrapers in our E-Catalog (metric) Scrapers in our E-Catalog (inch) Use our CAD Service to download seal profiles direct to your CAD drawings Watch our film: Wiper seal Zurcon® Scraper DA24 Venting Version Trelleborg Sealing Solutions offers a wide range of hydraulic scrapers and wipers in metal, elastomer, Turcon® Polytetrafluoroethylene (PTFE) based material or Zurcon® polyurethane.

diaphragms seals
All diaphragms are custom designed to suit the requirements of an application and can either be manufactured from fabric-reinforced or thin membrane rubber-only material. Higher pressures can be accommodated, by increasing the burst resistance, with synthetic fabric reinforcement. This also gives the advantages of extended product life, reduced deformation and allows the use of thinner sections to improve sensitivity of control. Diaphragms are commonly used in aircraft fuel systems, for example in control and metering valves.

Bonded Seals
The Bonded Seal comprises a metal annulus, square or rectangular in section, to which an elastomeric ring of trapezoidal section is bonded. Developed to replace copper type washers in high-pressure hydraulic and pneumatic threaded connections, the metal ring resists the pressure bursting forces and limits the deformation of the elastomeric element. This prevents over-compression and extrusion.The standard type Bonded Seal is supplemented by a range of self-centering Bonded Seals that eliminate the possibility of leakage, by ensuring it is properly centered during assembly. Available in a wide range of aerospace and defense released materials. Custom designs are also available.
