HiMod® FlatSeal™

Details of gaskets in the HiMod® FlatSeal™ range:


HiMod® FlatSeal™10 – A good all rounder

Suitable for a broad variety of standard applications, this gasket is ideal for use in average temperatures and pressures.


HiMod® FlatSeal™15 – Ideal for steam, oils, fuels and hydrocarbons

This gasket shows exceptionally good resistance to steam and fluids such as oils, fuels and hydrocarbons.


HiMod® FlatSeal™ 17 - The solution for original equipment

HiMod® FlatSeal™ is based on an innovative blend of high-quality aramid fibers, special functional fillers and Nitrile rubber (NBR). The new material combines the characteristics of fiber gaskets with the positive properties of elastomers, thus making it possible to produce a unique performance profile.


HiMod® FlatSeal™20 – Long-term resistance to high pressure

Providing high long-term pressure resistance, this gasket is also blowout resistant and complies with fugitive emissions standards.


HiMod® FlatSeal™ 30 and 31 - The intelligent problem solvers

A combination of expanded graphite and expanded flat metal inlay makes these seals intelligent problem solvers, adapting to any flanges they are fitted to.


HiMod® FlatSeal™36 - Material profile ensures maximum safety

Made of expanded graphite with flat metal inserts, this gasket has the best pressure to temperature ratio of any gasket on the market.


HiMod® FlatSeal™43 and 45 – Superior performance in food applications

Suitable for food contact, the gaskets offer improved performance compared to conventional polytetrafluoroethylene (PTFE) flat gaskets.



Liquid Silicone Rubber (LSR)

Advanced Liquid Silicone Rubber (LSR) technology is seeing exponential growth, particularly into high-tech fields of applications.


Operating in this emergent niche, Trelleborg Sealing Solutions is the world’s leading exponent of precision Liquid Silicone Rubber (LSR) and Two-Component (2C)manufacturing processes and tooling technology driven by Swiss precision thinking. Complex geometries, including multi-components, are produced at our strategically positioned global manufacturing facilities in the same consistent way, with the same processes worldwide.


2C LSR Technology - The Ultimate LSR Process


One of Trelleborg's most outstanding capabilities is the simultaneous injection of LSR in combination with technical plastics, 2C LSR Technology. In what is commonly also referred to as 2K, 2shot, multi-component injection molding, or co-injection, Trelleborg employs highly advanced and sophisticated tool and process engineering to develop the most innovative solutions, combining two, three or more individual materials into one fully bonded, robust component.

Oil Seal Design

Although there are many styles of Oil Seals, they all generally consist of a flexible rubber lip bonded to a rigid metal case. Most also contain a third element – a garter spring – fitted into the rubber lip to provide additional sealing force, both initially and over the life of the seal. The total radial force of the sealing lip is a function of the rubber pre-tension, coupled with the tensile spring force. The sealing lip may be lathe cut or ready molded, and may feature molded-in hydrodynamic aids to assist sealing in demanding applications. The metal case may be exposed or have rubber molded around it for ease of assembly or improved static sealing.

Trelleborg Sealing Solutions offers state-of-the-art Oil Seal design standards based on many years of experience in a wide range of application fields.

Hydraulic Seals 

Hydraulic applications are challenging for Seals. Not only must the hydraulic seals prevent leakage of fluid from the Cylinder, but hydraulic seals must also withstand high pressures, extreme temperatures and transverse forces within the cylinder. In such applications, the function of Hydraulic Seals goes far beyond preventing fluid leakage.

We also offer an e-Learning program on sealing technology:


Hydraulic Cylinder Seals: Performance and Durability

Hydraulic systems are sealed using a combination of specialized seals. Hydraulic Rod seals prevent leakage of fluid from within the cylinder to the outside while hydraulic piston seals prevent fluid from flowing across the cylinder head. This allows pressure build up on one side of the piston, making the Cylinder extend or retract. Wear rings guide the piston and piston rod within the hydraulic cylinder, absorbing transverse forces, preventing metal-to-metal contact. Scrapers or Wipers scrape dirt, foreign particles, chips or moisture from the piston rods as they retract into the cylinder, preventing contamination.

O-Rings Seals Manufacturer

O-Rings are used in a variety of fields: they are either used as sealing elements or as energizing elements for hydraulic slipper seals and wipers. Thus, the O-Ring is basically used in every field of industry including aerospace, automotive or general engineering.


Your Advantages

Today, the O-Ring is the most widely used seal because of its inexpensive production methods and its ease of use. We offer you a range of elastomeric materials for both standard and special applications which allow the O-Ring to seal practically all liquid and gaseous media.

The perfect O-Ring for each purpose


Our O-Rings are both cost-effective and perform highly in almost every environment. No matter if you need metric or inch, standard or custom-made O-Rings – any size of O-Ring seals is available – including giant O-Rings using our Fleximold™ process. Our rubber O-Rings are made of EPDM, FKM, NBR, HNBR, as well as our proprietary FFKM, Isolast®. Special products apart from rubber O-Rings such as O-Rings in PTFE based Turcon® material and Wills Rings® metal O-Rings are also available.
