Static Seals
Static Seals
Static seals from Freudenberg Sealing Technologies are among the elementary components in sealing systems. They are available in different designs, such as o-ring, back ring, flange seal or round cords, as well as made from different materials, including NBR, FKM, EPDM and Simriz, the high performance FFKM material. Static seals are available as standard solutions or custom-manufactured for the application in question.

O-Rings
The O-rings of Freudenberg Sealing Technologies are used for the static sealing of idling machine parts against liquids and gases. The versatile applications include water fittings, air conditioners, vehicle engines or dentist drills. In addition, the classic O-ring seal is also available in special shapes, making it suitable as a dynamic sealing element, for example as piston or rod seals in hydraulics. O-rings are manufactured from a wide variety of materials for all requirements.
X-Rings
In regard to handling and application, Dichtomatik X-rings are similar to O-rings, but have a higher stability due to their X structure. They are double-acting four-lip seals with a practically square cross-section profile. The X-rings achieve their sealing effect when built and pressed into an axial or radial installation space. During operation, the media pressure reinforces the sealing function.
Cords
The special profiles of Freudenberg Sealing Technologies are used to seal large points requiring sealing that cannot be sealed using moulded seals or O-rings, for example, tunnelling machines, ship engines or loading hatches. Upon request, we can develop and produce special profiles or profiles for static applications according to custom designs at very affordable tool costs.
Back-Up Rings
The back-up rings of Freudenberg Sealing Technologies supplement and back up the O-ring. They act as a supporting element to prevent gap extrusion in radially sealing ISC O-rings. By expanding the use of O-rings to various shapes, back seals protect O-rings against damage.
Flange Seals
The flange seals of Freudenberg Sealing Technologies are static compact seals for high-maintenance hydraulic applications. Thanks to the optimised design of the sealing edges (distribution of tension), the flange seals have a firm seat in the installation space.
USIT-Rings Fastener Seals
USIT rings are used for industrial applications in which high seal tightness is required, high pressure predominates and a secure sealing effect must be guaranteed, for example, in the processing, food or pharmaceutical industries. The USIT rings of Freudenberg Sealing Technologies are metallic flat seals with an internally or externally vulcanised, trapezoidal, rubber-elastic sealing bead for the static sealing of screw and flange connections. The sealing bead guarantees a safe, self-reinforcing sealing effect.
Clamp Seals
Clamp seals from Freudenberg Sealing Technologies guarantee a fast and especially secure pipe connection in continually operated equipment. x000D They are nonetheless easy to separate and stand out for their especially easy installation. The dimensions are standardized according to DIN 32676, and, as a result, the seals are standardized and thus especially economical and available from stock. x000D As materials, Freudenberg Sealing Technologies recommends 70 EPDM 291, 70 VMQ 117055, Fluoroprene XP 41 and 70 EPDM 253815 (white).
