General Information O-Rings

These O-Ring materials are specially developed for use in the food processing, pharmaceutical, petrochemical and chemical industries, as well as in technological processes

Design: O-Rings are vulcanised in moulds

Method of operation: O-Rings are double-acting sealing elements. The initial squeeze acting in a radial or axial direction due to the installation gives the O-Ring its initial sealing capability. These forces are superimposed by the system pressure to create the total sealing force which increases with increasing system pressure. Under pressure, the O-Ring behaves in a similar way to a fluid with high surface tension. The pressure is transmitted uniformly to all directions (see Figure Sealing forces).

Compared with other sealing elements, the O-Ring has a wide range of advantages: Inexpensive, allows low cost solutions; simple, one-piece groove design reduces hardware and design costs; compact design allows smaller hardware; easy, foolproof installation reduces risk; applicable to a wide range of sealing problems, static, dynamic, single or double acting; wide compound choice for compatibility with most fluids

Most common applications: Sealing of static machine parts against liquid or gaseous media; as a radial static seal, e.g. for bushings, covers, pipes, cylinders; as an axial static seal, e.g. for flanges, plates, caps; as a dynamic sealing element at axial, rotating and oscillating movements

Branch-specific sealing solutions: Approvals and conformities in the food processing industry: ADI free, FDA, 3-A; Sanitary Standards; pharmaceutical industry: ADI free, USP Class VI

Petrochemical industry: ex. decompression

Chemistry: permeation density and chemical stability

Dimensions: Inched ARP 001 - 932; Metric ID 3 - 193 mm; Cord thickness 1 - 8 mm

Manufacturing: According to the latest standards, with an optimal tool park, for quick and flexible handling, the traceability of materials is guaranteed, all parts go through a quality check before packaging

Usual application areas for elastomers regarding temperature and polarity of the used media

Approvals and certificates in the food, pharmaceutical and drinking water industries (see list of approvals)

Usual cleaning media for continuous plants in the food and pharmaceutical industries (see list of cleaning products)

General Information FFKM

Very well suited for use in:

static and dynamic applications, applications involving constant temperature changes, all fats, mineral oils and waxes, fuels, water and water steam, concentrated acids (e.g. nitric acid 60 %), amines (e.g. ethylenediamine), organic acids (e.g. acetic acid), ketones (e.g. methyl ethyl ketone), bases (e.g. caustic soda, potassium hydroxide), organic solvents (e.g. methanol), aromatic and chlorinated hydrocarbons

Extremely resistant to a variety of chemicals from different reactive, functional groups (comparable to PTFE)

FFKM offers the highest degree of fluorination among elastomers

High bond energy between carbon and fluorine atoms

No cold flow compared to PTFE

Highest temperature and media resistance combined with rubber-elastic properties

FFKM is suitable for use in polar and non-polar media, even in higher concentrations and at higher temperatures

Sealing solution for applications related to safety

Highly pure, proven material
