Gaskets O-Rings Gaskets

Gaskets O-Rings Gaskets THOMAPLAST ® -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) 76 THOMAPLAST ® IV - 2015

Gaskets - EPDM O-Rings EPDM O-Rings O-Rings THOMAPLAST ® -High-Performance EPDM O-Rings - imperial ​ THOMAPLAST ® -High-Performance EPDM O-Rings Application area • Very well suited for use in: Hot water and water steam (constant +180 °C, short-term +210 °C) Glycoles and brake fluids (on glycol base) Acids (hydrochloric and nitric acid) Bases (sodium hydroxide, potassium hydroxide) Ozone (+40 °C, 200 pphm) and oxygen CIP /SIP media for continuous plants in the food, beverage and pharmaceutical industries (see EPDM diagram and fat diagram) CIP (Cleaning in Place) = diluted acids or bases combined with cleaning additives SIP (Sterilization in Place) = disinfectants, steam, oxidizing media (e.g. peracetic acid) and / or polar organic solvents (e.g. acetic acid) • Well suited for use in animal fats at low temperatures • Should not be used in mineral fats, oils and waxes, fuels • Recommended lubricant for installation: Silicone grease (e.g. Paraliq GTE 703 with NSF H1 approval) (see fat diagram) • Explanation: This EPDM O-Ring (at low temperatures) is very well suited even at high fat content. Once the curve in the diagram is achieved, another suitable material type (FKM, VMQ or HNBR) should be chosen for the respective application.
