Dichtomatik is a global service provider and distributor of standard and customized sealing technologies Dichtomatik has grown to be a major supplier in the sealing and custom molded rubber products marketplace.
Dichtomatik provides a broad range of seal sizes, type, material and styles.
Dichtomatik has a wide range of inch dimensional seals and on of the largest inventories of metric shaft seals Offered products range from AP Seals, Axial Face Seals, Bonded Seals, Custom Molded Parts, C.V. Joint Boots, End Caps, Fluid Power, O-Rings, Oil Seals, Polyurethane Seals, Trailer Kits, V-Rings, Valve Stem Seals and Wiper Seals.
Dichtomatik products include radial shaft seals, o-rings, hydraulic seals, fastener seals, molded rubber, and extruded/spliced cord. Dichtomatik was formed after the acquisition of American Seal, Transcom (TCM), Nu Seal, and International Seal by Freudenberg in 2002. Dichtomatik Americas was created as a result of FST purchasing Transcom and American Seal.
Dichtomatik oil seals or shaft seals cover a variety of applications including axles, engines, trailers and high-pressure environments. They are used to seal around a rotating shaft and provide protection from dirt intrusion while retaining an oil-based lubricant within the shaft.
Two characteristics make up an o-ring, the shape and the material of construction. The shape is a circular torus or doughnut-shaped ring. Only two of the three primary dimensions—the inner diameter (ID), the outer diameter (OD), and the cross-section (CS)—are required to specify the size. Dichtomatik o-rings are available in almost any size and in a wide range of materials.
O-Ring Materials: Nitrile Rubber (NBR), Hydrogenated Nitrile Rubber (HNBR), Silicone, Viton (FKM), Teflon (PTFE), Neoprene, Kalrez, Polyurethane, Aflas, Teflon Encapsulated, Viton and Silicone, Ethylene Propylene Diene Monomer (EPDM).
O-Ring Seals: An o-ring seal has two basic components: the o-ring and the enclosed space that both compresses and contains the o-ring. The compression of the o-ring provides part of the sealing function. Additional sealing function is realized when the o-ring is activated by the pressure of the gas or liquid that the o-ring serves to contain.
Fastener seals consist of an inner rubber component used in conjunction with an outer metal washer that supports the sealing function of the fastener such as a screw or bolt. The rubber and metal combination creates an ideal fit to eliminate clearance gaps between the housing components and protects against leaks in static applications. Fastener seals are intended to take the place of an o-ring in certain assemblies. Dichtomatic types include Bonded Seals, DC Fastener Seals, and DCCL Thread seals.
Fluid power seals are primarily used in hydraulic cylinder applications where high pressure and fluid maintenance is vital for optimum equipment performance. Common types include:
