Special Elastomeric Seals

Since 1977

Manufacturing Special Elastomeric Seals

In addition to traditional piston and rod seals, scrapers, anti-extrusion rings, and common O-rings, LIMA is capable of manufacturing a wide range of custom-designed special seals made from elastomeric materials, tailored to the specific needs of the customer.

Thanks to the advanced technologies at our disposal, the extensive experience of our operators, and our collaboration with industry-leading companies, LIMA can provide seals with complex geometries that meet even the most stringent tolerances.

Special profile seals are used as auxiliary sealing elements for a wide variety of components: compressors, heat exchangers, flanges, housings, baskets, pipes, fittings, slides, panels, rollers, plugs, nozzles, mechanical parts of machinery, drain systems, spacers, and sensors.

Elastomeric Materials

The variety of profiles that can be manufactured is considerable: for proper selection, parameters such as temperature, operating pressure, working speeds, material, involved fluids, mating clearances, dimensional constraints, and surface roughness must always be taken into account.

During the installation of seals, great care should be taken to avoid cuts and permanent deformations that could compromise their functionality.

The choice of the most suitable material depends on the specific challenges of each application. Among the most requested elastomeric materials are polyurethane, silicone, adiprene, and other types of rubber such as NBR, HNBR, EPDM, FKM, FFKM, and SBR.
