SPECIAL SEALS in ELASTOMERIC MATERIALS

In addition to traditional piston and rod seals, scrapers, back-up rings and O-rings, LIMA manufactures a wide range of special design seals made of elastomeric material, according to the customer’s needs. Thanks to the technologies at our disposal, to our staff’s long experience and know-how and thanks to our cooperation with leading companies, we can supply seals with a complex geometry holding dimensional tolerances up to a hundredth of a millimeter.

The special profile gaskets are used as an auxiliary element for many components: compressors, heat exchangers, flanges, housings, baskets, pipes, fittings, slides, panels, rollers, caps, nozzles, mechanical parts of machinery, drains, observatories and sensors. 

During assembly of the seals it is advisable to pay close attention to avoid any cuts and permanent deformations that may compromise the functioning.  The choice of the most suitable material depends from the application criticality. The most popular elastomeric materials include polyurethane, silicone, adiprene and other types of rubber (NBR, HNBR, EPDM, FKM, FFKM, SBR).

Careful check of any dimensions

The number of available profiles is remarkable: for a correct choice you must always consider parameters such as temperature, operating pressure and speed, the material, the fluids involved, the backlashes, the overall dimensions and surface roughness.
