2 100 YEAR Gaskets and eals in enax rubber fabric Our gaskets in cotton-fabric ENAX do consist of fabric impregnated with elastomeric compounds through special manufacturing processes. Our pre-shaped rings with a rolled and wound structure are prepared, moulded and vulcanised in order to obtain the definitive profile. his special structure, combined with the design of profiles used for years in hydraulic systems, allows to produce gaskets with: - High elasticity; - Good mechanical resistance; - Good resistance to wear; - High resistance to pressure; - Resistance to mineral and synthetic oils; - Resistance to high temperatures. Our gaskets in ENAX, regardless of the profile, exert their function on the base of the elastic deformation they undergo during assembly in a housing having a radial section inferior to the actual width of the gasket. With this method, even in with no pressure, the sealing performance is ensured by the elastic deformation effect. When the pressure of the fluid on the gasket increases, the perfect balance among the forces acting on the gasket is created. herefore a good sealing performance is ensured even at the highest operating temperatures. Our gaskets in ENAX, if compared with other gaskets in compact rubber, offer many advantages in terms of resistance to wear and low friction coefficient. his is due to the structure of the fabric, which is able to retain particles of the retained fluid in its stitch structure. his allows to improve the lubrication and the resistance of the gasket. Our gaskets in ENAX are also able to prevent sticking phenomena of metal parts, even after long standstill periods. Vee packings or Chevron Automatic sets Our vee-packing sets, also known as automatic, do consist of different elements, such as: - Head ring section R Also named thrust ring; it has no sealing function, but it is aimed at protecting the upper V-ring from possible collision against the sharp edges of the metal housing. It is normally produced in hard material; according to the specific construction requirements, it is produced in cotton-fabric, in high hardness rubber or in plastic material. From the geometric point of view, it has a groove and some axial notches aiming at improving the sealing performance even in case of pressure peaks. he head ring is available in split form and/or glued. - Intermediate rings section V hey are the basic elements in all chevron sets; their particular V -shape has been designed for enhancing the sealing performance in high pressure. his is the reason why they are also called automatic. his profile, available in many different materials, allows a good resistance to pressure with low friction. In specific cases one or more V rings composing the Chevron set are produced in nitrile rubber; the performance of the set at low pressures is therefore highly improved. - Base ring section B Also named U -ring. his ring is assembled opposite to the pressure flow and therefore, besides supporting the V -rings, it has to be highly resistant to extrusion. As the B ring is particularly subject to wear, it is supplied with an anti-extrusion ring in special heavy-duty.
