Over recent years, these special sealing rings, commonly defined as “stem oil seals”, have been going through considerable technological changes that deeply modified both the construction methods and the quality of the materials employed. Our standard products are represented by rubber-metal rings equipped with sealing lip and load spring: these products can be realized by using different types of mixtures such as NBR, FKM and VMQ (the most common ones) available in black, brown/green and red. In addition to this, Adriagomm plans and develops specific products such as steel and PTFE cases (mono- and bi- lip), V-RING seals, closing caps, etc: within the manufacturing cycles of these particular products, we ensure a completely free planning in accordance to our customer requirements and projects.
