O-ring

A GITIS O-ring is not just an O-ring

It is the result of the relentless dedication of our people, the technology, the process and the materials we use to make this product for you.

Of all sizes and qualities

We develop and produce O-rings in every dimension and quantity, from mini-rings of 0.5 mm to maxi-rings with an inner diameter of up to 2,000 mm. Other dimensions are possible in combination with special projects. Do not hesitate to challenge us with your ideas and problems!

Products & Technology

From the very beginning, GITIS has focused on developing products based on specific technologies to offer the best solution for any kind of sealing application.

Our products are known for their quality and performance: O-rings, rubber gaskets and 2K/3K co-moulded parts in high performance materials such as AEM/ACM, HNBR, FKM, FFKM, EPDM and silicone (FVMQ, VMQ), are used in sectors where high and constant performance over time is required.

Quality, performance, productivity and process innovation are the foundation of our competitiveness and growth potential in the most demanding markets. Equally fundamental is the relationship that the company creates with polymer and compound manufacturers and with customers, ensuring an exchange of information and knowledge based on transparency.

Rubber compounds are made up of polymer, fillers and chemical and plasticizing agents (processing aids, cross-linked agents, anti-aging agents, etc.).

The polymer used with a specific formulation determines the basic properties of the elastomer: temperature range and chemical resistance.

Fillers improve the mechanical properties of elastomers such as hardness, resistance to abrasion and elongation, setting and aging behaviour. Through an irreversible cross-linking with large meshes, also known as vulcanization, the compounds become elastomers that behave in an entropic-elastic way in the range of the temperature of use.

Our product portfolio meets all customer demands and requirements both in terms of temperature range and physical and chemical properties, also in the most recent new applications in our strategic market segments.
