About Our Rubber O-Rings



Radical Polymers is a leading manufacturer of high-quality Rubber O-rings in India. The company offers rubber O-rings that can form effective seals and prevent leakage of fluids and gases. The company’s Rubber O-rings are manufactured to ensure a perfect fit in a range of applications including industrial and commercial equipment.
Radical Polymers manufactures Rubber O-rings from NBR and Viton (FKM) and high-performance materials such as Silicone and Neoprene. Each material has unique properties making it ideal for specific applications. NBR is a popular option for sealing solutions that are exposed to oil and fuels. On the other hand, Viton (FKM) is resistant to a wide range of fluids including caustic and acidic solutions. It is, therefore, suitable for a wide range of industrial applications. In contrast, Silicone is a versatile material that can resist extreme temperatures and is preferred in applications that require flexibility. Neoprene is a highly durable material that is resistant to weathering making it suitable for sealing solutions exposed to the weather. Customers should, therefore, consult the manufacturer to identify the most suitable material for their specific application.
The company offers a wide range of standard and custom-made Rubber O-rings in different sizes to suit a variety of industrial and commercial equipment. Customers can provide their preferred technical drawings or samples for the manufacture of the sealing products. Alternatively, customers can provide the inner diameter, cross-section and their intended application and the company can recommend the most suitable rubber material and hardness for their specific need.
Rubber O-rings are used in a wide range of industrial equipment as well as in automotive equipment. They are also used in pumps and hydraulic systems as well as compatible pneumatic equipment and fluid-handling systems. The primary function of a Rubber O-ring is to provide an effective seal between two surfaces while preventing any leakage of the fluid or gas being transferred. Ensuring the right fit of the O-ring is, therefore, critical to the proper functioning of a given machine or equipment.
The effectiveness of Rubber O-rings is determined by a number of factors including the size, material and the operational pressure and temperatures that the O-rings will be exposed to. Customers, therefore, need to consider several factors when purchasing O-rings including the material, hardness, groove design and installation technique. These factors will ensure that they can achieve optimal performance while prolonging the service life of the O-rings. For example, O-rings made of harder materials have better resistance to compression but poor resilience. These O-rings, therefore, require larger grooves to accommodate them during installation.
Radical Polymers specializes in manufacturing precision rubber products that meet the exact specifications of its customers. The company focuses on producing high-quality rubber products with excellent quality and tight tolerances. The company adheres to the latest international standards in the production of all its products.
