Seals
Rubber Seal Manufacturer & Supplier – Kesaria Rubber Industries
A rubber seal is a device that prevents the leakage of fluids or gases between two surfaces, creating a barrier between different parts of a machine or system so that fluids or gases stay contained while contaminants are kept out. Kesaria Rubber Industries manufactures rubber seals that offer excellent resistance to corrosion and heat while maintaining their elasticity over extended periods of use.
Kesaria’s rubber seals can be installed even on rough metal surfaces and provide a secure seal to block the entry of liquids and dust, with the lip structure of the sealing component ensuring superior sealing performance. By choosing the right combination of compound and material geometry, Kesaria’s rubber seals deliver exceptional performance – the design and specification of each seal is treated as crucial to the longevity and success of the application. From mold design and material formulation to inspection and finishing, the entire manufacturing process is coordinated once an order is placed.

Seal Types & Sizes
- Packing seals
- Lip seals
- Wiper seals
These seal types are used across a wide range of applications from automobiles and home appliances to heavy machinery and industrial equipment. The choice of seal depends on factors such as the specific application, operating conditions, temperature, pressure, and the type of fluid or gas being sealed.
Materials of Construction
Kesaria works with a wide range of materials for its rubber components, including NBR (Nitrile), EPDM, FKM (Viton®), Silicone, Natural Rubber (NR), SBR, HNBR, Neoprene (CR) and ACM.
How Rubber Seals Helps You
A rubber seal’s job is simple to describe and hard to get right: keep fluids and gases contained, keep contaminants out, and keep doing it for years under heat, pressure, and corrosive exposure. Kesaria’s rubber seals are engineered to do exactly that resisting corrosion and heat while holding their elasticity, sealing reliably even against rough metal surfaces, and backed by a manufacturing process where mold design, material, and finishing are coordinated end-to-end for each order.
Corrosion & heat resistance: rubber seals resist corrosion and heat while maintaining their elasticity over extended periods of use.
Reliable sealing on rough surfaces: seals can be effectively installed even on rough metal surfaces without compromising performance.
Blocks liquid and dust entry: provides a secure seal against the entry of liquids and dust, protecting the components behind it.
Superior sealing via lip design: the lip structure of the sealing component is engineered to ensure superior sealing performance.
