Rubber Butterfly Seals are Important components that effectively block leakage paths in disk valves, shut-off valves, butterfly valves, and flap valves.
These seals are manufactured via Injection and Compression molding process sizes ranging from ½ inch to 42 inch Diameter.
Materials :- NBR, EPDM, FKM, Silicone, HNBR, Neoprene – WRAS, DVGW, NSF, KTW materials available
Size:- ½ inch to 42 inch Diameter.
Manufacturing Process :- Injection Moulding and Compression Moulding
Technical Specifications:- Temperature = -80 Deg C to +300 Deg C

Rubber butterfly seals are essential components designed to prevent leakage in disk, shut-off, butterfly, and flap valves. These seals ensure reliable operation, maintaining tight shut-off while withstanding a wide range of temperatures and pressures. At Harkesh Rubber LLP, we manufacture high-quality butterfly seals using both injection and compression molding processes, tailored to meet your specific requirements.

Our butterfly valve seals are engineered for precision, durability, and consistent performance. Whether it’s for industrial, water, or chemical applications, the seals are designed to fit various valve types and provide long-lasting reliability. We focus on dimensional accuracy and material performance to ensure leak-proof operation in every installation.



We use high-performance elastomers suitable for a broad range of operating conditions. Depending on the material choice, our butterfly valve rubber seals can withstand temperatures from –60°C to +200°C. Each seal is produced with stringent quality controls to maintain tight tolerances and minimize flash, ensuring a clean, precise fit.
