Rudra Tubefittings, located in Kolkata, India, specializes in crafting and supplying precision-engineered collars that ensure secure tube retention and reliable sealing in hydraulic and instrumentation systems. These collars are crucial components of bite-type and compression-style fittings, providing a firm grip on tubes and preventing leaks even under high pressure and vibration. With meticulous machining and durable materials, Rudra’s collars deliver consistent performance in tough industrial settings. Their strength, precise dimensions, and resistance to corrosion make them ideal for fluid control systems, process instrumentation, and hydraulic assemblies that demand long-lasting reliability and leak-proof operation.
Typically, collars are made from carbon steel, stainless steel (SS304/SS316), or alloy steel, chosen based on pressure and environmental needs. These materials boast high tensile strength, impressive fatigue resistance, and outstanding durability under continuous loads. The collars are precision-machined to ensure they align perfectly with tubes and ferrules, creating a tight, vibration-resistant seal. Their mechanical properties include dimensional stability, wear resistance, and strong holding power under high pressure. The metallurgical integrity of these collars guarantees leak-free, long-lasting performance in challenging hydraulic and instrumentation applications.
