Catalytic converter Inlet Cone With Flange from Lionse is a custom stainless steel welded assembly, designed as the transition connector between the exhaust manifold and catalytic converter for automotive and machinery exhaust systems.Manufactured by precision TIG welding, the component comes with pre-machined threaded ports reserved for oxygen sensor installation. The integrated flange structure enables quick and reliable bolt-on assembly during exhaust system fitting.
Lionse is a professional manufacturer with years of experience in the exhaust industry. Our catalytic converter inlet cone with flange is a bespoke stainless steel welded assembly developed for automotive and industrial exhaust systems. It serves as the critical transition component, smoothly connecting the exhaust manifold to the catalytic converter and guiding exhaust gas flow.
Adopting precision TIG welding technology, this part delivers consistent, high-quality welds. Threaded oxygen sensor ports are pre-machined on the body according to your technical drawings, allowing easy oxygen sensor installation for exhaust gas monitoring. The integrated flange design ensures a stable, leak-free bolted connection during assembly.
Optional post-processing including pickling and passivation is available to remove welding heat discoloration, restore the metallic surface, and improve the stainless steel’s corrosion resistance.
We fully support custom manufacturing. Material grade, geometry, port positions and dimensions can all be tailored to meet your unique exhaust project requirements. Every component goes through strict inspection before delivery to ensure reliable performance under high-temperature exhaust operating conditions.
